I love all dogs -- the big ones and the small ones, the portly ones and the stringy ones, the happy ones and the sad ones! I am happy to walk or run with them. Growing up, I had labs and boxers, so they are my favorites. They were all boys and pretty big dogs so I am used to some pulling on the leash. Also, and not at all in a bragging way, I wrestled in college, so even if your dog tends to pull pretty hard on the leash, I should be able to handle it! I have a broad range of availability, including weekends and weird times of day and night. My granddad was a vet, so I grew up watching a guy who was extra nice to animals and I try to be the same way.
