Nexgard spectra protects from Ticks, Fleas, Heartworm, Roundworms, Hookworms and Whipworms. We strongly recommend consulting with your vet to determine the most suitable options for your pet's specific needs as this may vary for each animal, health condition, and any potential allergies.
As with all heartworm medications, this is a preventative measure and it is important that your dog is first tested for existing heartworm.
