Sentinal Spectrum for Dogs – Heartworm Treatment

Sentinel Spectrum is a potent monthly dewormer treatment for dogs.  It controls heartworm infection by eliminating the immature heartworm parasites.  These tasty chews provide protection against all three parasite groups of heartworms, fleas and intestinal worms including roundworm, whipworm, hookworm and tapeworm. It also helps to protect and control flea infestations and flea allergy dermatitis in dogs by preventing the development of flea eggs and larvae and currently it does not kill adult fleas. One tasty chew monthly all year round is all it takes to protect your dog and puppies against nasty parasites. It is safe for dogs and puppies 6 weeks of age and older and weighing 2 pounds or more.
