I have a one year old Male Akita. He has been raised with my three year old female Lab. He dominates her, and has had her by the throat over a crumb of food or a ball. In the last three weeks he has busted out my metal gate and attacked three different dogs, being walked by their owners. One attack he caused two punctures to the smaller dog! He waits and stalks these dogs if I take my eyes off him. He sometimes growls at me when I am scolding him. We have shown this beautiful dog tons of love and respect, I am at a loss. I do not want to give up on him, but he is a huge liability. What can I do? would a trainer be able to even work with this dog?
