In short
Both are Australian vet-formulated supplement brands and the real choice is format. Petz Park makes weight-dosed powders that mix into food with every active ingredient and amount printed on the label. They cover both dogs and cats. ZamiPet makes palatable clover-shaped chews fed like a treat which suit a fussy dog and need no mixing, though the chews carry grain binders and do not publish the amount of each active. Neither format is simply better. A powder is more concentrated, disclosed and grain-free, while a chew is sometimes easier to give and more portable. For disclosed doses, concentration, grain-free and cats, Petz Park. For a chew a dog takes like a treat, ZamiPet. Figures were checked on 6 July 2026.

How they differ
The core difference is the format and what it brings. Petz Park is a powder range: the supplement is a concentrated powder sprinkled onto food with no binders or fillers needed, so a higher share of each serve is active ingredient. Every product prints its amounts. It is grain-free, dosed by weight and made for both dogs and cats. ZamiPet is a chew range: the supplement is baked into a palatable clover-shaped chew of around 5g, built on ingredients like salmon, chicken, rice and wholemeal flour, which the dog eats like a treat. That format is why ZamiPet chews are easy to give but it also means the chew carries grains as binders and the active amounts are not published on the label. So Petz Park competes on disclosure, concentration, grain-free formulas and cat coverage, while ZamiPet competes on palatability, convenience and the simple pleasure of a dog taking its supplement willingly. Both are Australian-made and both describe their formulas as vet-developed.
Why choose Petz Park
A more concentrated, disclosed formula
A powder needs no binder or flavour base, so more of each serve is active ingredient and Petz Park prints the amounts on every product. A chew must include grains and flavouring to hold together, which dilutes the active share and ZamiPet does not publish the chew's amounts.
Grain-free
Petz Park's powders are grain-free and lactose-free. ZamiPet's chews are built on ingredients including rice and wholemeal flour, so for a grain-sensitive pet the powder is the simpler choice.
Covers cats too
Petz Park has a full cat range with feline-calibrated formulas. ZamiPet is primarily a dog brand, so a cat owner is served by Petz Park here.
Weight-calibrated dosing
Petz Park doses by the pet's weight in scoops, so the amount matches the animal. A chew delivers a fixed dose per chew, adjusted only by breaking it into segments.
When Petz Park is the better choice
You want to see the dose and keep it grain-free
Petz Park prints its amounts and its powders are grain-free, so you can check the dose and avoid grain binders. ZamiPet's chews carry grains and do not publish the amounts, so for disclosure and a grain-free formula Petz Park is the fit.
You have a cat or want a concentrated serve
Petz Park covers cats with feline-calibrated formulas and because a powder needs no binder, it packs more active into each serve. ZamiPet is for dogs and its active share is diluted by the chew base.
Your pet takes powder in food happily
If your dog or cat accepts a powder mixed into wet or dry food, Petz Park gives you a disclosed, concentrated, grain-free serve at a keen direct price. The powder format is then all upside.
When ZamiPet is the better choice
ZamiPet genuinely wins on format and for many dogs that is the deciding factor. Its clover-shaped chews are palatable and fed like a treat, so a dog that spits out or sniffs past a powder will often take a chew happily. The chews need no measuring or mixing, they break into segments for part-doses and they travel well, which suits a busy household or time away from home. ZamiPet is an established Australian chew brand with a solid range of dog products and a 40-day taste guarantee, so there is little risk in trying whether a dog likes them. For an owner whose main hurdle is a fussy dog or who simply wants the convenience of a treat-style supplement with no food bowl involved, ZamiPet's chew format is the stronger fit.

