Interceptor Spectrum Chewables for Very Small Dogs Up to 8.8 lbs (Up to 4 kg) (Orange)

Interceptor Spectrum Chewables for Very Small Dogs Up to 8.8 lbs (Up to 4 kg) — one chicken-flavoured monthly chew that prevents heartworm and treats roundworm, hookworm, whipworm and tapeworm. Made by Elanco (also sold as Interceptor Plus in the USA and Canada). APVMA-registered in Australia, where it's legally available without a vet prescription. Ships USA, Canada and worldwide — no vet prescription required.

5-in-1 monthly protection — heartworm plus every major intestinal worm

Interceptor Spectrum is one of the most complete monthly wormers on the market. A single chicken-flavoured chew prevents heartworm disease and treats all four of the intestinal worms that cause the most damage in very small dogs: roundworm, hookworm, whipworm and tapeworm. That replaces three separate products with one chew — one prescription-free, vet-grade dose every 30 days.

The combination of milbemycin oxime and praziquantel makes Interceptor Spectrum a smart, simple way to handle internal parasites in one go. The only thing it doesn't do is fleas and ticks — which is by design, because the strongest flea-and-tick chews on the market work best when paired with a dedicated heartworm/wormer rather than rolled into one tablet.

Sized specifically for very small dogs Up to 8.8 lbs

The Orange pack of Interceptor Spectrum is dosed for very small dogs in the Up to 8.8 lbs (Up to 4 kg) weight band. That covers most Chihuahuas, Yorkshire Terriers, Maltese, Toy Poodles, Pomeranians, Papillons, Affenpinschers and other toy and very small breeds. Weigh your dog before each refill to make sure they're still in the right band — underdosing reduces efficacy, especially against heartworm.

What Interceptor Spectrum protects against

• Heartworm (Dirofilaria immitis) — prevents the larvae transmitted by mosquito bites from developing into adult heartworms. The single most important monthly dose for any dog living in a heartworm-endemic region.
• Roundworms (Toxocara canis, Toxascaris leonina) — including the immature stages most wormers miss.
• Hookworms (Ancylostoma caninum, Uncinaria stenocephala) — responsible for blood loss and anaemia in young puppies.
• Whipworms (Trichuris vulpis) — one of the hardest intestinal worms to clear in adult dogs.
• Tapeworms (Dipylidium caninum, Taenia species, Echinococcus granulosus / hydatid tapeworm) — including the flea-transmitted tapeworm and the public-health-critical hydatid tapeworm.

How Interceptor Spectrum works

The active ingredients are milbemycin oxime (the heartworm preventative and roundworm/hookworm/whipworm treatment) and praziquantel (the gold-standard tapeworm treatment). When your dog eats the chew, the actives are absorbed into the bloodstream and gut, where they kill heartworm larvae before they can mature, and kill adult intestinal worms before they can lay eggs.

Because the actives clear from the body within a few days, monthly dosing is essential. Missing a dose creates a gap in heartworm cover that's the biggest risk in a year-round flea/tick/wormer routine.

How to give Interceptor Spectrum

• Give one Orange chew once every 30 days, year-round in regions with year-round mosquito and worm activity
• Most dogs eat the chew like a treat — give by hand, in a bowl or hidden in soft food
• Best given with or just after a meal — improves absorption of milbemycin oxime
• Mark the same date each month on your calendar; consistency is what keeps heartworm cover unbroken
• If you miss a dose by more than 8 weeks, talk to your vet — a heartworm test before resuming dosing is sometimes recommended

Why owners choose Interceptor Spectrum

• 5 parasites in one chew — heartworm plus all four major intestinal worms in a single chicken-flavoured tablet
• No prescription needed on smartwaypetsupplies.com — sold over the counter to the USA, Canada and worldwide
• Same active combination as the US/Canada product sold as Interceptor Plus (Elanco)
• Chicken-flavoured oral chew rather than a topical — no greasy residue, won't wash off, safer around children and other pets
• Wide safety margin — approved for puppies from 6 weeks of age and at least 2 lbs (1 kg)
• Cleaner pairing with long-duration flea/tick chews like Bravecto (12-week protection) than combo all-in-ones

Pack options

• 3 Pack — three months of cover
• 6 Pack — six months of cover; the best value per dose and the most popular choice for owners who dose year-round

For full year-round protection you need 12 chews per year. Two 6-packs cover a full year and work out significantly cheaper per dose than four 3-packs.

Active ingredients

Milbemycin oxime and praziquantel. Each Interceptor Spectrum Orange chew is dosed to the Up to 8.8 lbs (Up to 4 kg) weight band. Strength details are on the manufacturer's leaflet inside every pack.

Safety and side effects

Interceptor Spectrum has a wide safety margin and is well-tolerated in dogs from 6 weeks of age and at least 2 lbs (1 kg) bodyweight. The most common side effects, when they occur at all, are mild and short-lived — reduced appetite, mild lethargy or soft stool in the 24 hours after dosing. Talk to your vet before use if your dog has a history of seizures or is being used for breeding. Safe to combine with flea/tick chews like NexGard and Bravecto and with any topical flea/tick product. Do not give to cats — they need a cat-specific monthly wormer and heartworm preventative.

What Interceptor Spectrum doesn't cover

Interceptor Spectrum prevents heartworm and treats intestinal worms only. It does not kill fleas or ticks. For complete year-round parasite protection, pair Interceptor Spectrum with a monthly flea and tick product:

• 12-week flea and tick chew — a 12-week Bravecto chew every 3 months (4 doses per year) is the most convenient pairing
• Monthly flea and tick chew — NexGard or Simparica every 30 days, given on the same date as Interceptor Spectrum

If you'd rather a single all-in-one tablet that covers fleas, ticks, heartworm and worms in one chew, NexGard Spectra and Simparica Trio are both options — though many vets prefer the Interceptor Spectrum + Bravecto pairing because each product is best-in-class at what it does.
