Do you guarantee your product? What I mean by this is I have spoken to my vet and they told me that the product is not guaranteed by the manufacturer if it is not purchased from the vet. I am also aware that if my pet were to get heartworms that Merial will pay for the treatment only if I purchase it from a licensed vet. I spoke to both Merial and my vet this AM. Please advise. I do not see any guarantee on your site for this type of product.
