Aggressive four year old coccapoo
My dog seems to be very possessive about me. He usually follows me everywhere and lies near my feet when i sit on the couch. When I am in my room, he will attack anyone who enters the room. This is mostly in the evenings when he is sleeping. He has bitten and torn a few of my sons clothes. He has also ripped his hand a couple of times. usually when he attacks he seems to be not fully awake. After attacking,his jaw shakes. A few minutes after that he seems to be ashamed of his behavior and looks at my son apologetically. I am at my wits end how to fix this behavior. He also barks constantly when someone visits or when someone is walking a dog outside. We took him number of training classes as a puppy and also hired a trainer to come home and help him. They were of the opinion that he was not socialised properly by the breeder. can my dogs behavior fixed? He used to growl before attacking. Now he just jumps and attacks. Please help. Thank you.
