Heartworm, Worming and Flea Spot-On for Large Dogs

Overview
PURINA Totalcare® Heartworm, Worming & Flea Spot-On Protection for Large Breeds is a topical, all-in-one parasite treatment designed specifically for large dogs. The formulation combines imidacloprid and moxidectin, providing coverage against fleas, heartworm and common intestinal worms in a single monthly application.
Imidacloprid acts on contact to kill adult fleas and larvae, helping break the flea lifecycle, while moxidectin works systemically to prevent heartworm disease and treat intestinal worms such as roundworms, hookworms and whipworms. The liquid is applied directly to the skin as a simple spot-on dose.
This product offers a convenient multi-parasite protection option for large-breed dogs and forms part of the PURINA® TOTALCARE® parasite-management range.
