Hi there, I have a 12 week old male Cockapoo and his biting is terrible, he has drawn blood numerous times and he cannot settle in the living room in the evening - he gets what appears to be aggressive, sometimes lunging / barking / pouncing and hard bites. Tonight he gripped my poor Mum’s arm and wouldn’t let go - created a really deep bite and drew blood. Then when I try to pick him up he hides under a table and I have to put a treat on the floor just to lift him up whereby he thrashes around and really tries to bite me loads (but no the nipping type, actual bites) until I put him into his pen for a time out. Sometimes I have to hold him in a headlock! I’ve never ever been aggressive towards him. I’m worried he’s becoming aggressive (it’s definitely worse in the evening - he’s fine in the day - apart from the nipping). Any help would be massively appreciated - it’s my first pup!
