Which kibble is best for a senior dog?

A senior dog, generally from around 7 years old for large breeds and more like 8-10 years for small breeds, often benefits from kibble that is slightly less energy-rich, easier to digest and designed to support everyday joint comfort. The right time to switch mainly depends on your dog's size and lifestyle, not only their age in years.

1. From when do we talk about a senior dog?

Entering "seniority" is not the same depending on the dog's size: a large dog ages faster than a small dog, and can be considered senior from 6 to 7 years old, while a small dog can stay close to adult form until 9 or 10 years old. Rather than relying only on a number, it helps to watch for gradual changes: a little less enthusiasm for long walks, a slower start in the morning, or gaining weight more easily than before on the same ration.

2. What changes in dietary needs

With age, a dog's metabolism generally slows down, meaning they need a little less energy to maintain their ideal weight at the same activity level. At the same time, some senior dogs have more sensitive digestion and benefit from kibble that is easier to digest, with well-balanced fibre. Many senior formulas also include nutrients designed to support everyday joint comfort, as part of general wellbeing rather than treating a specific health issue.

3. General guidelines, for information only

Dog size	Indicative age for starting seniority
Small breed (under 10 kg)	around 9-10 years
Medium breed (10-25 kg)	around 8 years
Large breed (over 25 kg)	around 6-7 years

These guidelines are general: some dogs stay very active well past the indicated age, while others show signs of slowing down earlier. Everyday behaviour, and your veterinarian's advice at annual check-ups, should guide the timing of the change, not only the table above.

4. How to choose a senior kibble

• Check for the "senior", "mature" or "7+" / "8+" label on the packaging, which indicates a formula designed for this life stage.
• For a dog who is slightly overweight, a "senior & light" or "senior & weight management" formula may be worth considering.
• Kibble size should stay suited to the dog's build, as with other life stages.
• As with any change, plan a gradual transition over 7 to 10 days to go easy on digestion.

A few formulas to consider:

• BRAVERY Senior Medium & Large with herring, grain-free.
• AMITY Premium Senior & Light, for senior or overweight dogs.
• The full senior dog kibble range to compare available formulas.

5. Habits to adapt alongside diet

Diet is only part of supporting a senior dog. Shorter but more frequent walks, a comfortable, well-padded bed, and regular weight monitoring also contribute to their everyday comfort. Splitting the ration into two meals rather than one can also help digestion in some older dogs.

Weighing your dog regularly, for example once a month, helps spot a gradual change well before it becomes visible to the eye. You can also run your hand along their ribs and spine: you should feel the ribs without excessive pressure, but without them being too prominent either. This simple gesture, repeated regularly, helps adjust the ration before a weight difference settles in for good.

6. Everyday comfort: bowl and environment

Some senior dogs appreciate a slightly raised bowl, more comfortable for dogs whose neck or shoulder mobility has changed with age. A calm environment at mealtimes, away from household bustle, can also help a senior dog eat their full ration quietly rather than leaving it half-finished in the bowl.

7. Signs that should prompt a vet visit

Weight loss, difficulty moving, unusual thirst, behaviour changes or any other notable change should not simply be attributed to ageing: these are signs to have examined by a veterinarian, the only professional able to assess whether these changes are part of normal ageing or need specific follow-up. This article focuses on general dietary advice and is in no way a substitute for veterinary advice.

8. In short

The switch to senior kibble is mainly decided by watching your dog's behaviour and build, with your veterinarian's help, rather than relying only on their age in years. A suitable senior formula, introduced gradually, supports this life-stage change smoothly. For general quantity needs, our article how much kibble for a dog remains a good complementary reference. In all cases, small gradual adjustments work better than sudden changes, both for your dog's digestive comfort and for your own peace of mind.
