This is a specific conversation about Senior dog food — what changes as they age — ask about yours and get one honest answer for your exact situation.

Your vet has flagged something real — senior dogs do have genuinely different nutritional needs compared to adults. Typically that means fewer calories, better digestibility, and more support for joints and organ function. For small breeds like Norfolk Terriers, the timing and format of that switch matters too, since they age a little differently to larger dogs. To point you toward the right food, it'd help to know: how old is your dog exactly, any health conditions flagged at that exam (kidney, weight, joints, teeth), and what are they currently eating?
She's 11, a Norfolk Terrier. The vet just said she's doing well overall but at her age it's worth moving to a senior formula. No specific conditions flagged. She's currently on James Wellbeloved Adult Turkey dry kibble, small breed size.

Good news — if she's in good health at 11 with no specific conditions, you've got a straightforward switch ahead rather than a therapeutic diet situation. Norfolk Terriers are a robust little breed and 11 is solidly senior but not geriatric. A couple of things would help me nail the recommendation: is she currently a healthy weight, and does she have any signs of stiff joints or slower movement — particularly first thing in the morning?
She's a good weight, the vet was happy with that. She has slowed down a bit on walks but nothing dramatic. No obvious limping or stiffness.

Perfect — that tells me a lot. She doesn't need a weight-management or joint-therapeutic formula, just a well-balanced senior food designed for small breeds that eases up on calories slightly, supports digestive health, and gives her joints a gentle boost as a precaution. My recommendation is Royal Canin Mini Ageing 12+. I know she's 11 not 12, but this formula is designed precisely for small breed dogs in the later senior stage, and it's a better fit than a generic 'senior' food for larger dogs. It's highly digestible, supports kidney function proactively, and has the right omega fatty acid profile for joint and coat health. Because she's already on a quality dry kibble with James Wellbeloved, the transition should be easy — mix the two over about ten days, gradually shifting the ratio toward the Royal Canin. Her digestion should handle it well.
That makes sense. Is Royal Canin actually worth the price jump from James Wellbeloved? She's been fine on JW for years.

It's a fair question and honestly JW is a solid food — you haven't been doing anything wrong. The reason I'd make the switch now is that Royal Canin Mini Ageing 12+ is formulated with the specific physiological changes of ageing small dogs in mind: reduced phosphorus to support kidney health, adapted fibre for digestibility, and EPA/DHA levels that JW Adult doesn't match at this life stage. James Wellbeloved does make a Senior range, but it's not small-breed specific in the same targeted way. At 11, with a long, healthy life ahead of her, that extra nutritional precision is where the price difference earns its keep. You're not fixing a problem — you're staying ahead of ones that can quietly develop in this age bracket.
Okay, that's convinced me. I'll look for it on Amazon. Any particular size bag to start with?
inparticular.ai
Start with the 1.5kg bag — Royal Canin Mini Ageing 12+ comes in that size on Amazon UK, which is ideal for a first purchase. It'll last you a few weeks while you complete the transition and confirm she's getting on well with it before committing to a larger bag. Once you know she likes it and her digestion is happy, the 3.5kg is better value for ongoing use. It's usually available on Subscribe & Save too if you want to set and forget the reorders.
