Your dog isn't aggressive. He's over a line.

It was never aggression. It was a threshold. Every dog has a line. Below it, he can think, learn, take food, hear you. Above it, none of it lands — the thinking part of the brain is offline. That's why the training held in class and collapsed on the sidewalk. Where that line sits isn't set by training. It's set by serotonin, and 95% of your dog's serotonin is made in his gut. When gut bacteria break down, production drops and the line drops with it. CalmAxis targets the gut-brain axis directly. 500mg postbiotic metabolite blend, 100mg L-theanine, 25mg chamomile.
