If you're allergic to dogs, you might only be allergic to males, according to a new study

According to the Asthma and Allergy Foundation of America says three in 10 people with other allergies will also have pet allergies. Up to 20% of the population have pet allergies, which means that having a four-legged friend isn't always feasible. There are many health benefits to dog ownership, like such as higher survival rates in the instance of a heart attack, and as it turns out, you might not have to forgo the companionship and benefits of having a dog just because you're allergic. You might not be allergic to all dogs.


Dog breeds that don't shed or are hairless are believed to be "hypoallergenic," but that's not necessarily the case. Pet allergies aren't triggered by animal hair. Proteins in the, saliva, and dander of cats and dogs are what actually cause allergic reactions. "Up to 30% of people who are allergic to dogs are actually allergic to one specific protein that's made in the prostate of a dog," Dr. Lakiea Wright, an allergist at Brigham and Women's Hospital in Boston, explained to CNN.

So far, six specific dog allergens have been identified, and yes, it's totally possible to be allergic to one dog protein and not the others. In other words, someone who has dog allergies might not have reactions to certain dog breeds – and even genders. So, it's totally possible to still get a dog. "If you're allergic to only that specific protein in the male dog, you may be able to tolerate a female or a neutered dog," Wright told CNN.

Male dogs produce a specific protein called Can f 5. The protein, which is made in the prostate, spreads to dog's hair and skin when they urinate. "These proteins are very lightweight, so they get dispersed in the air as the animal moves around," Wright told CNN. "They can also stay in the air for a long time and land on our furniture, mattress, even our clothes."

Allergists can test for allergies to Can f 5 through a blood test or skin prick. "When we suspect a dog allergy, we're testing for that whole allergen," Wright told CNN. "But then we're also looking at specific proteins, the parts that make up the whole, to refine that diagnoses."

Interestingly, dog ownership might actually prevent the development of future allergies. Studies have found that exposure to a dog before the age of one might protect against future allergies, and that being around dogs can lower children's risk of asthma.

Fortunately, not all dogs are boys and not all cats are girls, so it's totally possible to get a girl dog that doesn't make you cough and sneeze.

When "bobcat" trended on Twitter this week, no one anticipated the unreal series of events they were about to witness. The bizarre bobcat encounter was captured on a security cam video and...well...you just have to see it. (Read the following description if you want to be prepared, or skip down to the video if you want to be surprised. I promise, it's a wild ride either way.)

In a North Carolina neighborhood that looks like a present-day Pleasantville, a man carries a cup of coffee and a plate of brownies out to his car. "Good mornin!" he calls cheerfully to a neighbor jogging by. As he sets his coffee cup on the hood of the car, he says, "I need to wash my car." Well, shucks. His wife enters the camera frame on the other side of the car.

So far, it's just about the most classic modern Americana scene imaginable. And then...

A horrifying "rrrrawwwww!" Blood-curdling screaming. Running. Panic. The man abandons the brownies, races to his wife's side of the car, then emerges with an animal in his hands. He holds the creature up like Rafiki holding up Simba, then yells in its face, "Oh my god! It's a bobcat! Oh my god!"

Then he hucks the bobcat across the yard with all his might.

Since March of 2020, over 29 million Americans have been diagnosed with COVID-19, according to the CDC. Over 540,000 have died in the United States as this unprecedented pandemic has swept the globe. And yet, by the end of 2020, it looked like science was winning: vaccines had been developed.

In celebration of the power of science we spoke to three people: an individual, a medical provider, and a vaccine scientist about how vaccines have impacted them throughout their lives. Here are their answers:

When John Scully was born, America was in the midst of an epidemic: tens of thousands of children in the United States were falling ill with paralytic poliomyelitis — otherwise known as polio, a disease that attacks the central nervous system and often leaves its victims partially or fully paralyzed.

"As kids, we were all afraid of getting polio," he says, "because if you got polio, you could end up in the dreaded iron lung and we were all terrified of those." Iron lungs were respirators that enclosed most of a person's body; people with severe cases often would end up in these respirators as they fought for their lives.

John remembers going to see matinee showings of cowboy movies on Saturdays and, before the movie, shorts would run. "Usually they showed the news," he says, "but I just remember seeing this one clip warning us about polio and it just showed all these kids in iron lungs." If kids survived the iron lung, they'd often come back to school on crutches, in leg braces, or in wheelchairs.

"We all tried to be really careful in the summer — or, as we called it back then, 'polio season,''" John says. This was because every year around Memorial Day, major outbreaks would begin to emerge and they'd spike sometime around August. People weren't really sure how the disease spread at the time, but many believed it traveled through the water. There was no cure — and every child was susceptible to getting sick with it.

"We couldn't swim in hot weather," he remembers, "and the municipal outdoor pool would close down in August."

Then, in 1954 clinical trials began for Dr. Jonas Salk's vaccine against polio and within a year, his vaccine was announced safe. "I got that vaccine at school," John says. Within two years, U.S. polio cases had dropped 85-95 percent — even before a second vaccine was developed by Dr. Albert Sabin in the 1960s. "I remember how much better things got after the vaccines came out. They changed everything," John says.
