The pack features a purple color and contains chewable tablets formulated with the combination of potent active ingredients; afoxolaner and milbemycin oxime. This formulation provides comprehensive protection against flea and tick infestations, heartworm disease, mites, and various worm infections such as roundworms, hookworms, whipworms, eyeworm, and lungworm, ensuring your large-sized canine friend remains healthy and parasite-free. The oral chewable tablet is effective for a whole month and it is safe to be given to dogs and puppies from 8 weeks of age, weighing at least 4 lbs.
