What is in NexGard SPECTRA?

Each NexGard SPECTRA chew contains two active ingredients:

Afoxolaner, which kills fleas, ticks, mites and lice.

Milbemycin oxime, which protects against heartworm and treats common intestinal worms (roundworm, hookworm and whipworm).

Together, these ingredients provide internal and external parasite protection in a convenient monthly chew. NexGard SPECTRA can be given with or without food, and its active ingredients are rapidly absorbed to start protecting your dog from parasites quickly.

NexGard SPECTRA chews are soy-based. They are beef-flavoured but do not contain any animal proteins.

Does NexGard SPECTRA® for Dogs kill mites?

NexGard SPECTRA treats and controls three of the most common mites infesting dogs: Demodex mites (the cause of demodectic mange), Sarcoptes mites (the cause of sarcoptic mange, also know as scabies) and Otodectes, or ear mites (the cause of otodectic mange). See product label for full claim details and directions for use.

How do I treat intestinal parasites in my dog?

NexGard SPECTRA is effective against hookworm, roundworm AND whipworm, unlike some other products. It also effectively controls fleas and prevents flea tapeworm.^

Hookworm, whipworm and roundworm are a risk for all dogs as they are easily picked up from contaminated soil, sand or vegetation (like at the dog park). Some worms that affect dogs can be transmitted to people and that’s why treating your dog monthly with NexGard SPECTRA all-year-round is so important.

^By rapidly killing fleas, NexGard SPECTRA prevents flea tapeworm when used according to label. If active infection is present, a praziquantel-containing product such as ParaGard should be used.
