I walk groups of dogs everyday off leash in a beautiful, 20 acre dog park near my home here in East Hampton. I know most of the dogs that I encounter, there as most of the people who walk their dogs there are local. Occasionally we will meet a dog that we are unfamiliar with. One of my dogs is an extremely friendly ( but rowdy Frenchie) she has never met a dog or human that does she doesn't like in her relatively short life. However , sometimes she meets a dog that does not like her?
