UPS drivers get real about whether their jobs are really worth the big paychecks

Jobs as UPS drivers have become extremely sought after.

Being a UPS driver comes with excellent pay and benefits and a whole lot of hard work.

For the past few generations, the standard wisdom was that if you wanted a career that paid well you should to go to college and get a degree. However, there are and have always been well-paying careers in non-academic fields, from the trades to starting a business to driving a delivery truck for UPS.

When a UPS driver shared his weekly paycheck on social media in 2023, people were surprised to learn how lucrative a gig it can be—$44/hour kind of lucrative, in his case. Drivers were already known for being paid well, but a union win in the summer of 2023 bumped up pay even more. Working 40 hours a week at $44/hr would earn you over $90K a year, and according to folks who work for the company, it's not unusual for UPS drivers to top out in comfortable, six-figure salaries.

But even with that pay, is being a UPS driver worth it? Here's what experienced drivers have to say.

A UPS employee who'd been working as a package handler for a couple of years was considering applying for a driver position and posted a list of questions for UPS drivers on Reddit. The following answers are pulled from that Reddit post and others:

How much can a UPS driver expect to make?

"Depends on where you are but generally $40 [per hour] after 4 years." – Shasfowd

"We have a guy that never graduated high school. He made $120k last year." – MrOddYazz

"Believe it, I took over thirty unpaid days off last year and still breezed past a 100." – _aIIan_

"127k last year. On track for 130k this year. 👀" – chavo2021

What are UPS driver hours like?

"You’ll make a good amount of money, but you won’t have a ton of time to yourself and with your family." – WassabiReindeer

"About 50-60 hours a week." – Shasfowd

"This job has one of the worst work/life balances and I worked In a hospital before this and have had many jobs. This one will have you making stacks of money with great benefits but who knows how far that goes. If I didn't have a huge medical problem I would've left years ago but like many others I am trapped. If this was a regular 40 hr a week job I'd tell everyone I have one of the best jobs In the world. However, that is not the case." – AnimatedAnixa

"Expect to work a butt load of overtime." – Joe12van

"Between 50-60 hours a week. Basically for the first couple years, don't make plans in the evening time." – KCD_OG-78

How difficult is it to become a UPS driver?

"Pretty difficult. Classes will be around 10-20 drivers, and by the time training is finished there will be about 5 of you. By the time you're done with probation there will be 3 of you and within a few years at most you'll be the only person from your training." – Shasfowd

"The first two years will be the toughest. I'd say if you can make it through that, it gets easier.....well mentally, not necessarily physically." – KCD_OG-78

"Qualifying to be a driver is one of the most stressful things I have ever done based on my life at the time I went to qualify." – Financial_Skirt4251

"It’s all by seniority, so you have to do your time loading trucks and wait. Loading isn’t easy and is only a part time job. Usually loading 3-4 trucks yourself on a morning shift or loading a whole tractor trailer front to back floor to ceiling by yourself at night. There are other part time shifts. You can wait years to get enough seniority to bid a chance at driving, but it depends on the location you work.

If you made it this far, you’ll get taken out on a road test by a supervisor. If you can drive ok, they’ll send you to get a D.O.T. health physical by one of their approved doctors.

After that, you get sent to ups boot camp and have to pass tests on all the basics and knowledge to drive. Don’t be late, have your uniform ironed and clean, and memorize the 5’s and 10’s.

Then the hard part begins. It’s a 30 working day torture test to see if you can hit the company’s extremely unreasonable production numbers while driving, learning a route, working safely, figuring out how to manage customer relations in a way where you can keep moving, all while under extreme time management.

If you make it, you’ll then be bounced around on dozens of routes covering them and learning all of these things over on each one until you have been a driver long enough to bid a permanent route assignment.

You better believe every driver you see out there has earned their place as a driver." – Hitsthebrakesnows_

What else should people know about being a UPS driver?

