My family's had labs since I was born, and growing up in a neighborhood full of dogs means lots of teen dog walking/sitting jobs. Our labs have required some senior care, as have previous clients, and I am experienced with leash training as well. I adopted a kitten in college so I have some experience with babies and LOTS of cleaning skills. I work part-time in the evenings Thurs-Sunday, I don't have much of a routine and can fit in a walk any time Monday through Wednesday (if not sitting). I think it's important to pay attention to a pet's body language and behavior in caring for them, so this question would really vary for each animal. I am unable to board, but I have sat and/or walked dogs with a variety of needs.
