i have had years of experience dog sitting many neighbors dogs and have walked my own dog at home every day for years, i dont know what we deserved to have such beautiful, awesome animals. I can walk as far as your dog needs to go and might have more fun playing fetch than he does if that is what your dog prefers. I am good with old and young dogs as i have had two dogs ranging in age, and have put much time into training them. To me its not a job its a hobby and i miss my dog at school so there is no doubt your dog will be getting tons of love and attention. your dog will stay in tip top shape mentally and physically with me :)
