Genuine Drontal By Bayer Wormer for dogs. This normally requires a prescription from a veterinarian and is the BEST and SAFEST wormer around, effective against all 4 kinds of intestinal worms (including tapeworm, roundworms, hookwhorms, and whipworms.) I will send complete instructions with your order. Each tablet treats up to a 22 pound dog. If you are interested in ordering Drontal from me it will ship for FREE anywhere in the USA. Just let me know how many tablets you need. Pricing for 1 tablet $9.99, 2 tablets $15.99 or 4 tablets $29.99. I am a Power Seller on ebay with excellent credentials. Unfortunatley I am no longer allowed to sell this product on ebay because of prescription required and I have a lot of stock left. Tablets are SEALED AND FRESH. Payment must be made in advance by check or Pay pal. Thank you.
