Aggressive Border Collie
(Allentown, PA )
My boy is 2 1/2. He recently started acting aggressively towards my son (30). We live in the same house and he has always been with him My son is the one that brought him home. I am the one he is always with though. 4 times in the last month and a half, my dog has gone after him. Jumping up, barking, growling and snapping at him. He hasn't bitten yet. It is always when I am around. He barks when someone gets close to my bedroom door also. My son says when I am not there he is normal. I have had him to the vet to check for medical reasons. I have also had someone come to the house. He suggests that he is assertive, not aggressive. I am not so sure. I am looking for any answers to help him be the happy dog that he was 2 months ago. Side note, my hours changed and I am not home as much as I used to be. I am not sure if this is contributing to his behavior.
