Bringing a puppy home is the start of a lot of firsts — first vet visit, first vaccination, first lead walk. Choosing the first parasite-protection routine is one of the few firsts that compounds for the rest of their life.
In Short:
Puppies in Australia can start Advocate Ultra Chew from 8 weeks of age, provided they weigh at least 2 kg — the same single monthly chew their adult parents will eventually take.
The Extra Small variant (2–2.8 kg) is sized for very young puppies and toy breeds at the minimum weight, and most puppies move up through Small (2.8–5.5 kg) and Medium (5.5–11 kg) within a few months.
Coverage spans fleas, paralysis ticks, heartworm, mites, roundworms, hookworms and tapeworms in one chew, given with food once a month.

Why Puppies Need Parasite Protection From Day One
Puppies are born more vulnerable to parasites than adult dogs, not less. Roundworm and hookworm can pass from mother to puppy through the placenta and through milk, which means many puppies are already carrying intestinal worms before they leave the breeder. Fleas use puppies as a warm, reliable host the moment one walks past. And in heartworm-active regions, a single mosquito bite at three months old starts a slow infection that won't show symptoms until your dog is two or three years old.
This is why most Australian vets start a parasite-protection conversation at the eight-week health check, alongside the C5 vaccination and microchipping. Skipping or delaying that first treatment compounds — every month a puppy goes without protection is another opportunity for an infection that's far harder to treat than to prevent.
What to Look For in a Puppy Parasite Treatment
The right monthly product for a puppy needs three things. It needs to be safe and registered for use from a low minimum age and weight (most products kick in at 8 weeks and 2 kg, but read the label). It needs broad-spectrum coverage so you're not adding a second product within weeks. And it needs to come in a small enough size that the dose actually matches a 2.5-kg puppy, rather than being scaled down from a 10-kg minimum. A monthly chew that nails all three is a single line in your puppy diary instead of three or four.
Sizing as Your Puppy Grows
A 2.5-kg puppy starting on Extra Small (2–2.8 kg) will likely outgrow the band within weeks. Most owners buy a Single Extra Small to bridge the gap, then move to Small (2.8–5.5 kg) for the next few months and Medium (5.5–11 kg) once the puppy crosses 5.5 kg. Reweigh every monthly cycle until growth slows around 8–12 months. Toy breeds may stay on Extra Small or Small for life; large breeds will move through three or four bands before settling.
Giving the Chew to a Teething or Fussy Puppy
Most puppies eat the chew without prompting if it's offered alongside or just before a meal. If your puppy is teething or food-fussy, break the routine — try giving the chew on an empty stomach first thing in the morning, or hand-feed it as a treat after training. If they spit it out, the dose hasn't absorbed and you'll need to redose, so keep an eye until you're sure it's swallowed. Don't crush or hide the chew in something they might leave behind.
Frequently Asked Questions
At what age can puppies start Advocate Ultra Chew?
From 8 weeks of age, provided the puppy weighs at least 2 kg. Both conditions must be met — a 7-week-old puppy that already weighs 3 kg can't start yet, and a 9-week-old that hasn't reached 2 kg can't either. Talk to your vet about an interim plan if your puppy is on the edge of either threshold.
Which Advocate Ultra Chew size do I start with?
Pick the band your puppy's current weight sits inside. Most puppies start on Extra Small (2–2.8 kg) or Small (2.8–5.5 kg). Reweigh every monthly cycle and step up to the next size when your puppy crosses the boundary — never round up early, because a higher dose is calibrated for heavier dogs.
Can I give Advocate Ultra Chew alongside puppy vaccinations?
In most cases yes, but coordinate with your vet. The chew is registered for use in healthy puppies from 8 weeks, which is also the typical first-vaccination age — many Australian vets give the first chew at the same appointment. If your puppy has had a recent reaction or is unwell, your vet may stagger the doses by a few days.
How does this compare to a flea and worm treatment for puppies that uses separate products?
Most traditional puppy routines stack three or four separate products: a flea drop, a heartworm tablet, an all-wormer, and sometimes a tick collar. Advocate Ultra Chew replaces all of those with one monthly chew — covering fleas, paralysis ticks (plus bush and brown dog ticks), heartworm, mites, roundworms, hookworms and tapeworms. Fewer products to track, fewer reminders, and one calendar date to remember.
My puppy is under 2 kg — what should I do?
Wait until they hit 2 kg, and ask your vet whether a short interim treatment is needed. Some toy-breed puppies don't reach 2 kg until 10–12 weeks, and the gap can usually be managed with a vet-recommended product approved for lower weights.
Don't try to give a smaller dose of Advocate Ultra Chew — chew sizing isn't proportional, and a smaller chew is a different formulation.
How long does Advocate Ultra Chew protect a puppy for?
One full month per dose, identical to the adult schedule. Set a phone reminder so the date doesn't drift, and reweigh your puppy each cycle to check whether they're still in the right size band. If you miss a dose, give the next chew as soon as you remember and continue the monthly cycle from that new date.
