My name is Baci!

I took in Baci around a year and a half ago from his previous owners who mistreated and neglected him. When I received him his nails and fur were fully grown out and matted. He looked like he had never been cared for.
He is a good dog but unfortunately due to the neglect and mistreatment from his previous owners, Baci has behavioral issues. He obsessively barks at noises when he is outside in the yard and also will bark obsessively at people. The most serious issue he has is that he is prone to aggressive behavior from time to time. There are two main scenarios in which he will be aggressive: 1. he is very territorial with his food and will bite another dog or person if they try to take his food away from him. 2. He is aggressive towards people he doesn't know especially if they come to the house. He may even bite them.
I believe that the best match for him would be to be adopted into a household with no children or other pets. I think his behavioral issues can be fixed with training.
