That's so cool I didn't realize you were a vet. You know the dog I reference in this with food aggression a behavioralist thought might be saved but the vet I've known and used to work with disagreed as did another vet because they said the threat was too severe. It was one of the most heartbreaking things I've ever been involved with. He was the sweetest puppy and as he got older the aggression became more threatening because of his size. It was such a Jekyll and Hyde situation. Sweetest animal morphed into a savage and would have destroyed anything or anyone who walked near a food source. It escalated when the kids couldn't eat in front of him. It grew beyond his own food source. It was truly tragic.
