Growly American bull dog
So my 4 month old American bulldog has growled at three people, picking him up when he is tired or sleeping. First he lunged and growled at a friend when she tried to pick him up to move him closer to her on her couch. Then I was running out of the house and he was sleeping on the couch, when I went to pick him up to move him in with my boyfriend he growled. Last night my boyfriend tried to move him off the couch to sit down and he growled he didn't lung at either of us just let out a growl. Now is this some claim over the couch? He gets lots of exercise and also goes for a day at the bark park (doggy daycare) a week. I have grabbed his muzzle and said NO very firmly. i have made him get off the couch and I have pinned him. Anyone have any suggestions to help me help him pass this growly attitude before it leads to something worse.
