I agree with what several of you are saying about dog parks-- if mine were more interested in playing I might take them to a local one which usually only has a few dogs there but really mine play with each other and have shown no interest in other dogs except when they "invade" our house. Even then they go MEH after a few minutes. When we are out for walks they stand still and let other dogs sniff them, not so much sniffing back and no tail wagging. But at least they are not afraid just "OK can we go nowish". I think things can get out of hand at a dog park, their often are messes left in the grass and a perfect place for viruses..
