“Good value and a very safe wormer that eradicates every worm exposure around my area except heart-worm. My vet states that I can start to administer Panacur to puppies at 3 weeks of age and the dam once a month thru gestation and along with the pups post whelp. I give Panacur monthly to all my dogs and once a year I administer Panacur 3 days in a row to to insure that all worms, eggs, etc, are eradicated. My dogs are strong and never get sick. NO WORMS = Health Dogs”
