Mighty Munch vs Hero Dog Chews: A Straightforward Comparison
Mighty Munch and Hero are two of the most comparable dog supplement brands in Australia. Both make soft chews for gut health and joint support. Hero also offers a Calming formula — Mighty Munch does not currently have a calming supplement. The differences come down to pack size, probiotic strains, allergy suitability, and what you're backed by if it doesn't work. Here's the honest breakdown.
The Quick Verdict
Choose Mighty Munch if:
- You prefer a brand with a large, established customer base and social proof.
- A 90-day money-back window gives you enough confidence to try.
- Their ingredient profile better matches your dog's specific needs.
- You want a multi-strain probiotic approach.
Choose Hero if:
- Your dog has protein or grain allergies (Hero is fully meat-free and grain-free).

The Quick Comparison
Where the Brands Align — and Where They Diverge
Hero and Mighty Munch are genuinely comparable brands. Both make soft chew supplements targeting gut health and joint support. Both are vet-formulated, Australian-made, and positioned as daily supplements rather than treatments. One notable difference in range: Hero offers a Calming formula for anxiety and stress; Mighty Munch does not currently have a calming supplement. For dog owners comparing the two on gut and joint health, the differences are not obvious from the marketing — they come out in the details.
Pack size: 60 vs 30
Hero provides 60 chews per pack. Mighty Munch provides 30 servings per pack for their probiotic line. For a dog on one supplement daily, Hero gives twice the supply at a comparable price point. This is one of the most straightforward practical differences between the two brands.
Allergy suitability
Hero's formulas are fully meat-free and grain-free across all three products. Mighty Munch's joint formula contains Fish Oil, making it unsuitable for dogs with certain animal protein sensitivities. Verify their full ingredient lists before choosing if your dog has known dietary restrictions.
Australian fulfilment
Both brands manufacture in Australia. Mighty Munch also maintains US-based storage for their US-market orders — for Australian buyers ordering from au.mightymunch.com, this distinction is minimal in practice. Hero manufactures and fulfils entirely within Australia.

Probiotic / Gut Health Formula
S. boulardii (10 billion CFU/g), Organic Prebiotic Pea Fibre, Digestive Enzyme Blend (protease, amylase, lipase), Apple Pectin, Bentonite, Agave Inulin
Grain-free. Fully meat-free. Single high-dose strain with digestive enzymes.
L. rhamnosus, L. plantarum, B. lactis, Inulin
Multi-strain approach. 30 servings per pack. Verify current AU formula at au.mightymunch.com.
Both use science-backed probiotic strains. Hero focuses on a single high-dose S. boulardii (10B CFU/g) with a digestive enzyme blend; Mighty Munch uses a multi-strain approach (L. rhamnosus, L. plantarum, B. lactis). Neither approach is objectively superior — they target the gut microbiome differently. S. boulardii has a strong evidence base for digestive resilience; multi-strain formulas aim for broader microbiome diversity.
Joint Health Formula
MSM, Collagen Peptides (hydrolysed), Turmeric (Curcumin), Calcium Fructoborate, Vitamin C (Ascorbic Acid), Flax Seed, Vitamin E, Manganese, Zinc

Glucosamine-chondroitin-MSM approach. Contains Fish Oil — not suitable for dogs with fish protein sensitivities. Verify current AU formula and format at au.mightymunch.com.
Hero uses a collagen peptide + MSM + turmeric approach (structural + anti-inflammatory). Mighty Munch uses the classic glucosamine-chondroitin-MSM complex with Fish Oil. Hero is hypoallergenic; Mighty Munch's joint formula contains animal-derived Fish Oil and is not suitable for dogs with fish or animal protein sensitivities.
Calming / Stress & Anxiety Formula
L-Tryptophan, Ashwagandha, Magnesium, Chamomile Extract, Vitamin B1 (Thiamine), Jerusalem Artichoke (Inulin), Vitamin C (Ascorbic Acid)
Grain-free. Fully meat-free. No drowsiness. 60 chews per pack.

Pack Size — 60 vs 30
This is one of the most practical differences that's easy to miss when comparing the two brands at a glance. Hero provides 60 chews per pack. Mighty Munch's probiotic line provides 30 servings per pack — half the supply.
At $49.95 for Hero vs $54.95 for Mighty Munch (AU pricing verified April 2026), Hero is both cheaper per pack and provides twice as many daily servings before you reorder. For dogs on a consistent daily routine, this directly affects convenience and value.
Practical note: Dosing for Hero is 1–2 chews per day based on body weight. A 60-chew pack gives a 30–60 day supply depending on your dog's size. At 30 servings, Mighty Munch's probiotic pack lasts 15–30 days at the same dosing frequency. At $54.95 AU for 30 servings vs $49.95 for 60 chews, Hero provides roughly 4× the value per dollar.
