NexGard Spectra – A Broad Spectrum Treatment for Dogs

NexGard Spectra is an advanced treatment for controlling fleas and ticks on dogs. The highly palatable beef-flavored chew also treats and prevents gastrointestinal worm infestations. The oral treatment controls flea infestations in dogs for 5 weeks and ticks infestations for 4 weeks. It rapidly kills fleas as well as ticks, including brown dog ticks, bush ticks, and the deadly paralysis ticks. NexGard Spectra also kills various mites and controls demodectic mange (caused by Demodex spp.), sarcoptic mange (caused by Sarcoptic mites), and otodectic mange (caused by ear mites). Moreover, NexGard Spectra is also effective in the prevention of heartworm disease with a regular monthly dosage. This all-in-one tasty chew also controls mites and prevents flea tapeworm infestations by controlling ticks.

How does NexGard Spectra work?

NexGard Spectra is a new way of treating flea and tick infestations in dogs. Its active ingredients kill fleas before they lay eggs and treat other common parasites quickly. One of its key ingredients - Afoxolaner directly attacks nerve cells, resulting in paralysis and eventually killing them. The rapid action of Afoxolaner kills fleas preventing the maturation of immature stages of tapeworms and thus controlling flea tapeworm infestations. The other ingredient, Milbemycin oxime, kills parasites like nematodes that live inside the body of animals. Nexgard Spectra is recommended for dogs and puppies from 8 weeks of age, providing they weigh at least 4.4 lbs.

Important Note: Please consult your vet before buying this product. Dogs with a history of seizure should only be treated after consulting a vet.
