Its an animo acid. Its the main ingredient ( actually I think the ONLY ingredient ) in a supplement that a vet sells at a behavior clinic that I took Gibby to for fitting of a Thunder Shirt. They sell it for dogs in a liver base for $40 for about 2 days worth..then a generic brand for half the price. I looked it up and it sounds worth trying.
The holistic vet that I took Gibby to last year suggested a natural supplement that might have been the exact same thing but I dont' have it written down to see for sure.
I wondered if anyone ever heard or tried it?
