Hello all I’m new and in need of a lot of help. I have a 1 year old golden retriever Loon and we just got a 9 week old golden puppy Moose. Loon is very high strung and very much still a puppy. Loon is jealous of Moose and we are trying to stop it. Loon will steal Moose’s treats and run away leaving Moose empty handed. At first moose didn’t mind as he’s a puppy and he has other things on his mind. But today when I went to pet Moose he growled at me for the first time. He had a yummy chew in his mouth and was not going to let anyone steal it. That was the first incident and I need help stopping resource guarding before it escalates. As of now we have not been keeping Loon and Moose separate entirely just supervised play and eat and separate areas for sleep. Please help!!!
