In short
Both are daily powders you sprinkle on a dog's food to support skin and coat, but they are built on different ideas. Petz Park Skin + Coat is an omega-3 formula, led by EPA and DHA with linseed oil, zinc, biotin and vitamins. It lists a milligram dose for every active. Mighty Munch Collagen is a collagen formula, led by marine collagen with glycine and three probiotic strains. It publishes no amounts at all. If you want a fully disclosed omega-3 skin and coat formula at a lower pack price, Petz Park is the stronger pick at $34.95 AUD against $49.95. If you specifically want collagen, whether on its own or paired with probiotics in one topper, Mighty Munch is built that way and Petz Park Skin + Coat does not contain collagen.

How they differ
These two share a format but not an approach and that is the thing to settle before you choose. Both are powders for dogs, dosed by body weight, made in Australia and given daily on food. What differs is how each one supports skin and coat and how much it tells you. Petz Park Skin + Coat is omega-3 led. Per 2g scoop it states DHA 210mg, EPA 38mg and linseed oil 60mg, which the brand totals as 308mg of omega-3, alongside vitamin C 50mg, vitamin E 20mg, zinc 1mg and biotin 20mcg, plus calcium, zeolite and an antioxidant. Every active carries a number. Mighty Munch Collagen is collagen led. It lists marine collagen, inulin, sweet potato powder, glycine, maltodextrin, silica and three probiotic strains, L. rhamnosus, L. paracasei and L. acidophilus. It does not publish how much of anything is inside, including the collagen. So the honest summary is two different strategies for the same goal. Petz Park works through omega-3 fatty acids and skin nutrients and tells you the dose of each. Mighty Munch works through collagen protein and probiotics and keeps its amounts to itself.
Why choose Petz Park
You can see the whole formula
Petz Park lists every active with a milligram dose per 2g scoop: DHA 210mg, EPA 38mg, linseed oil 60mg, vitamin C 50mg, vitamin E 20mg, zinc 1mg and biotin 20mcg, plus a full nutritional analysis. You know exactly what your dog is getting. Mighty Munch publishes no amounts at all.
A direct omega-3 approach to skin and coat
The formula leads with the fatty acids EPA and DHA, which the brand totals as 308mg of omega-3 a scoop. It adds zinc, biotin and vitamins, nutrients commonly included for skin, coat and nails, rather than relying on a single protein.
A lower pack price
The entry pack is $34.95 AUD against $49.95 for a single Mighty Munch pouch. Petz Park also publishes how many weeks each pack lasts by dog weight, so you can work out the real cost. Mighty Munch does not publish a serving count.
Grain-free, made in Australia
Skin + Coat is made in Australia and is grain-free. Mighty Munch does not state whether its collagen topper is grain-free.
A large, current review base
4.8 out of 5 from 560 reviews on the product page, with owners commonly citing less scratching, shinier coats and stronger nails.
When Petz Park is the better choice
You want to see the full formula and the doses
Petz Park publishes a milligram amount for every active. If knowing exactly what is in the product matters to you, this is the clearer choice.
You want an omega-3 led skin and coat formula
The blend leads with EPA and DHA and adds zinc, biotin and vitamins, rather than a single protein.
You want the lower price
A $34.95 AUD entry pack against $49.95, with published pack durations so you can check the real cost for your dog's size.
You want a grain-free powder
Skin + Coat is grain-free and made in Australia. Mighty Munch does not state whether its topper is grain-free.
When Mighty Munch is the better choice
To be fair to Mighty Munch, there are clear cases where it is the better buy and they are worth stating plainly. If you specifically want a collagen supplement for your dog, Mighty Munch is built around marine collagen and Petz Park Skin + Coat contains none at all, so that is a real difference, not a small one. If you want skin and coat support combined with probiotics in a single topper, Mighty Munch includes three probiotic strains, whereas Petz Park keeps probiotics in a separate product. Mighty Munch also offers a 90-day money-back guarantee, compared to Petz Park's 40 days, giving you more time to decide. It is also an established brand that markets itself as vet-approved. If a collagen-led or probiotic-led approach is what you are after, Mighty Munch is the product designed for it.

