I have used the product for years! The first time on my Husky who had seizures. I am using the product now for my 12 1/2 year old Golden-Lab mix, Cassie. She was diagnosed with a large mass on each of her adrenal glands. This is causing her to pant, to have tachycardia, and to be stressed. Canna-Pet has calmed her down enough to be able to sleep and not pant as much. It’s the best product out there for my needs.
