NexGard Spectra Chewables for Dogs – Flea, Tick, Worm & Heartworm Protection
NexGard Spectra for Dogs is an all-in-one monthly chew designed to provide comprehensive parasite protection in a single, convenient dose. This beef-flavored chew combines powerful ingredients to protect against fleas, ticks, mites, mange, heartworm, and intestinal worms, simplifying your dog’s care routine.
It kills adult fleas and controls ticks, including paralysis ticks and brown dog ticks, while also supporting protection against internal parasites. Suitable for dogs and puppies from 8 weeks of age weighing at least 4.4 lbs, NexGard Spectra offers reliable, broad-spectrum coverage with monthly use.
Why It Stands Out
- All-in-one monthly protection against multiple parasites
- Covers fleas, ticks, mites, heartworm, and intestinal worms
- Beef-flavored chew for easy administration
- Starts killing fleas within approximately 6–8 hours
- Helps control flea allergy dermatitis
- Helps prevent flea tapeworm infestations by killing adult fleas
- Controls mange and ear mite infestations
- Suitable for breeding, pregnant, and lactating female dogs (consult vet for males)
- Simplifies parasite care with a single monthly dose
What It Covers
- Fleas – kills adult fleas and helps prevent infestations
- Ticks – controls ticks including paralysis ticks and brown dog ticks
- Mites & Mange – treats and controls demodectic and sarcoptic mange and ear mites
- Heartworms – prevents heartworm disease
- Intestinal worms – treats and controls roundworms, hookworms, and whipworms
Helps reduce the risk of flea tapeworm infestations and flea allergy dermatitis by killing adult fleas that may carry tapeworms.
How the Formula Works
NexGard Spectra combines afoxolaner and milbemycin oxime to deliver comprehensive protection. Afoxolaner targets fleas and ticks by affecting their nervous system, while milbemycin oxime helps prevent heartworm disease and treats intestinal worms.
This dual-action formula works systemically to provide broad-spectrum protection, helping eliminate parasites quickly and maintain consistent monthly coverage.

Much easier to administerLet's face it. In today's world of dog meds, there are many good options. But getting them down your dog's throat and having them stay there are another thing. I was using Simparica Trio for a couple of years but had a lot of trouble with my 55 lb dog taking the very large Simparica Trio tablet. I wrapped it in cheese, I wrapped it in Ham slices, etc. and almost every time he would spit it out or a major portion of it. It was always an adventure getting him to take it all. But then I ran across this Nexgard Spectra, the tablet was MUCH smaller and he takes it in one fast swallow wrapped in cheese. Thank you Lord! And by the way, it works great too. We live with woods all around us with lots of wildlife, so there are ticks and fleas, but every tick I find on him is already dead, just as it was with the Simparica Trio. So, give yourself a break and buy this instead, it's much easier to give due to the smaller tablet size..
