NexGard Spectra Green Pack is recommended for medium dogs of age 8 weeks and older and weighing between 16.5 and 33 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 Medium Dogs also prevent deadly heartworm disease and aids in the control of flea allergy dermatitis.
NexGard Spectra Green 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.

I see very different prices for Nexgard Plus (U.S.) and Nexgard Spectra (this site), but both claim to tackle fleas, ticks, heartworm. What is the difference?
Nexgard Plus contains afoxolaner, moxidectin, and pyrantel and protects against fleas and ticks, prevents heartworm disease, and treats and controls roundworms and hookworms. Nexgard Spectra contains afoxolaner & milbemycin oxime and protects against fleas, ticks, mites, intestinal worms and preventing heartworm disease, lungworm and eyeworm infections.
Are prices in Canadian funds? What's the difference between Nexgard Plus or Nexgard Spectra? Do you ship to Ontario Canada? My dog got a prescription Vet wrote letter in date July 11, 2023 .Can I go ahead order a NexGard Spectra for my dog?
