Best Dog Category: Carmen Cromer "Jurassic Bark," Pittsboro, North Carolina

"My golden retriever, Clementine, loves to stick her face in front of the hose while I water the plants. Her expression in this photo made me think of a tyrannosaurus rex, hence the title, "Jurassic Bark." Duh nuh nuuuh nuhnuh, duh nuh nuuuh nuh nuh, dun duh duuuh nuh nuh nuh nUUUUUUhhhh." – Carmen Cromer

Best Cat Category: Kathrynn Trott "Photobomb," Ystradgynlais, U.K.

Best Horse Category: Mary Ellis, "I Said 'Good Morning,'" Platte River State Park, Nebraska

"I like to visit the stable horses before I begin my hike at the State Park. This is the reply I received when I said 'Good morning.'" – Mary Ellis

All Other Creatures Category: Sophie Bonnefoi, "The Eureka Moment," Oxford, U.K.

"Cutie and Speedy are two chicks hatched from eggs placed in an incubator at home in August 2020. They spent their first few weeks indoors. In the photo, they are just over two weeks old. They were curious about everything. This is the day they discovered their own shadow. It was hilarious to see them wondering and exploring that 'dark thing' that was moving with them!" – Sophie Bonnefoi

Junior Category: Suzi Lonergan, "Sit!" Pacific Palisades, California

"Our granddaughter gave the command to sit. Beau is very obedient." – Suzi Lonergan

Pets Who Look Like Their Owners Category: Jakub Gojda, "That Was a Good One!" Czech Republic

"This photo was taken by accident during the photography of my ex-girlfriend with her beloved mare. For this cheerful moment, I thank the fly that sat on the horse's nose and he instinctively shook his head." – Jakub Gojda.

Highly Commended: Chloe Beck, "Hugo the Photobomber," Walsall, U.K.

"This is my best friend Faith, her husband Alex, and their cheeky Sproodle, Hugo. Faith wanted a photograph to mark a special occasion—her first outing after shielding at home for 14 months. Hugo jumped into the frame at just the right moment!" – Chloe Beck

Highly Commended: Luke O'Brien, "Mumford and Chum," Coventry, U.K.

"Losing the opportunity to play with my human bandmates during lockdown, Flint, my rescue dog, soon taught me that we didn't just have sharp bones in common, but musical ones, too. He soon became the perfect substitute for a collaborative stomp up at home, so much so that we felt we deserved our own band name (Muttford and Chum). With my camera set up remotely during this shoot, I think it's fair to say that the image is proof that his conviction as a performer matches my own." – Luke O'Brien.

Highly Commended: Kathryn Clark, "Wine Time," Cichester, U.K.

"It's that time of day again! Little Blue enjoys it almost as much as me." – Kathryn Clark.

Highly Commended: Diana Jill Mehner, "Crazy in Love With Fall," Paderborn, Germany

"This is Leia. As you can see, she definitely loves playing with all the leaves in autumn. It was really tricky to take this picture because you never know what the dog is going to do next." – Diana Jill Mehner.

Highly Commended: Colin Doyle, "Nosey Neighbor," Bromsgrove, U.K.
