In short
Both are daily calming products for dogs but are built very differently. Petz Park is a concentrated powder mixed into food. It lists nine calming ingredients and the exact milligrams of each with full transparency. In contrast, ZamiPet is a chicken chew given like a treat. It lists five calming ingredients but does not say how much of each is inside. The price is a small surprise because ZamiPet's pack costs slightly less ($32.95 AUD versus $34.95). What matters more is how long each pack lasts. A Petz Park pack lasts about three times as long, making it far cheaper at around $0.39 per day compared to about $1.10 per day for a small dog.
In summary, if you want visible doses of calming ingredients and the lowest daily cost, choose Petz Park. If your dog needs treats or you prefer shelf convenience, ZamiPet's chew is the better option.

How they differ
Both products go after the same problem in slightly different ways. Petz Park Stress + Anxiety is a supplement first and foremost. The calming ingredients are the whole product and the label gives the amount of each per 2g scoop: Ashwagandha 225mg, St John's Wort 180mg, Vitamin B1 130mg, Magnesium 100mg, L-tryptophan 85mg, Chamomile 60mg, Passion Flower 50mg, Ginger 30mg and L-theanine 20mg.
ZamiPet Relax & Calm is a chew first. According to the ZamiPet website, the main ingredients are Australian chicken meal, rice, glycerol and gelatine. The calming ingredients sit further down the list: L-tryptophan, L-theanine, Valerian, Chamomile and Magnesium. ZamiPet gives no amount for any of them.
Both products name real calming ingredients and the two share three: L-tryptophan, Chamomile and L-theanine appear in each. The practical difference is simple: Petz Park shows you the dose and carries more ingredients, while ZamiPet keeps the amounts to itself and folds them into a tasty chicken chew. Both are made in Australia and both carry a 40-day money-back guarantee.
Why choose Petz Park
You see the dose, not just the ingredient
All nine calming ingredients carry a milligram amount on the label, led by Ashwagandha at 225mg. ZamiPet names five but publishes no amounts.
More calming ingredients
In addition to the L-tryptophan, Chamomile and L-theanine that both products share, Petz Park adds Ashwagandha, St John's Wort, Magnesium, Passion Flower and Ginger.
Far cheaper to run
ZamiPet's pack is a couple of dollars cheaper, but a Petz Park pack lasts about three times as long for a small dog, so it works out to about $0.39 a day compared to about $1.10.
Grain-free and lactose-free
Petz Park is both. ZamiPet is built on chicken and rice, so it is not grain-free.
When Petz Park is the better choice
You are buying for the long haul
Daily calming support adds up. For a small dog, Petz Park is roughly a third of ZamiPet's daily cost, so the savings compound over a year.
You want to know what your dog is actually getting
If a rough estimate is not good enough for you, Petz Park lists the dose of each calming ingredient in milligrams. ZamiPet prints none.
Your dog needs grain-free
ZamiPet is built on chicken and rice. Petz Park is grain-free and lactose-free.
You want the calming ingredients to be the point
In Petz Park's powder, the calming ingredients are the product. In a ZamiPet chew, they sit below chicken, rice and gelatine, so there are fewer of them by design.
When ZamiPet is the better choice
ZamiPet is the better pick in a few real cases. If your dog turns its nose up at powder mixed through dinner, ZamiPet is a chicken chew you give like a treat and plenty of dogs take that more happily. If you would rather buy in person, ZamiPet is on shelves at big chains like Petbarn and Petstock, while Petz Park is mostly bought online. Some owners also look specifically for valerian, a calming herb. ZamiPet includes it and Petz Park does not. One thing is not a deciding factor either way. The 40-day money-back window is the same on both. None of this is a knock on either product. For a dog who only takes treats, the chew format alone can settle the choice.