"I worked as a computer programmer freelance 2 years before UPS. And I would pick UPS again and again. Even though we get treated like sh*t and most days are a nightmare. Trust me. Without the $100k+, and benefits. I would not be here." – AdProfessional9809

"I like it, but it's not for everyone. I know a lot of preloaders that have given it a shot only to decide they don't like it." – Shasfowd

"If you top out and kill the over time you can probably make 80-120k a year. But this is a hourly position and you work for your money. Whenever a driver brags to me how much they made last year. I cringe and sauté because I know how many hard hours they work. Not a easy job not a easy start. But once you get seniority and master the craft. Seems to be rewarding." – sprucetre3

"Have an exit plan if you decide to become a driver. Being good at manual labor and driving a truck can only carry you so far. Especially because the company will demand most of your time.. your life around work can easily deteriorate. Be prepared to be tired a lot…if my son were 19 and he wanted to be a UPS driver..knowing what I know and having dealt with what I’ve dealt with I would try and steer him into a different career BUT to each their own." – BEAR_STORM

" I wouldn't recommend this as the first career choice for my child. I always said it's a horrible plan A but great plan B." – gunstarheroesblue

"Been driving for a year and a half now. Benefits are phenomenal. I've always done labor, decided it won't be for me. I start college in January. Thinking of going part timer here and UPS helps to pay for college." – DCostalot

The general consensus seems to be that the early years are tough but it gets better if you stick it out, the job is demanding with long hours and you will work long hours at Christmastime, but the pay and benefits are phenomenal. Some people love it, some don't. Like all jobs, being a UPS driver has its positives and negatives, and whether it's worth it is an individual judgment call.

Gen Z is the first generation less cognitively capable than their parents but Denmark has a solution

"Since the late 1800s, every generation has outperformed their parents."

Gen Z is the first generation less cognitively capable than their parents. Denmark has the solution.

Nearly every parent hopes their child will be better off than they are: smarter, more secure, and more well-adjusted. Many parents see this as a stamp of successful parenting, but something has changed for children growing up today. While younger generations are known for their empathy, their cognitive capabilities seem to be lagging behind those of previous generations for the first time in history.

Dr. Jared Cooney Horvath, a teacher turned cognitive neuroscientist who focuses on human learning, appeared before Congress to discuss concerns about cognitive development in children. In his address to the members of Congress, he says, "A sad fact that our generation has to face is this: our kids are less cognitively capable than we were at their age. Since we've been standardizing and measuring cognitive development since the late 1800s, every generation has outperformed their parents, and that's exactly what we want. We want sharper kids."

Horvath explains that the reason this happens is that each generation has gone to school longer than the previous generation. Gen Z is no exception to the longer duration of time spent in school, but they're the first ones who aren't meeting this normal increase in cognitive development. According to the cognitive neuroscientist, the decline is due to the introduction of screens in the classroom, which started around 2010.

"Across 80 countries, as Jean was just saying, if you look at the data, once countries adopt digital technology widely in schools, performance goes down significantly. To the point where kids who use computers about five hours per day in school for learning purposes will score over two-thirds of a standard deviation less than kids who rarely or never touch tech at school," Horvath reveals.

In most cases, the decline in performance doesn't result in better strategies. The neuroscientist shares that the standardized testing has been adjusted to accommodate lower expectations and shorter attention spans. This is an approach that educators, scientists, and researchers went to Capitol Hill to express wasn't working. But not every country is taking the approach of lowering standards to meet lowered cognitive ability. Denmark went in the opposite direction when it realized their students were slipping behind.

France24 recently interviewed educators in Denmark following their seemingly novel approach to students struggling with cognitive development. Since the beginning of the 2025/2026 school year, Denmark has not only been having students turn in their cellphones, but they've also taken tablets, laptops, and computers out of the classroom. No more digital learning for the majority of the school day. Danes went old school by bringing back physical textbooks, workbooks, and writing assignments. The results have been undeniable. Even the students can't seem to deny the success of the countrywide shift in educational approach.

"I think the biggest issue has been that, because we kind of got rid of the books and started using screens instead, that we've noticed that a lot of the kids have trouble concentrating, so it's pretty easy to swipe with three fingers over to a different screen and have a video game going, for example, in class," Copenhagen English teacher, Islam Dijab tells France24.

Now, instead of computers being part of every lesson, Denmark uses computers very sparingly and with strict supervision. One student says that it has been nice not having screen time at school because she loves to read and write. But it wasn't just the lack of attention span children were developing, they were also developing low self-esteem and poor mental health due to the amount of time spent on devices.

The data showing the negative impact of screens on teens' brains has prompted a nationwide change in Denmark that extends outside of the classroom. Afterschool activities are eliminating or extremely limiting electronic use. There is also a national No Phone Day that encourages everyone to put away their devices for the day, and Imran Rashid, a physician and digital health expert, is petitioning parliament to ban social media use for children under the age of 15. The no phone movement in Denmark is a nationwide effort that hopes to right the ship before another generation feels the effects.

