NexGard Spectra Chewables for Small Dogs 7.8–16.5 lbs (3.6–7.5 kg) – Yellow

NexGard Spectra Chewables for Small Dogs 7.8–16.5 lbs (3.6–7.5 kg) – Flea, Tick & Heartworm Prevention (Yellow)

NexGard Spectra Chewables for Small Dogs deliver complete monthly parasite protection in a single beef-flavored chew. Combining afoxolaner and milbemycin oxime, NexGard Spectra (Yellow) protects small dogs weighing 7.8–16.5 lbs (3.6–7.5 kg) against fleas, ticks, heartworm, and the most common intestinal worms — six parasites covered with one chew, once a month.

What NexGard Spectra Protects Against

• Fleas: Kills adult fleas fast, before they reproduce and infest your home.
• Ticks: Controls black-legged (deer) ticks, American dog ticks, lone star ticks, and brown dog ticks.
• Heartworm: Prevents heartworm disease transmitted by mosquitoes.
• Roundworm, hookworm, and whipworm: Treats the three most common intestinal worms in dogs.

Why Small-Dog Owners Choose NexGard Spectra

• One product, full coverage: Replaces a separate flea/tick chew + heartworm preventative + wormer.
• Monthly chew: Easy to remember, easy to give — same date each month.
• Tasty, soft texture: Most small dogs accept it as a treat.
• No mess: No topical residue, no greasy patches, no waiting before petting or bathing.
• Sized for small dogs: The Yellow pack is dosed for 7.8–16.5 lbs — never share doses across sizes.

How NexGard Spectra Works

NexGard Spectra combines two complementary active ingredients:

• Afoxolaner works systemically from your dog’s bloodstream — fleas and ticks ingest it when they bite and are killed before they can transmit disease.
• Milbemycin oxime kills immature heartworm larvae and clears adult intestinal worm infections, providing broad parasite control in one dose.

Who It’s For

• Small dogs weighing 7.8–16.5 lbs (3.6–7.5 kg)
• Puppies and adult dogs 8 weeks of age and older
• Healthy dogs without a history of seizures (consult your vet if your dog has a seizure history)

How to Give NexGard Spectra

1. Give one Yellow chew per month, on the same date each month.
2. Offer directly as a treat, or with food.
3. Make sure your dog chews and swallows the full dose.
4. Year-round dosing is essential — missed months can leave gaps in heartworm protection.

Possible Side Effects

NexGard Spectra is well tolerated by most dogs. Mild, short-lived side effects can include vomiting, diarrhea, itching, lethargy, or reduced appetite. Contact your veterinarian if anything persists.

Frequently Asked Questions

My dog is between 16 and 18 lbs — should I use Yellow or Green?
At the upper boundary, size up. If your dog weighs 16.6 lbs or more, choose the Green pack (16.6–33 lbs). NexGard Spectra is dosed effectively at the low end of each band, so moving up doesn’t harm your dog — it just ensures full coverage.

Does Yellow cover heartworm, or do I need a separate preventative?
Yellow covers heartworm prevention. You don’t need a separate heartworm preventative — that’s the whole point of choosing NexGard Spectra over regular NexGard.

How is NexGard Spectra different from regular NexGard?
Regular NexGard covers fleas and ticks. NexGard Spectra adds heartworm prevention plus three common intestinal worms (roundworm, hookworm, whipworm) using a second active ingredient (milbemycin oxime). One chew, six parasites covered.

Can I switch from a topical to NexGard Spectra?
Yes — you can switch directly on your next dosing date. Give the NexGard Spectra chew on the day your topical would have been applied. No washout period needed.

Do I need a prescription to buy NexGard Spectra?
No — SmartWay Pet Supplies ships NexGard Spectra over the counter to customers across the US and Canada. No prescription or vet authorization required.

Should I dose year-round?
Yes — year-round dosing is recommended for both flea/tick control and continuous heartworm prevention. Mosquitoes (the heartworm vector) are active in most US/Canada regions for more of the year than people realize, and missing doses can leave dangerous gaps.
