I've got one dog that shivers when fireworks go off and the GSD wasn't here last July, so I looked for something to relax them for the 4th and found this stuff:
It intrigued me because of the hemp ingredient. The content is low according to the company at 0.3%, but there's several other ingredients. Anyway, it worked great. They don't like trips to the vet, so I'll use it for that in the future, too.
I give them all the Cosequin with MSM & HA as well, in an attempt to keep the joints healthy.
