Mark Taylor may not have any training as a photographer, but that doesn’t stop him from taking amazing animal photos. From his studio in Southeast England, Taylor has made a big business out of photographing man’s best friends, following in the footsteps of his late mother, Jane Burton. Most of the animals he works with are babies, who are more comfortable in front of the camera than older animals.

Photo: Taylor often uses animals that belonged to friends of his late mother, including this Italian Spinone puppy chewing his tail. Baby animals make ideal subjects, as the older dogs and cats get, the warier they are of spending time in a studio. And his trick for getting this small subject to pose? Dog treats, of course.