Inside a Dutch 'dementia village,' where the whole neighborhood is designed for memory loss

The Hogeweyk provides a sense of "normalcy" for people living with dementia.

dementia, dementia village, elder care, memory care, alzheimer's disease

In a dementia village, people get to choose where they go.

No matter how much caregivers may want to keep a loved one with dementia in their home, it's not always feasible. Living with dementia is not easy, nor is living with someone who has dementia. But moving a loved one with dementia into a traditional care facility isn't always ideal, either. It can be difficult to find a suitable living situation that ticks all the boxes for what a family and their loved one would want.

That's where a "dementia village" comes in as an alternative. Instead of trying to fit a person with dementia into a living situation that either isn't designed for them or is overly focused on their limitations, a dementia village is an environment designed specifically to help people with severe dementia feel safe and free and live as normal a life as possible.

- YouTube www.youtube.com

The Hogeweyk was the world's first dementia village, founded in 2009. Since then, the idea has been replicated in dozens of locations all over the world. The concept is quite simple: A full, self-contained neighborhood where people with dementia can walk around freely without fear of getting lost, where everyone from shopkeepers to restaurant servers to salon workers are trained in dementia care, and where people who are losing their memory to dementia diseases are treated as people who still have aspirations.

Eloy van Hal, one of the founders of the Hogeweyk, explained to Vox how the guiding principle of the village is "normalcy." Traditional nursing homes keep all residents under one roof, and they are subject to do whatever program the institution provides for them. In the Hogeweyk, people live in small groups of six or seven in apartments with furnishings like they'd have at home. Distinct landmarks in the public space help residents know where they are, and putting a theater, grocery store, barber shop, etc. in separate buildings encourage movement through the neighborhood.

"It's about choice, choice, choice, where you want to be during the whole day and with whom," said van Hal. The idea is to balance safe design with controlled risk, allowing for as much of a normal life as possible.

The one downside to the village concept, of course, is cost. Without adequate funding assistance from governments, living in a dementia village can be prohibitively expensive.

Does it really make a difference for residents, though? Has it been proven that outcomes are better than traditional care models? With dozens of villages now being used around the world, research is ongoing, but the data from the Hogeweyk is promising. People in the comments of Vox's by Design video shared how such facilities have been life-changing for their loved ones and how traditional care doesn't always meet the needs of people with dementia.

"My grandmother had dementia and when her caretaker who was my grandfather (her husband) passed unexpectedly we had to scramble to get her into a memory care facility in the US. The first place she was in temporarily was so sad, I could see her spirit drain but after about a year we were able to get her into a "village" and the quality of life difference is nothing short of ASTOUNDING! She could function in a way that was familiar and comfortable to her and not be in a foreign hospital setting. The abrupt change from a home where they are familiar, to a clinical setting must be very disorienting and upsetting to these people. That side of my family had mental health issues and memory loss starts early, so I know it will happen to me to some extent and I only hope I can have people take care of me as well as in this Hogeweyk."

"I've worked in a nursing home through high school and college. While I can't say it was the worst place for dementia patients, it certainly did not work well for all of them. One patient once tried to wedge herself through the door begging to go outside with me and I even had patients confide in me that they hated being institutionalized, they missed being able to live a normal life, being part of a real community, and being able to come and go as they pleased. This concept is probably the closest thing possible to a normal life a dementia patient could ever have."

"A relative of mine used to get aggressive, violent and angry when she would encounter a locked door in the institution she was in. She couldn't understand why there would be a locked room in what she understood to be 'her home', this would take a lot of calming down and management, only for her to discover another locked door, and kick off again. I love these village based models as they allow autonomy for residents, and have an individual experience. Just because someone has a brain disease doesn't mean they aren't entitled to the very best care. I hope the govt spends far more on these establishments in the future."

"As he said at the end, people with dementia are still people—even if there is proven to be no benefits to this model over a care home, I would much prefer to have dignity in my final days than live in a clinical trap. Love all the incredible ideas the Netherlands come up with."

Dementia care is something Americans are going to have to look at closely. According to The Alzheimer's Association, the number of people living with Alzheimer's is set to nearly double from seven million to 13 million by the year 2050. As more of our elders require full-time care, the more we'll have to consider prioritizing putting resources into things like dementia villages.

Everyone deserves safety and a good quality of life. The Hogeweyk is a great example of what it looks like to view people with dementia as people first and to care for them accordingly.

