Here are common dog‑food labels available in Australia that make weight‑management or reduced‑fat/“light” formulas (includes consumer and veterinary diets):

• Royal Canin — Satiety / Satiety Support (vet diet for weight loss/maintenance). (royalcanin.com)
• Hill’s — Prescription Diet Metabolic (and Prescription Diet c/d Multicare + Metabolic). (hillspet.com.au)
• Purina — PRO PLAN weight‑management consumer formulas and PRO PLAN Veterinary Diets OM (Overweight Management). (petspantry.com.au)
• Advance (Australian brand) — Healthy/Weight Control / Healthy Weight range. (innovations.com.au)
• Black Hawk — Healthy Benefits Weight Management formula. (blackhawkpetcare.com.au)
• Ivory Coat — Reduced‑fat / “reduced fat” senior or weight‑management recipes. (all4pets.com.au)

Notes

• Some weight‑management products are veterinary‑exclusive (e.g., many Royal Canin “Satiety” and Hill’s Prescription Diet/Metabolic lines) and should be used under veterinary guidance. (royalcanin.com)
• Other mainstream and Australian brands offer consumer “light/reduced fat/weight control” formulas you can buy at pet retailers. Check the product page or packaging for caloric content, feeding guides and whether the formula targets weight loss (therapeutic) or just helps prevent weight gain (maintenance). (petspantry.com.au)

If you’d like, I can:

• Find the exact product names and pack sizes available near you, or
• Compare calorie / protein / fat numbers for two or three specific formulas you’re considering.
