Good morning Pawbly friends-
Having a sudden – very sudden- change in behavior in one of our GSDs. We are trying to think back to figure if there has been any change in routine that might cause this. It is strange- Rontu will start to give a high grumble or start to “talk” now when you approach him, or his bed or his bone or his food. This morning just now, he did that with Butch (one of our others) when he came to me to get a head scratch. We promptly put Rontu in a sit and then told him “bed” which he went to a did lie down. We are going back to square one training and positive reinforcement. My thinking is that this not nipped in the bud right away will lead to full blown food aggression and possession issues, which we do not want. Any other advice would be GREATLY appreciated. Thanks!!