Want your home to be 'the house' for your teens? Mom shares her 4 tips to make it happen.

Don't mistake being "the house" with being the "cool house."

Amy White explains how her house became "the house" for her teens.

I grew up in "the house." In high school, my home was the designated place where my friends gathered, sometimes in big groups, sometimes just my small core squad. My three best friends spent the night there almost every Friday and/or Saturday night for four years straight. We devoured Totino's frozen pizzas by the dozen, inhaled soda, and laid waste to any snacks or leftovers that were brave enough to survive in the kitchen. Not only that, but my house was pretty small — four teenage boys took up a lot of space in the living room (the whole thing) and made a lot of noise playing video games deep into the night. It must have driven my parents and older brothers crazy. It's a wonder anyone put up with it.

Or so I thought when I was younger. When I became a parent myself, I started to understand a little more why my mom and dad were so willing to host and feed all my friends and me every single weekend. Why the outrageous grocery bill and constant chaos in the house were probably a small price to pay.

Mom explains how to make your house 'the house' where teenagers hang

One mom has perfectly encapsulated the value of turning your home into "the house" for your kids and their friends, and exactly how she did it for her family.

teens, teen house, teens hanging out, teens having fun, teenagers Teens hanging out in a living room.via Canva/Photos

Amy White shared a reel on Instagram showing her college-aged son hanging in her dining room with a group of friends playing cards. The text overlay reads "What makes your kids' high school friends want to come over, play cards & spend the night on their College Christmas Break." I think most parents can agree that we want our kids to keep coming home as long as possible! So how exactly did White pull this off?

Her explanation in the caption was spot-on.

First, White says that you have to start early. Become "the hang out house" in high school or even earlier. Then you have a better chance of holding onto the mantle into your kid's college years.


Next, be ready to stock the house with snacks and drinks, and don't make a fuss when your kid's friends have at it. "The kids knew we had food," she writes, "BUT they also knew I didn't care what they had. They knew they could eat anything in my pantry and fridge."

Third, and this is a big one, don't mistake being the "cool house" for being "the house." Some parents choose to allow their underage kids and friends to drink alcohol under their supervision, but you don't have to bend your morals and the law to lure the squad over to your place. Pizza and Coke is plenty to keep most teens happy. "We were not the house that served alcohol or even allowed the kids to bring alcohol to our house. And Guess What?? The kids still came and wanted to hang at our house!"

Fourth, always say Yes (as often as possible, anyway) when your kids want to have friends over. "They know my answer is 99% of the time YES," White writes. "You have to have your kids take the leadership of offering your home and if your home was 'open' to their friends in high school, they know it will be 'open' to their friends in college."

As a bonus tip, White pleas with parents not to worry about the mess having friends over makes. "I love a clean house and organization, BUT I would much rather have a crazy messy house for the kids where memories are made than a quiet house with nothing going on just to keep my house 'clean.'"

Should parents allow teens to drink at home?

There's an age-old debate over whether parents should allow teens to drink at home because it's better than if they do is unsupervised or keep their home dry as a bone. A recent study out of the University of Buffalo found that kids who grew up drinking at home had a greater chance of having addiction problems when they got older. "A robust relationship was found between parental permission to use alcohol during adolescence and increased alcohol use frequency and quantity, alcohol use disorder symptoms, and alcohol-related harms in young adulthood," the study says.

White writes, "It's worth being 'the house', so let go of control & get to know your kids friends." Commenters agreed.

White's video went viral to the tune of 8.5 million views and hundreds of comments. Parents shared their own experiences of what it's like being the default hang out house.

"Our house was the high school hangout for my son and friends... every weekend... I loved it!! Miss it now that they are all college graduates and have moved away. I love seeing them when they do come home for the holidays"

"A wise man once said don't be the house with the alcohol. Be the house with the food."

"Amy 1000% agree!!! My house is full of teenagers on the weekends and I love every bit of it. Even though I wake up to a kitchen that looked much different from when I left it"


teens, teen house, teens hanging out, teens having fun, teenagers Teenagers eating pizza.via Canva/Photos

"We never allowed alcohol, drugs, bad language, always respectful, and guess what, our house was always the house where the kids hung out. First my daughter, then my son. Through grade school, high school, then when my kids went out of state for college their college friends would come spend a couple weeks during the summer. I always thought of it this way, I loved knowing my kids friends and, who knows, maybe some of those kids, especially during the younger years, just maybe those kids just needed an adult to care. Anyway, it was always fun to have them here!"

