I have had dogs my whole life. I always watched and walked the neighbors dogs when needed. I have experience with small, medium, and large dogs. Have watched and walked five dogs at one time. Had multiple experiences watching and walking several different breeds at the same time. Willing to watch breeds that are known as being aggressive (Pit-bulls, Rottweiler's, and Chows). And I am not afraid to give a belly tickle if needed ;)
