Neo is really a great dog. He loves all people, kids, has never once shown aggression towards people. Over the last several months he has started to be territorial and it has turned into latching on neck dog fights. Hard to get apart. Triggers at first were toys, or my one dog growling. Then when they were separated he turned on my other male when they got excited or barking. Seems anxiety driven or commotion. The last fight was no the same trigger and that’s what made us come to this decision. It’s been 6 months of fights, separation, training, trying to figure it out but now that I can’t see the triggers, I don’t know how to keep them safe.