"It used to crack me up when my daughter would bring over a bunch of her friends (girls and boys) in high school and instead of hanging out in the family room they all wanted to crowd into either the kitchen with me or our tiny office and happily share all the gossip with me."

Experts say that knowing your kids' friends, and their parents, can have huge benefits. Not only will it bring you the peace of mind of knowing where your kid is and who they're with when they get to those crucial high school years, it has been shown to tangibly improve kids ability to create positive relationships and problem-solve collaboratively. Plus, it can actually be really fun! Kids and teens are the funniest, silliest, most interesting people on the planet. Having a house full of them is messy and loud, but it's always a good time.

One caveat: "don’t feel bad if your house isn’t the chosen house," one commenter reminds us. "Just be happy your kid has a good group of friends and be thankful they have somewhere safe to hang out."

Guy uses a Ziploc bag to show why some things look backwards in mirrors while others don't

We get it now!

Why is text reversed in mirrors?

Have you ever wondered why text shows up backwards in a mirror? It's confusing to our brains because it doesn't seem like anything else is flipped like that. If we turn our head, it doesn't move the opposite direction in the mirror. Or does it? After all, right-handed you is actually left-handed you in the mirror. Right? (Wait, is that right?)

Mirrors can be confusing despite not being very complicated. A mirror image is simply a reflection of what's in front of it. But when someone else is looking at us head on, they don't see text in reverse, so why don't we see what other people see when we see ourselves in a mirror?

mirrors, mirror, how mirrors work, mirror image, text in mirrors Woman smiling in a mirror.Canva Photos.

(If you think this is a super stupid question with a super obvious answer, congratulations. Pat yourself on the back and scootch along so the folks who don't fully grasp the physics of mirrors can enjoy a demonstration that makes it a little easier to understand.)

"Why do mirrors reverse text?" asks the creator behind @humanteneleven on YouTube. "You might think it's just a property of mirrors—they flip things from left to right—but that's not true." He then picks up a metal arrow to show that it points the same direction in the mirror as it does in real life. So why is the text flipped when the arrow isn't?

- YouTube youtu.be

He then holds up a book to show how the text on the book cover appears backwards, just like the shirt. But when he holds up a Ziploc bag with the word "HELLO" written on it, the word shows up properly.

Why? How?

It's because he had to flip the book over to see the cover text in the mirror. The baggy, on the other hand, he could just hold up and see the letters through the transparent plastic, just as we see them in real life. If he flips the baggy over like he did the book, the text shows up backwards in the mirror, just like it does in real life.

"So it's actually not the mirror that's flipping anything from left to right," he says. "It's the human."

People appreciated the simple, straightforward explanation and demonstrations.

"One of the most insightful demonstrations I've seen. It's simple and explains the phenomenon. Well done!"

"While I've heard this explanation many times before, I've only recently seen it demonstrated with text-on-transparency, which is what really makes it click. Great video!"

"Love these sorts of demonstrations. It’s a bit of a complicated one, but I love seeing how different people's minds work when explaining simple things like this. My kid explains it with “left is on the left, right is on the right, things aren’t flipped, they are mirrored” but it’s true that you are the one who flips things and I’ve never thought of it that way before."

"Oh my God, I haven't understood explanations from physics videos about why mirrors flip but this, gosh this helps."

Mirrors have been hilariously befuddling people in other videos as they try to figure out how the mirror "knows" what's behind a barrier placed in front of objects.

@sarahcoome

this is kinda creepy 👀 #mirror #relatable #creepy

Is this something all of us should probably have learned in high school? Yes. Do all of us remember everything we learned in high school? No. Does the scientific explanation make perfect sense to everyone even if it's explained in detail? Um, no.

Like the reversed text question, having a simplified explanation that doesn't fully get into the nitty gritty physics and geometry of how mirrors work is helpful for some folks.

- YouTube youtu.be

For those who want a bit more scientific substance to their explanations, this next video does a good job of giving a bit more detail while still keeping the explanation simple. It even uses a visual diagram to explain:

- YouTube youtu.be

And for those who say, "This is so basic! How do people not understand this?" here's a video that really does get into the nitty gritty physics and geometry of how mirrors work, diving into ray and wave optics, photons, wave functions, probability, and quantum mechanics. It's only 12 minutes, and it manages to entertain while explaining, but it certainly blows the notion that understanding mirrors is super simple.

