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.

A Kelpie going from farm work to suburban life is a real nutritional gear-change — their calorie needs can drop significantly almost overnight, and if the diet doesn't follow suit, weight gain and joint strain tend to follow fast. Senior dogs also generally benefit from better digestibility and added joint support, though the right timing and approach depends on the individual dog. What's your Kelpie's exact age, any health conditions you're aware of, and what are they currently eating?
He's just turned 10. No diagnosed conditions yet but he's been on a high-protein working dog kibble — Chudleys Working Crunch — since he was about 2. He's moved to a suburban backyard about 3 months ago and I'd say his exercise has dropped from maybe 6-8 hours of active work a day down to two 30-minute walks. He's not overweight yet but I can see it creeping.

That's a dramatic activity drop — going from 6-8 hours of active mustering to an hour of walking is roughly a 70-80% reduction in daily output. Chudleys Working Crunch is designed for exactly the life he used to have, so it's almost certainly delivering far more calories and protein than he needs now. The good news is you've caught it before the weight has actually landed, which makes the transition much easier. Has he had any signs of stiffness after rest, or any changes in digestion since the move?
Yes, actually — he's been a bit stiff getting up in the mornings for the last month or so. And his stools have been a bit looser than usual, which I assumed was stress from the move.

The loose stools could well be stress and environmental adjustment, but a sudden diet mismatch — too much protein and fat for his current activity — can also affect digestion. The morning stiffness is worth paying attention to in a 10-year-old Kelpie; it's common and manageable, but it means joint support should be a priority in whatever you move to. Worth flagging both to your vet at his next check, but in the meantime a diet change is absolutely the right call. I'd recommend switching him to Hill's Science Plan Mature Adult 7+ Large Breed — it's specifically formulated for lower activity senior dogs, with controlled calories, high digestibility, and added glucosamine and chondroitin for joints. It's widely available on Amazon UK. Transition slowly over 10-14 days, mixing it in gradually with the Chudleys to let his gut adjust.
That sounds sensible. Is Large Breed the right fit for a Kelpie though? He's about 20kg.
inparticular.ai
Good question — at 20kg he's right on the border. Hill's defines large breed as 25kg+, so strictly speaking the Medium Mature Adult 7+ would be the size match. However, given his joint stiffness and the fact that Kelpies are a lean, athletic breed prone to joint wear from years of hard work, I'd actually still lean toward the Large Breed version — it carries higher levels of glucosamine and chondroitin, which will serve him better right now. Just portion it according to his target weight of around 20kg rather than the upper end of the range. If his weight stabilises well and stools firm up, you're on the right track.
Perfect, that makes sense. I'll grab a bag and start the transition this week.
inparticular.ai
Good plan. Go slow with the switch — days 1-3 about 25% new food, days 4-6 about 50%, days 7-10 about 75%, then fully over by day 14. Monitor his weight every couple of weeks for the first two months; you may need to adjust portions down slightly as his metabolism settles into the quieter lifestyle. And do mention the morning stiffness to your vet — at 10 it's worth a baseline joint check, and they may want to discuss whether a joint supplement on top of the diet change is worth adding.