Cost comparison
Prices are in Australian dollars and were checked on 18 June 2026. ZamiPet's entry pack is a little cheaper, but Petz Park's concentrated 2g scoop makes a pack last much longer, so the daily cost is what separates them. Both brands publish enough to work this out, so it is a fair comparison. Both also sell larger packs that bring the daily cost down further.
| Pack | Stress and Anxiety for Dogs | ZamiPet |
|---|---|---|
| Entry pack price | $34.95, 45 scoops | $32.95, 30 chews |
| Cost per day, small dog (about 10kg) | About $0.39, half a scoop a day | About $1.10, one chew a day |
| Cost per day, medium dog (about 20kg) | About $0.78, one scoop a day | About $2.20, two chews a day |
| Cost per day, large dog (about 40kg) | About $2.33, three scoops a day | About $3.30, three chews a day |
For a 10kg dog, a $34.95 Petz Park pack lasts about three months, so it works out to about $12 a month. A $32.95 ZamiPet pack lasts about a month for the same dog, so it works out to about $33 a month.
Over a year, for a small dog, Petz Park is roughly a third of ZamiPet's running costs for the entry packs. Petz Park stays cheaper per day at every size, though the gap narrows for big dogs.
Both cost more for bigger dogs, since they take more each day. The cost-per-day figures above use each brand's own feeding guide for a small, medium and large dog.
Which should you choose
| Situation | Better choice | Why |
|---|---|---|
| You want the lowest daily cost | Petz Park Stress + Anxiety | Roughly a third of ZamiPet's daily cost for a small dog on the entry packs. |
| You want to see the dose of every ingredient | Petz Park Stress + Anxiety | Nine calming ingredients, each with a milligram amount. ZamiPet publishes none. |
| Your dog only takes treats, not powder | ZamiPet Relax & Calm | It is a chicken chew given like a treat, which fussy dogs often take more readily. |
| You want to buy it in a shop today | ZamiPet Relax & Calm | It is stocked in the big chains like Petbarn and Petstock. Petz Park is mostly bought online. |
| You need grain-free or lactose-free | Petz Park Stress + Anxiety | Petz Park is both. ZamiPet contains rice. |
| You specifically want valerian | ZamiPet Relax & Calm | ZamiPet includes valerian, a calming herb that Petz Park does not use. |
What owners say
Petz Park Stress + Anxiety shows 4.7 out of 5 from 572 reviews on its product page and 465 of those are five-star reviews. Owners most often mention calmer behaviour around storms, separation and travel. They also note that dogs happily accept the roast beef powder once it is mixed into food. ZamiPet does not display a star rating on its product page so we have not assigned a number here. As with any supplement, results vary from dog to dog.
The evidence
A quick note on the ingredients. Both are food supplements, not medicines and neither is a treatment for a diagnosed anxiety disorder. They share several calming ingredients: L-tryptophan, Chamomile and L-theanine are in both. Petz Park adds more, including Ashwagandha, St John's Wort, Magnesium, Passion flower and Ginger. It prints the milligrams of each so you can see the formula rather than take it on trust. ZamiPet uses valerian, which Petz Park does not, but it publishes no doses at all. On a label, ingredients are listed by size. On ZamiPet's list, the calming ingredients sit below chicken, rice and gelatine, suggesting they make up a relatively small part of the chew. We are not claiming either product will calm any particular dog; we are simply comparing what each one contains, how much it contains and how clearly it is shown.
Not suited for
Petz Park Stress + Anxiety is not right for every situation. It is a daily supplement, not a fast-acting sedative and not a fix for a serious, diagnosed anxiety disorder. If your dog's anxiety is severe, please see your vet rather than rely on a supplement. It is also a powder you mix into food, so a fussy dog who will only accept a treat might do better with a chew. Like any calming supplement, it works best alongside training and a settled routine, not instead of them.
Final verdict
Both products give daily calming support for dogs, but they go about it differently. Petz Park is a concentrated powder that lists nine calming ingredients with the milligram of each. It also works out cheaper to run, around $0.39 a day against about $1.10 for a small dog. ZamiPet is a chicken chew you give like a treat. You can also buy it off the shelf in the big chains. If you want a transparent formula at the lowest daily cost, Petz Park is the stronger pick. If you want the convenience of a chew or you would rather buy in store, ZamiPet earns its place.

How we compared
This comparison was compiled on 18 June 2026 from the product pages of each brand: Petz Park at petzpark.com.au and ZamiPet at zamipet.com.au. Prices, ingredients, doses, feeding guides and guarantees are taken from those pages. The cost per day figures use each brand's entry pack price and its own feeding guide, calculated for a small, medium and large dog. Where a figure was not published, we have said so rather than estimate it. ZamiPet does not publish the amount of its calming ingredients, so we have only listed them. It also shows no star rating on its own product page, so we have not stated one.
