Notes:

• Some entries above are Australian-owned/manufactured (e.g., Black Hawk, Ivory Coat, Advance, Prime100, Big Dog), while others are international companies with dedicated Australian product lines and distribution (e.g., Purina, Royal Canin, Hill’s, Pedigree). Sources above link to the brands’ Australian product information.
• If you’d like, I can filter this list to: strictly Australian‑owned/manufactured brands only, veterinary-prescription ranges, raw/frozen producers, or by budget/premium tiers — tell me which filter you want and I’ll return a tailored list with stores where each is available.
