    Good Heartworm medication
    I am pleased that your pharmacy still had this product available when I ordered; unfortunately now that I need to order again for my other greyhound, it is no longer available, on backorder with no known date regarding when it will be back in stock. Price of this medication was reasonable (had a promotional code for 12% off), my vet was contacted promptly for prescription approval, and free shipping was fast. Product arrived in good condition and as described. Iverhart Max not only prevents heartworm, it also treats and controls Roundworms, Hookworms, and TAPEWORMS! I would definitely order again from this pharmacy if only it was available!!!
    ProsTreats and controls roundworms, hookworms and tapeworms as well as preventing heartworm disease.
