Two year old basset-lab mix
We adopted our Bassett-Labrador mix dog, Sirius, from a shelter in Ohio when he was approx 5 months old. As he has grown, he has begun to display more drastic traits of aggression and dominance towards everyone in the house (from our 4 year old cat, my 4 kids, myself, and husband). It can be triggered by the cat or the older kids rough housing, to a boisterous conversation. It has become increasingly difficult to diffuse him in these situations. He has gone from nipping gently to full on biting if being told to chill out.
Any information you an give me on how to correct it would be most greatly appreciated. Thank you
