Welcoming a tiny pup home is pure joy—and a big responsibility. Parasites like fleas, ticks, heartworm and intestinal worms can make young dogs very sick, very fast. Simparica TRIO for Puppy 1.25–2.5 kg (Yellow) is a once-monthly chew that wraps broad protection into one easy routine. Here’s everything pet parents need to know.

What exactly is Simparica TRIO (Yellow)?

Simparica TRIO is a pork-liver–flavoured, monthly chewable combining sarolaner, moxidectin, and pyrantel. The Yellow pack is calibrated specifically for puppies weighing 1.25–2.5 kg (about 2.8–5.5 lb). Each Yellow chew contains 3 mg sarolaner, 0.06 mg moxidectin, and 12.5 mg

What it protects against (in one chew):

Heartworm disease prevention (Dirofilaria immitis)

Fleas (fast kill; helps break the life cycle)

Ticks (including paralysis tick in AU labeling)

Roundworms & hookworms (treatment and control)

Simparica TRIO is approved for dogs 8 weeks of age and older at/above the minimum weight ...
... for the size used.

How it works (the science in simple words)

Sarolaner (isoxazoline) targets flea and tick nervous systems—kills fleas quickly and ticks soon after they attach.

Moxidectin prevents heartworm disease by eliminating larval stages acquired from mosquito bites.

Pyrantel treats roundworms and hookworms present in the gut.

The U.S. prescribing information sets the minimum doses per kilogram of bodyweight delivered by any Simparica TRIO size: sarolaner 1.2 mg/kg, moxidectin 24 µg/kg, pyrantel 5 mg/kg. The Yellow chew is formulated so puppies in the 1.25–2.5 kg band receive at least these minima.

Benefits you’ll notice

One & done each month: replaces multiple separate products.

Fast flea knockdown: AU technical sheet notes action within 4–8 hours and sustained efficacy through re-infestation periods.

Tick control: includes paralysis tick (AU), brown dog tick and bush tick. (Check your country label for the exact tick species covered.)

Intestinal worm treatment: covers key roundworms & hookworms commonly seen in puppies.

Label update (US, 2025): the FDA approved a new indication: prevention of flea tapeworm (Dipylidium caninum) infections by killing vector fleas before transmission. (This is a prevention via flea control claim, not a stand-alone tapeworm treatment.)

Is the Yellow size right for my puppy?

Choose Yellow if your pup weighs 1.25–2.5 kg on dosing day. If your puppy crosses into a higher weight band as they grow, move to the next pack colour at the next dose.

Tip: Weigh monthly before dosing. Rapidly growing pups often outgrow the Yellow range.

Dosing & administration (step-by-step)

Weigh your puppy the same day.

Offer 1 chew by mouth—most pups take it like a treat. You can give with or without food; ensure the full dose is swallowed.

Repeat every 30 days, year-round, for continuous protection.

What if you miss a dose? Give it as soon as you remember and resume monthly. For heartworm prevention, consistent monthly dosing is essential.

Safety, side effects & precautions

Age/weight: Use only in pups ≥8 weeks and within the labeled weight range.

Breeding/pregnancy/lactation: safety not established—consult your vet first.

Neurologic history: Isoxazolines (e.g., sarolaner) have been associated rarely with neurologic signs in some dogs; use only as directed by your veterinarian if your pet has a seizure history.

Adverse events: In field studies, occasional vomiting, diarrhoea, lethargy or decreased appetite were reported at similar rates to control groups. Most resolved without treatment.

Human safety: Keep out of reach of children; wash hands after dosing.

Heartworm-positive pups: Speak to your veterinarian before starting any preventative.
