Feeding your adult dog for everyday health

Once your dog reaches adulthood, typically from around 12 months for most breeds, their nutritional needs shift from the rapid growth stage to steady maintenance. Adult dog food is formulated to support a stable body condition, muscle tone and coat quality rather than the higher energy and calcium levels puppies need to grow. Choosing a formula matched to this life stage helps keep your dog at a healthy weight and energy level day to day. If you're unsure when to move your dog from puppy food to an adult formula, your vet can confirm the right timing based on breed and size.

Matching food to activity level and body condition

Not every adult dog burns energy the same way, so it's worth thinking about how active your dog actually is before choosing a bag or can.

Active and working dogs

Dogs that spend a lot of time running, swimming or working outdoors generally need more energy-dense food to maintain condition. Look for formulas described as suited to active or high-energy dogs, and check body condition over a few weeks to see if the amount is right.

Lower activity and indoor dogs

Dogs that rest more or live mostly indoors often do better on a standard or lighter adult formula, since extra energy intake without the activity to match it can lead to weight gain over time. Weight management ranges exist for this reason, but if your dog has already gained noticeable weight or has an existing health condition, talk to your vet before changing their diet.

Choosing a flavour and format

Adult dog food comes in dry, wet, and fresh or frozen formats, plus grain-free options for owners who prefer to avoid grains in the recipe. Flavour range typically spans chicken, beef, lamb, fish, kangaroo and other proteins, so there's room to rotate or find whatever your dog takes to best. Many owners settle on a dry food as an everyday base and add wet food for variety or extra hydration. If your dog has a sensitive stomach or skin, browsing our fish dog food and other single-protein options can be a useful starting point, alongside a chat with your vet if symptoms persist.

When to consider a different life stage or prescription diet

Adult food is designed for healthy, fully grown dogs without specific medical needs. If your dog is ageing, recovering from illness, or has been diagnosed with a condition such as joint or kidney issues, a senior dog food or a prescription diet recommended by your vet may suit them better than a standard adult formula. Rotating flavours within the adult range is generally fine for healthy dogs, but any bigger dietary change is worth introducing gradually over a week or so to avoid stomach upset.
