Here are Australian-available dog-food brands that either (a) sell products explicitly labelled “All Life Stages” (single formula for puppies, adults, pregnant/lactating dogs) or (b) offer a full life-stage range (puppy → adult → senior) so you can feed appropriate nutrition throughout a dog’s life.

Notes and tips

• “All life stages” labelling (one bag for puppies → seniors) is different from a brand offering separate puppy / adult / senior formulas. Some vets prefer switching to life‑stage‑specific diets (puppy → adult → senior) because nutrient requirements change with growth and ageing; others accept high‑quality all‑stages formulas for multi-dog households.
• If you want, I can: (a) list single‑product “All Life Stages” items across major retailers, (b) compare guaranteed analyses (protein/fat/Cal) for a few specific products, or (c suggest vet‑recommended options based on puppy/adult/senior needs. Which would you prefer?