Cost comparison
Prices were read from each brand's own store on 6 July 2026 in AUD. Petz Park's entry supplements start around $32.95. ZamiPet's chews sit around $32.95 to $49.95 depending on the product. Both sell direct, both offer subscription or multi-pack savings and both back purchases with a 40-day guarantee.
| Pack | Petz Park supplement range | ZamiPet |
|---|---|---|
| Entry supplement price | From about $32.95 AUD | From about $32.95 AUD |
| Typical flagship product | About $34.95 for an entry pack | About $49.95 for a 60-chew tub |
| Guarantee | 40-day money-back | 40-day taste guarantee |
| Species range | Dogs and cats | Mainly dogs |
Because both price by product, the monthly cost depends on the product and pack. On comparable entry products the two are close, with Petz Park often a little lower and more concentrated per serve, while ZamiPet's value is in a chew a fussy dog will actually take.
Over a year the cost depends on the products chosen. The clearer difference is not headline price but what you get per serve: a disclosed, concentrated grain-free powder or a grain-based chew.
Petz Park scales the powder dose by weight, so a bigger dog costs more, offset by larger packs. ZamiPet scales by the number of chews. The real trade-off is format rather than size: concentration and disclosure against palatability and convenience.
Which should you choose
| Situation | Better choice | Why |
|---|---|---|
| Your dog refuses powders on food | ZamiPet | Its chews are eaten like a treat, so a fussy dog is likely to take them. |
| You want to see the exact dose | Petz Park | Every product prints its active amounts. ZamiPet does not publish the chew's amounts. |
| Your pet is grain-sensitive | Petz Park | Its powders are grain-free. ZamiPet's chews include rice and wholemeal flour. |
| You want convenience and portability | ZamiPet | A treat-style chew needs no mixing and travels well, which suits a busy household. |
| You have a cat | Petz Park | It has a full cat range. ZamiPet is primarily a dog brand. |
| Your pet is unwell or has a diagnosed condition | See your vet | That needs veterinary care, not a change of supplement format. |
What owners say
These figures were read on 6 July 2026 from each brand's own official pages. Petz Park displays large aggregate review numbers across its store and independent platforms, including a store rating in the high 4s across many thousands of reviews and a Trustpilot score of 4.8 from more than 21,000 reviews. ZamiPet is also well reviewed, presenting strong ratings on its product pages and describing a base of thousands of Australian pet parents, with its Allergy and Itch chew, for example, showing a store-wide rating in the mid 4s. Both brands have real, positive customer bases. The honest point is one of format rather than favour: Petz Park's reviews often mention mixing the powder into food and visible results, while ZamiPet's often mention how readily a dog takes the chew.
The evidence
Neither format is inherently more effective and the honest comparison is about the trade-offs each brings. What makes a supplement work is the right ingredient at an effective dose that the pet actually takes, and the two brands optimise different parts of that. Petz Park optimises the dose and the disclosure: a concentrated powder with no binder ingredients means more room for active per serve and printing the amounts lets you check them against the evidence. ZamiPet optimises the taking: a chew is likely to be eaten by a fussy dog. The trade-off is real on both sides. A chew must include grains and flavour to hold together and taste good, which dilutes the active share and adds ingredients a grain-sensitive dog may not want, while a powder relies on the dog accepting it in food. Neither is a treatment and for any diagnosed condition the ingredient, the dose and veterinary advice matter more than the format.
Not suited for
Petz Park is not the right fit for every pet. If your dog reliably refuses powders on food, Petz Park's format is the wrong tool and a chew like ZamiPet's will serve you better. If your dog needs a grain-inclusive treat-style format for any reason, that is ZamiPet's territory. On the other side, ZamiPet is a dog brand, so a cat owner is better served by Petz Park's cat range. An owner who wants to see the exact dose will also find the chew's undisclosed amounts a drawback. Neither brand is a treatment: a pet with a diagnosed condition, or one that is unwell, needs a vet rather than a switch of format. Petz Park states that safe use in pregnant animals or animals intended for breeding has not been proven across its range.
Final verdict
Choose on your pet and the format that fits. Petz Park is the stronger pick if you want disclosed doses, a more concentrated grain-free formula, weight-calibrated dosing and coverage for cats as well as dogs, all sold direct in AUD from around $32.95. ZamiPet is the stronger pick if your main hurdle is palatability, if you want the convenience of a treat-style chew with no food bowl, or if a portable format matters. Petz Park's powders are flavoured and mix through food, and its review base shows they are widely accepted, so the chew is the answer for the genuinely fussy dog rather than the default. Both are Australian made and vet formulated, so this is a genuine format choice rather than a case of one brand working and the other not. Match it to your pet: a powder for disclosure, concentration and a grain-free formula, a chew for a dog that takes its supplement best as a treat.

How we compared
Every figure on this page was read live on 6 July 2026. Petz Park's format, disclosed ingredient amounts, grain-free formulas, prices, Australian manufacture and review figures come from petzpark.com.au and knowledge.petzpark.com.au. ZamiPet's chew format, its ingredient lists, the grain binders, the 40-day taste guarantee and review figures come from zamipet.com.au, the brand's own site, not a reseller. Where ZamiPet does not publish the amount of an active in its chews, this page says so plainly rather than estimating one. This is a brand-level, format-focused comparison, so it weighs powders against chews overall rather than a single product against another, and the product-level detail is covered on the dedicated Petz Park versus ZamiPet comparison pages. Prices move, so treat any figure as a guide from around the date above.
