So are you saying that if you have two well behaved "Stable" dogs that they should never be allowed to just romp and play and run around together? I'm not talking at the dog park, I hate dog parks but that's a whole other topic I'm saying like two friends that happen to have dogs and they get together in the backyard.The word "socialize" means so many different things to so many people. To me socializing dogs means my dog is over here with me, on leash and under control, and your dog is over there with you on leash and under control. Turning dogs loose at dog parks, or letting them sniff butts and noses serves no good purpose and in fact leads to major problems.
