I don't knnow what to tell you, I always tried to have Pepper used to being around dogs different sizes, and up to recently, he LOVED all dogs, all of them. He used to go to a doggie daycare and doggie parks, all that socialization and what? He's 1.5 years and starts getting aggressive towards some dogs. I have to pick him up sometimes as he goes into an attack mode, and usually it is towards big dogs. He always loved bigger dogs and nothing bad ever happened when he was around dogs... He was always ready to run to them friendly and tail-wagging. Now, I don't know what that new behavior is about... |
