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.
