Mighty Munch vs Hero Dog Supplements: A Straight Comparison
Mighty Munch and Hero both make Australian dog supplements for gut health and joint support — but they work differently. Mighty Munch uses powders you mix into food; Hero uses soft chews dogs eat as treats. The right choice depends on your dog's eating habits, your routine, and what you need covered long-term.
- Independently vet-reviewed actives
- Australian-made
- Lifetime guarantee
Hero uses soft chews your dog eats as treats (no food required); Mighty Munch uses powder meal toppers you mix into food. Both cover gut health and joints — only Hero has a calming supplement, a lifetime guarantee, and an antibiotic-safe yeast probiotic.
Mighty Munch and Hero both make Australian dog supplements targeting gut health and joint support. The key difference is format: Mighty Munch mixes powder into food before each meal; Hero's soft chews are eaten as treats with no food needed. Hero also covers calming (Mighty Munch does not), offers a lifetime money-back guarantee vs Mighty Munch's 90 days, and uses a yeast-based probiotic (S. boulardii) that survives antibiotic courses — bacterial probiotics do not.
Best for: allergy-prone dogs, picky eaters, and dogs needing calming support
Hero's meat-free, grain-free chews work without food — ideal for dogs with allergies, fussy eaters, or inconsistent meal habits. It's the only brand here with a calming supplement. The lifetime money-back guarantee removes all purchase risk. If your dog is regularly on antibiotics, Hero's yeast probiotic (S. boulardii) is the antibiotic-safe choice; bacterial probiotics are not.
Best for: consistent eaters, traditional vet joint support, and strong social proof
Mighty Munch has 3,400+ verified reviews on their Probiotics product and uses the traditional glucosamine/chondroitin joint formula most vets recommend. If your dog consistently finishes meals and you want a well-established brand with extensive reviews, Mighty Munch is credible. Note: no calming supplement, and guarantee is 90 days only.

Good
The product is great but it takes too long to get it, I always run out of it by a couple of weeks before my next one gets here. I have 2 dogs, and I have bought the subscription, where it automatically sends the next one. I get notified when it’s been re ordered but then it takes over 2 weeks to get it to me. I find this annoying as it’s an Australia company and I live in Queensland.
— Amber Taylor
Different shape and texture to what we have received on previous orders, one dog will eat them, the other wants nothing to do with them but we will persist. Think I'll chop them up and hide them in her food.

Questions people actually ask
Hero and Mighty Munch both make Australian dog supplements for gut health and joint support, but the formats are different. Hero uses soft chews your dog eats as treats — no food required. Mighty Munch uses powder meal toppers that you mix into your dog's food before each meal. Hero also covers calming (Mighty Munch does not), offers a lifetime money-back guarantee (Mighty Munch: 90 days), and uses a yeast-based probiotic (S. boulardii) that is safe during antibiotic courses.
It depends on your dog. Hero's soft chews are eaten independently as treats — dosing is consistent and simple, no food required. Mighty Munch toppers are mixed into food, which works well for dogs who consistently finish their meals. If your dog is a picky eater or doesn't always finish a full bowl, chews offer more reliable dosing.
Hero's formulas are meat-free and grain-free, making them suitable for dogs with protein or grain sensitivities. Mighty Munch's ingredient lists do not explicitly claim grain-free or meat-free status — verify their current product labels at au.mightymunch.com before choosing if allergies are a concern.
Hero offers a lifetime money-back guarantee with no questions asked and no time limit. Mighty Munch offers a 90-day money-back guarantee with a full refund for any reason. The 90-day window is longer than most brands offer, but Hero's lifetime guarantee has no expiry.
No — as of April 2026, Mighty Munch does not offer a calming supplement. Hero's Calming Daily Chew (Magnesium, L-Tryptophan, Vitamin B1, Jerusalem Artichoke, Ashwagandha, Chamomile) supports anxiety and stress as part of a daily routine. If calming support is a priority, Hero is the only option between these two brands.
