I worked for one year at an animal clinic that included boarding, we frequently let the animals out about every two hours along with making sure the dogs were being well taken care of no matter how aggressive. My mom works as a vet tech and has almost her whole life, I've owned 3 dogs, 6 cats, and two pigs (weird I know) you’ll only get the best care available for your dog(s) no matter the dog size I’m capable of handling it, I especially love larger fluffier dogs! What sets me apart from other sitters is my work ethics, I’m always early, my attention is focused on the task at hand. Why not choose someone who loves animals? Otherwise you might have a mess or two to clean up
