NexGard Spectra Purple Pack is recommended for large dogs of age 8 weeks and older and weighing between 33 and 66 lbs.
NexGard Spectra is a monthly chewable treatment that provides complete protection against fleas, ticks, heartworms, and intestinal worms like roundworms, whipworms, and hookworms, in a single tasty beef-flavored chew. It rapidly kills fleas and ticks, including brown dog ticks, bush ticks, and the deadly paralysis ticks. The active ingredient kills various mites and controls demodectic mange (caused by Demodex spp.), sarcoptic mange (caused by Sarcoptic mites), and otodectic mange (caused by ear mites). This all-in-one treatment also prevents flea tapeworm infestations by rapidly killing fleas. NexGard Spectra for Large Dogs also prevent deadly heartworm disease and aids in the control of flea allergy dermatitis.
NexGard Spectra Purple is highly effective against the most problematic parasites that infect dogs. It is formulated with two key ingredients: Afoxolaner and Milbemycin oxime. Afoxolaner kills fleas within 8 hours of administration by over-stimulating their nervous systems. On the other hand, Milbemycin oxime is a broad-spectrum antiparasitic. It is an anthelmintic (acts against intestinal worms) as well as a miticide (kills various mites spp.) The joint action of Afoxolaner and Milbemycin oxime protects dogs from various disease-causing internal and external parasites when given regularly every month.
Important Note: Please consult your vet before buying this product. Dogs with a history of seizure should only be treated after consulting a vet.

Does pack each come with afoxolaner 75mg and other 15mg total 90mg? Should I give flea & tick in the fall & winter months in KY? Can a chew be divided for more than one dog according to weight? I buy NexGard Spectra from the vet in Canada for my two dogs, but the NexGard Spectra that we use also includes protection from Lyme disease (6 in 1 treatment). Do you sell those NexGard Spectra tablets also? Hello, I am confused. I've ordered 2 boxes of 6 pack but received 3 boxes of 3 packs? 3 items inside 1 box. Should be 2 boxes with 6 packs of supplement inside each box?
