A 10-year-old Boxer with a greying muzzle — that's a dog who's earned some proper nutritional attention. Boxers age faster than many breeds and are prone to heart issues and certain cancers as they get older, so switching to a food with genuine antioxidant support at this stage is a smart move, not just marketing. To point you to exactly the right thing: is your Boxer currently on any medication or dealing with any diagnosed conditions — heart, joints, digestion, anything like that? And roughly how much does he or she weigh?
She's about 28kg, no diagnosed conditions yet but she's slowing down a bit on walks and the vet just said to keep an eye on her heart at the last check. No meds.

That's useful — a clean bill of health but with the heart flagged for monitoring is pretty typical for a Boxer of her age. At 28kg she's a solid large-breed dog, and the heart mention matters here because some senior foods are higher in sodium than you'd want for a dog in that situation. What are you feeding her currently, and has she had any digestive sensitivity or skin issues over the years?
She's been on a supermarket brand senior food, nothing fancy. No skin issues, digestion has always been fine. I just want something better now she's getting older.

Then she's a good candidate for a straightforward upgrade — no need for anything therapeutic or prescription, just a well-formulated senior kibble with real antioxidant credentials. I'd go with Hill's Science Plan Mature Adult 7+ Large Breed with Chicken. I know the 7+ label looks like it might be too young for a 10-year-old, but that range is actually well-suited to her — it's where the antioxidant blend (vitamins C and E, plus beta-carotene) is specifically designed to support cellular aging, and the controlled phosphorus and sodium levels make it sensible given the heart note from your vet. It's been through proper feeding trials rather than just being formulated on paper, and for a large breed with no current health drama, it hits the right balance without overcomplicating things. Available in a 14kg bag on Amazon UK which works out much better value than smaller bags.
That sounds good. Should I transition her gradually or can I just switch?
inparticular.ai
Always transition gradually, even if her digestion has been solid — it gives the gut microbiome time to adjust to a new protein and carbohydrate profile. A 7–10 day transition works well: start with about 25% new food mixed into 75% old, increase by roughly 25% every two to three days. If you notice loose stools at any point, just slow the transition down rather than abandoning it. At her age, consistency matters more than speed.
Perfect, thank you. I'll order the Hill's large breed senior.

Good choice for her. One small thing worth knowing: Hill's recommends amounts by weight, but Boxers can be prone to weight gain as they slow down, so start at the lower end of the suggested range and adjust based on her body condition over a few weeks — you should be able to feel her ribs easily but not see them. Given the heart monitoring, keeping her lean is one of the most useful things you can do alongside the diet change.
