I walk my dog early in the morning when it's still dark. Being half awake and the darkness I can't see all that's going on, or has gone on.
My dog is a blue tick hound. He was a rescue dog, and he has been to doggie day camp and I have seen him with little dogs before and he will just let them be. The people at the doggie day camp all love him and say he is a very positive influence for all the dogs, big or little. He loves almost everyone except the newspaper guy and mailman, but I think it's the smell of the paper.
When people lurk at me he is also very protective. There is a woman who walks her little dog also in the morning. My dog goes wild over this little thing. By wild I mean you would think he wanted to kill this little dog. Other little dogs have yapped at him and come very close to him but he never loses control. When he was in foster care the woman had her own little dogs. Maybe he has the same resentments he had then toward that breed of dog. I have had him close to four years and he had several quirks then. The woman is not walking by our house. Do you have any idea why he would do that?
