We would never recommend this product, OR THIS COMPANY. If we could have rated it a 0, we would have. Our dog had many side effects, and after many phone calls, e-mails and long waits in between, for way over a week, they still haven’ t said that they will send us a refund. They state, 100% SATISFACTION GUARANTEED. IF YOU ARE UNHAPPY FOR ANY REASON, LET US KNOW AND WE’LL ISSUE A FULL REFUND. WE HAVE DONE THAT, AND NO REFUND. HOPEFULLY THEY WILL SEND US A CHECK FOR THE $28.88, THAT WE WASTED ON THIS PRODUCT. BEWARE OF THEIR GUARANTEES!
