NexGard Spectra Chewables for Extra Small Dogs 4.4–7.7 lbs (2–3.5 kg) – Flea, Tick & Heartworm Prevention (Orange)

NexGard Spectra Chewables for Extra Small Dogs deliver complete monthly parasite protection in a single beef-flavored chew. Combining afoxolaner and milbemycin oxime, NexGard Spectra (Orange) protects extra small dogs weighing 4.4–7.7 lbs (2–3.5 kg) against fleas, ticks, heartworm, and the most common intestinal worms (roundworm, hookworm, and whipworm) — six parasites covered with one chew, once a month.

What NexGard Spectra Protects Against

• Fleas: Kills adult fleas before they reproduce, breaking the flea life cycle.
• Ticks: Controls multiple species including black-legged (deer), American dog, lone star, and brown dog ticks.
• Heartworm: Prevents heartworm disease (transmitted by infected mosquitoes).
• Roundworm, hookworm, and whipworm: Treats the three most common intestinal worms in dogs.

Why Extra-Small-Dog Owners Choose NexGard Spectra

• All-in-one protection: Replaces 2–3 separate products — one chew, six parasites covered.
• Once a month: One beef-flavored chew on the same date each month.
• No greasy topicals: Bathe, swim, and snuggle right after dosing.
• Tiny-dog friendly: The Orange pack is dosed specifically for dogs 4.4–7.7 lbs — never substitute or split doses.
• Puppy-safe from 8 weeks (minimum 4.4 lbs / 2 kg).

How NexGard Spectra Works

NexGard Spectra combines two trusted active ingredients:

• Afoxolaner is absorbed into your dog’s bloodstream and kills fleas and ticks when they bite. Because it works systemically, parasites can’t hide in fur or hard-to-reach spots.
• Milbemycin oxime eliminates immature heartworm larvae and treats adult intestinal worms, stopping heartworm disease before it can establish and clearing common worm infections.

Who It’s For

• Extra small dogs weighing 4.4–7.7 lbs (2–3.5 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 chew per month, on the same date each month.
2. Offer directly as a treat, or with food — either works.
3. Make sure your dog chews and swallows the full dose.
4. Year-round dosing is essential for continuous heartworm prevention — gaps in coverage can let larvae mature.

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 or seems unusual.

Frequently Asked Questions

My puppy is small — when can she start NexGard Spectra Orange?
NexGard Spectra Orange is approved for puppies from 8 weeks of age, as long as they weigh at least 4.4 lbs (2 kg). Don’t start it on younger or lighter puppies.

My puppy is growing fast — when do I move from Orange to Yellow?
Switch to the Yellow pack (7.8–16.5 lbs) as soon as your puppy crosses 7.7 lbs. Underdosing a dog who’s outgrown a pack reduces effectiveness, especially for the heartworm component.

What’s the difference between NexGard and NexGard Spectra Orange?
Regular NexGard covers fleas and ticks only. NexGard Spectra adds heartworm prevention plus treatment for roundworm, hookworm, and whipworm — so one chew replaces 2–3 separate products.

Does my dog still need a separate heartworm test before starting?
For puppies starting NexGard Spectra before 7 months of age, no test is typically needed. For older dogs being newly started on heartworm prevention, your vet may recommend a heartworm test first — standard practice across the US and Canada.

How fast does NexGard Spectra start working?
Fleas start dying within hours, and ticks are killed within 24–48 hours. Heartworm and intestinal worm protection builds with consistent monthly dosing.

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 at checkout.
