Keep your large dog protected all month long with Simparica — the fast-acting, liver-flavoured monthly chewable for dogs 44.1–88 lbs (identified by the green packaging).

Starts Working Fast

Simparica begins killing fleas within 3 hours and ticks within 8 hours of the first dose — and keeps working for a full 35 days.

Broad Parasite Coverage

Each chewable protects against:

• Fleas (kills before they can lay eggs, breaking the lifecycle)
• 5 species of ticks — including American dog tick, black-legged (deer) tick, Gulf Coast tick, Lone Star tick, and brown dog tick
• Demodex mange mites and sarcoptic mange (scabies)

Why Dog Owners Love Simparica

Simparica is a liver-flavoured, soft chewable that most dogs take willingly — no hiding pills in food. It's given once monthly, making it easy to stay on schedule. For owners of large breeds, having a single reliable chewable that covers the full spectrum of common parasites keeps protection simple and consistent.

Frequently Asked Questions

How Quickly Does Simparica Start Working?

Simparica starts killing fleas within 3 hours and ticks within 8 hours of the first dose. It continues providing full protection for 35 days.

Is Simparica the Same as Simparica Trio?

No. Simparica contains sarolaner only and protects against fleas, ticks, and mange mites. Simparica Trio also contains moxidectin and pyrantel, adding protection against heartworm, roundworm, and hookworm. If you need all-in-one coverage, consider Simparica Trio instead.

Do I Need a Prescription to Buy Simparica from Smartway?

No. Smartway Pet Supplies ships genuine Simparica from Australia, where it can be legally supplied without a prescription. No vet visit or prescription upload is required to place your order.

Is the Green Pack the Right Size for My Dog?

The green pack is designed for dogs weighing 44.1–88 lbs (20–40 kg). If your dog is at the lower or upper edge of this range, check our other Simparica variants to ensure the best fit for their weight.

Can Simparica Be Given With Food?

Simparica can be given with or without food. Most dogs accept it readily on its own due to its liver flavour, but giving it with a small meal is perfectly fine if preferred.

How Often Should I Give Simparica?

Simparica is given once every 35 days (approximately monthly). For best results, try to give it on the same date each month to maintain consistent protection.

Is Simparica Safe for Large Dogs?

Simparica is approved for use in dogs 6 months of age and older. The green pack is specifically formulated with the correct sarolaner dose for dogs 44.1–88 lbs, ensuring your large breed receives accurate, effective protection. Dogs with a history of seizures should only use Simparica under veterinary guidance, as sarolaner belongs to the isoxazoline class which has been associated with neurological events in rare cases.
