 Disobedience and aggression sometimes can be fixed, sometimes not. When people come to me with dogs that are resource garters, that's genetic. There is a 40% chance I'm going to say I can work that out. 60% chance I cannot. The dog needs to be put down, not rehomed, put down. If a dog is a resource garter of food, he's going to resource guard his toys, and he's going to start resource guarding people.
