Dry dog food for senior dogs
A senior dog's dry food generally needs to account for a slower metabolism and lower activity level, easier chewing for a mouth that may have lost some teeth, and often some support for joints that have done a lot of work over the years. What it doesn't automatically need is less protein — that's a common myth worth clearing up before choosing a food.
Why fewer calories, not less protein
Older dogs are typically less active than they were, so a food with a slightly lower calorie density helps avoid the gradual weight gain that comes from feeding a younger dog's portion to a body that isn't burning it off the same way anymore.
Protein is a different matter. Older dogs still need good-quality protein to maintain muscle mass, and cutting it back without a specific vet-directed reason can do more harm than good. A food marketed for seniors should be lower in calories and appropriately balanced, not simply lower in protein across the board.
Kibble size and dental comfort
Some senior dogs lose teeth or develop dental sensitivity over time, and a smaller, slightly softer kibble can make mealtimes noticeably more comfortable for a dog who's started to eat more slowly or leave bits behind. This is worth watching for even if your dog hasn't had any diagnosed dental problem yet.
If your dog is struggling to eat dry kibble at all, that's worth a dental check with your vet rather than just switching foods, since it could point to a problem that needs treating rather than working around.
Joint support and what we stock
Many senior dog foods include a joint-support ingredient such as glucosamine as standard, which is a reasonable thing to look for given how common stiffness and joint wear become with age. It sits alongside, rather than instead of, any specific joint care your vet has recommended for an individual dog.
Our senior dog food range and dry food range both include options built around these needs, and our joint care range covers dedicated supplements if your vet suggests additional support beyond diet. As always, how your own dog does on a food — their weight, coat, energy and stools — matters more than any single ingredient on the label.

Common questions
- At what age is a dog considered 'senior'?
- It varies by size and breed rather than a fixed age — larger breeds are generally considered senior earlier than small ones, often from around six to eight years old. Your vet can advise on when it's sensible to consider a senior-formulated diet for your specific dog.
- Should senior dogs eat less protein?
- Not without a specific vet-directed reason. Older dogs still need good-quality protein to maintain muscle mass, and a senior food should generally be lower in calories and appropriately balanced rather than simply cut back on protein across the board.
- My senior dog has started eating more slowly — should I worry?
- It's worth a dental check with your vet, since tooth loss or gum discomfort commonly explain a change like this. A smaller or softer kibble can help in the meantime, but it's better to rule out a treatable dental problem first.
- Do all senior dog foods include joint support?
- Many do, but not all, so it's worth checking the ingredients or asking if you're specifically looking for it. If your vet has recommended a particular level of joint support, a dedicated supplement alongside your dog's usual food may be more reliable than relying on the food alone.
- Can a senior dog go back to an adult formula?
- Some can, particularly if they're still active and at a healthy weight, but it's worth checking with your vet rather than deciding purely on age. What matters more than the label is whether the calorie content and any joint support genuinely suit your individual dog's current needs.