- YouTube youtu.be

As one commenter wrote, "I thought I understood mirrors. I understand mirrors even less now. And that's a compliment."

Isn't science fun?

8th grader's award-winning experiment finally reveals if a dog's mouth is cleaner than a human's

You've heard the myth. Now read the science.

Dogs come in a wide variety of breeds, along with their own unique personalities and needs. They can be guardians, helpful workers, loyal friends, snuggly companions, but there's one thing almost all dogs have in common: Licking.

Sure, some dogs lick way more than others, but it's rare to find a dog who never licks anyone or anything. Many dogs communicate and show affection by licking, which is sweet—if a little gross—depending on how slobbery they are. There's a common saying that dogs' mouths are cleaner than humans', which is a bit hard to believe when you see what some dogs put in their mouths, but it is true?

What does science say about dog tongues and saliva? Is a dog licking our face something we should worry about?

It turns out, the answer to whether a dog's mouth is cleaner than ours isn't super straightforward.

An 8th grader named Abby tackled this question in a science experiment that won her a Young Naturalists Award from the American Museum of Natural History in 2011. Her family had gotten a dog and her mom kept telling her not to let the dog lick her face because dog mouths are full of bacteria. Instead of arguing, Abby decided to find out herself if this was true.

"I hypothesized that human tongues would be cleaner than dog tongues," she wrote. "I thought this because humans brush their teeth at least once a day. I hypothesized that dogs' tongues would be dirty because they were always licking dirty things like garbage."

After diving into the research about bacteria that live in and on humans and dogs, Abby decided she had a testable hypothesis. But this wasn't any old middle school science experiment. She applied for and got a grant to the State Hygienic Lab at the University of Iowa, where she was assigned a mentor to work with her.

You can read the nitty-gritty details of her experiment here, but it involved a lab, swabs, agar plates, and more. Here was the conclusion:

dog experiments, dog tongue cleaner than humans, experiments by kids, cool science, dogs, fun science, experiments, science A dog's tongue close-up. Photo credit: Canva

"I concluded that dog and human mouth flora are very different. (Flora means the bacteria found in a mouth or anywhere else.) The bacteria found in human mouths are more similar to another human's oral bacteria than the bacteria found in a dog's mouth.

"I also concluded that dogs' mouths are cleaner than humans' in some ways, and dirtier in other ways. Humans have more bacteria in their mouths than dogs do, based on the total number of bacteria. Most of the humans had a 'moderate' number of bacteria, and most of the dogs had 'few' bacteria. A possible explanation of this might be that dogs pant a lot, and maybe while panting, bacteria falls off their tongues along with their saliva. But dogs had more types of bacteria. The average number of different bacterial colonies in a dog's mouth was about 5.7. The average number of different bacterial colonies in a human's mouth was about 4.1. I think this is so because dogs sniff and lick a variety of things, like carpets, floors, chairs, grass, etc., so they pick up bacteria from many places."

But what about the licking of our faces? That's a bit of a subjective call, but Abby's results gave her some peace of mind:

"In conclusion, will I let my dog continue to lick me? The answer to the question is yes!" she wrote. "I will feel guiltless about letting my dog lick me because I found out that human and dog oral bacteria are different, so my dog's oral bacteria present no harm to me."

What do the experts say?

According to Colin Harvey, professor at the University of Pennsylvania’s School of Veterinary Medicine and executive secretary at the American Veterinary Dental College, comparing dogs' mouths to humans' mouth is "like comparing apples to oranges." As Abby found, the microbes in a dog's mouth are very different than those in a human's.

The American Kennel Club elaborates:

"Most of the bacteria in your dog’s mouth aren’t zoonotic, which means you probably won’t get a disease from a big old doggy kiss. There are exceptions to this. Dogs that eat a raw diet are at an increased risk of contracting salmonella, which can be spread to humans. You also probably shouldn’t share kisses with a dog that regularly raids the litter box.

In other words, kissing your dog is less risky than kissing another human, but that doesn’t mean that your dog’s mouth is necessarily cleaner than a human’s—they just have a mostly incompatible set of germs."

Keeping your dog's mouth healthy through regular teeth cleaning and dental check-ups can also help prevent issues that could potentially come from dog licks.

So there you have it. If your dog doesn't eat a raw diet and doesn't go snacking in the cat box (or some other equally fecal-bacteria-ridden place), their kisses are probably not going to hurt you. Guilt-free pooch smooches for the win!
