In elementary and high school I pet sat regularly for 6-8 neighbors, and shared responsibility for 2 family dogs. Some preferred house sitting as well as pet sitting, others like occasionally visits. I am now a happy owner of 2 fur kids. I love all breeds and have experience walking and caring for large and small dogs. I can walk a few dogs at a time (I have walked my 2 large dogs as well as my parents 3 medium dogs at one time.) I regularly use positive reinforcement training with all dogs.
