why is our dog attacking our puppy out of nowhere?
We have an 11 month old male pit and a 10 week old female mastiff. He gets along with her and is very gentle with her . He will be licking her face and playing with her very gently. It seems as though a switch just turns off in his head or something. They both will go to run to the yard and without warning he will pick her up and try to start shaking her like a rag doll. There is no growling, barking, or showing of teeth. He doesn’t tense up beforehand, it comes out of nowhere. I am at a loss for why this is happening because even when he does see her he never growls or gets aggressive.
