Senior Dog Food

Why senior dogs need a different approach to food

As dogs age, typically from around seven years old for most breeds and a little earlier for giant breeds, their metabolism, joints and digestion gradually change. Senior dog food is formulated with these shifts in mind, generally offering fewer calories per serve than an adult formula alongside ingredients aimed at supporting joints and easy digestion. The right timing for switching varies by breed and size, so if you're not sure whether your dog counts as a senior yet, your vet can help you judge based on their individual health rather than age alone.

Supporting joints and mobility as your dog slows down

Many senior formulas include ingredients associated with joint comfort, such as added glucosamine or omega fatty acids, alongside a softer kibble texture that's easier to chew. These formulas are designed as general nutritional support rather than a treatment, so if your dog is showing signs of stiffness, limping or reluctance to jump, book a vet check before assuming food alone will fix it. A vet can also advise on suitable exercise alongside any dietary change.

Digestibility and portion size for older dogs

Older dogs often process food less efficiently than they did as adults, which is why senior recipes tend to use more easily digestible proteins and moderate fibre levels. Smaller, more frequent meals can also suit dogs whose appetite has become less predictable with age. Wet food is worth considering if your dog has dental discomfort or simply prefers softer textures, and it can be mixed with dry food to encourage eating without a full switch.

Managing weight in less active seniors

Because most senior dogs move less than they did in earlier years, weight can creep up even on the same portion size as before. Many senior formulas are lower in energy density for this reason, but weight change in an older dog can also signal an underlying health issue, so unexplained weight gain or loss is worth mentioning to your vet rather than adjusting the diet alone.

Choosing a flavour and format your senior dog will actually eat

Appetite can become fussier with age, so having a range of flavours such as chicken, beef, lamb or fish to try is genuinely useful rather than just a nice-to-have. If your dog has developed a sensitivity to a particular protein, single-protein options like our kangaroo dog food range can be worth trialling under your vet's guidance. For dogs eating well on their current adult diet with no signs of slowing down, there's no need to rush the switch: it's about matching the food to how your individual dog is ageing, not a fixed birthday. You can also compare against our adult dog food range if you're weighing up whether it's the right time to change.

FAQs Senior Dog Food

At what age should I switch my dog to senior food?

Most dogs are considered senior from around seven years old, though larger breeds often reach this stage earlier and smaller breeds later. Since ageing varies a lot between individual dogs, your vet is best placed to advise on timing based on your dog's health and breed.

Will senior dog food help with my dog's arthritis?

Senior formulas can support general joint health with ingredients like glucosamine, but they aren't a treatment for arthritis or other diagnosed conditions. If your dog is showing signs of joint pain, see your vet, who can recommend appropriate management alongside any dietary support.

My senior dog has become a fussy eater. What can I try?

Appetite changes are common with age, so trying a different flavour or switching between wet and dry textures can help. Warming wet food slightly or adding a little water to dry kibble sometimes encourages eating, but ongoing appetite loss should be checked by your vet.

Is wet or dry food better for an older dog with dental issues?

Wet food is often easier for dogs with sore teeth or gums to eat, and it can be mixed with dry food to soften it. If you notice your dog struggling to chew or avoiding food altogether, a dental check with your vet is worth booking.

Can senior dog food cause weight loss if my dog eats less?

Senior food itself shouldn't cause weight loss. Unexplained weight loss in an older dog is more often linked to reduced appetite, dental pain or an underlying health condition, so it's worth having your vet investigate rather than assuming the diet is the cause.

How do I transition my senior dog to a new food without upsetting their stomach?

Gradually mix increasing amounts of the new food with the old over seven to ten days, which gives your dog's digestion time to adjust. Older dogs can be more sensitive to sudden changes, so a slower transition than you'd use for a younger dog is generally sensible.