Cost comparison
Here is what each costs in Australian dollars, current as of 23 June 2026. Petz Park publishes how long each pack lasts for each dog's weight, so the cost per day can be calculated. Mighty Munch does not publish a serving count per pouch, so a like-for-like cost per serve cannot be verified.
| Pack | Skin and Coat for Dogs | Mighty Munch |
|---|---|---|
| Entry pack | $34.95 AUD for 45 scoops | $49.95 AUD for one pouch, serving count not stated |
| Mid pack | $56.95 for 90 scoops | $99.00 for three pouches |
| Largest pack | $99.95 for 180 scoops | $199.95 for nine pouches |
| On subscription | Around $31.46 for 45 scoops, 10% off | Not offered on this page |
For a dog under 11kg on half a scoop a day, a 45-scoop Petz Park pack lasts about thirteen weeks, so the $34.95 AUD pack works out to roughly $12 a month. Mighty Munch's monthly cost cannot be calculated because the servings per pouch are not published.
Petz Park's 180-scoop pack at $99.95 AUD lasts about a year for a dog under 11kg, on the published scoop count and dose. A yearly figure for Mighty Munch cannot be verified without a serving count.
Costs rise with dog size for both, since larger dogs take more a day. Petz Park doses up to three scoops daily for a dog over 36kg and Mighty Munch up to three scoops for a dog over 45kg.
Which should you choose
| Situation | Better choice | Why |
|---|---|---|
| You want a fully disclosed omega-3 skin and coat formula | Petz Park Skin + Coat | EPA and DHA led, with a milligram dose listed for every active and a full nutritional analysis. |
| You specifically want a collagen supplement | Mighty Munch Collagen | It is built around marine collagen. Petz Park Skin + Coat contains none. |
| You want skin and coat support combined with probiotics in one topper | Mighty Munch Collagen | It includes three probiotic strains. Petz Park keeps probiotics to its separate product. |
| You want the lower price per pack | Petz Park Skin + Coat | A $34.95 AUD entry pack against $49.95, with published pack durations. |
| You want the longest money-back window | Mighty Munch Collagen | A 90-day guarantee against Petz Park's 40 days. |
What owners say
Petz Park Skin + Coat is rated 4.8 out of 5 based on 560 reviews on its product page, as of 23 June 2026. Reviewers most often mention less scratching, softer and shinier coats and stronger nails. They also note the powder mixes easily into food. Mighty Munch Collagen has a 4.7/5 rating on its product page. The page displays the number of reviews in multiple ways. The visible reviews also span several years and more than one product, so we have quoted only the 4.7 rating it displays and have not put a single count beside it. Results vary from one dog to the next.
The evidence
It helps to understand what is in each tub and to keep it honest. These are food supplements for dogs, not medicines, and they are not a treatment for a diagnosed skin condition. Petz Park's formula is built on the omega-3 fatty acids EPA and DHA, which are widely used in skin and coat supplements, alongside zinc, biotin and vitamins C and E, nutrients commonly associated with skin and coat condition. Petz Park publishes the amount of each, so you can see the formula rather than take it on trust. Mighty Munch's approach is collagen-based. Collagen is a structural protein and the brand pairs marine collagen with glycine, an amino acid and three probiotic strains, on the idea that skin, coat and gut are linked. Mighty Munch does not publish the amount of collagen or of anything else. We make no claim here that either product will change a given dog's coat. We are comparing what each formula contains and how clearly each one is disclosed.
Not suited for
A few honest words on where Petz Park Skin + Coat might not be the right pick for you. It is a food supplement for dogs, not a medicine, so it is not meant to diagnose, treat or replace veterinary care for a diagnosed skin condition. It contains fish-derived omega-3, so it is not the one if you are avoiding marine ingredients. It does not contain collagen, so if a collagen supplement is what you want, Petz Park is not for you. Allow four to six weeks of daily use before judging results. Follow the dose for your dog's weight as this product has been calculated appropriately for optimal effectiveness. It is for dogs only, made in Australia and grain-free.
Final verdict
For most dogs, Petz Park Skin + Coat is the one we would choose for skin and coat. It leads with omega-3, EPA and DHA, adds zinc, biotin and vitamins for skin and nails, then puts a number on every active so you can see the whole formula. It is grain-free, costs less per pack at $34.95 AUD and publishes how long a pack lasts so you can check the real cost. Mighty Munch Collagen is still a good product. It is the better pick in two clear cases. The first is if you specifically want collagen, which Petz Park Skin + Coat does not contain. The second is if you want collagen and probiotics together in one topper. It also gives you a longer 90-day guarantee. For a fully disclosed omega-3 skin and coat formula at a lower price, Petz Park is the stronger buy.

How we compared
A quick word on how we put this together because being fair to both products matters to us. This is Petz Park's own comparison, so we have worked to give you a straight read on each one. Every figure here comes from each brand's own page, checked on 23 June 2026. We used Petz Park's page at petzpark.com.au and Mighty Munch's collagen page at au.mightymunch.com. Two things are worth being open about. Mighty Munch's page shows its review count in more than one place and the figures do not match, so we have quoted only the 4.7 out of 5 rating it displays and have not stated a single count. Mighty Munch also does not publish the pack weight or the number of servings per pouch, so a like-for-like cost per day cannot be worked out for it without guessing. We do not guess. Petz Park publishes its scoop count, scoop size and dose by weight, so its cost per day is shown in full. Where a brand does not publish something, we say so plainly. All prices are in Australian dollars.
