Hi all! So i have an almost 3 year old OEB named Easten. I love him rediculously! The past 8 months or so he started oit of nowhere becoming aggressive. He bite my neighbor , mailman, vet, now my son! Its weird because he can be around 30 plus people at times and never bite anyone. It seems to be when someone abruptly shows up , rings my doorbell, or walks up to him. I have 4 sons and i am at the point that i fear leaving him out in the house when people come over. Most of the time he is the sweetest dog its the weirdest thing. He has had numerous ear infections over the years and of course they were treated. I took him to the vet, and they suggested him having surgery to take out his ear canals due to scar tissue build up and that he may just not feel good because of that. The surgery is over 5K! Yikes. Any suggestions? It seems to me a dominance aggression. Just odd it started out of nowhere....at a loss....
