dog-dog, dog-human, territorial aggressive American Foxhound
Rescue dog, American Foxhound w/boxer mix (DNA test by vet), sometimes growls at other dogs wanting to attack, growls sometimes at humans even while on leash. Recently charged and cornered a woman, barking and growling while off leash. A few days later while on leash, the dog nipped at a woman standing there talking to my wife who was holding the dog. Did not break skin but bruised leg. Not the first time dog nipped at someone. Dog is protective of us and our property. What are our options, or should we have the dog put down?
