Interceptor Tasty Dog Chews can be given to puppies from two weeks of age, and protect against heartworm. Heartworm is spread via bites from infected mosquitos, and can be life threatening and expensive to treat. In addition, Inceptor worm treatment for dogs also protects against tapeworm, and intestinal worms such as roundworm, hookworm and whipworm. Tablets can be difficult to give to dogs, but these chicken-based chews make your dog’s monthly dose much easier to manage! US-based parent company Elanco began as an animal medicine enterprise, being one of the earliest to bring antibiotics to the animal sector in 1954. R&D in successive decades has led to dedicated production of veterinary products, including the Interceptor Tasty Dog Chews worming range.
