Senior Border Terrier gaining weight? Best food pick

A 9-year-old Border Terrier who's become quite sedentary and is creeping up in weight — that's a really common pattern, and it's worth addressing now before the extra kilos start putting strain on joints and organs. Senior dogs genuinely do need different nutrition: fewer calories, better digestibility, and more joint support, but the exact approach depends on your dog's breed, health, and what they're currently eating. So — any health conditions I should know about, and what are you feeding at the moment?

Good news that Monty has a clean bill of health — that gives you a real window to get ahead of this before weight becomes a bigger issue. James Wellbeloved Adult Turkey is a decent food, but it's not calorie-controlled for a dog in Monty's situation. At 9, with one short walk a day and mostly sleeping, he's burning very little, and adult maintenance formulas just aren't calibrated for that. One useful question: has he always been on the same portion size, or has it drifted up over time?

That's incredibly common and very fixable. Free-pouring is almost always the culprit — even small daily surpluses compound quickly. Here's what I'd suggest: switch Monty to Burns Weight Control+ Adult and Senior Dry Dog Food. It's a genuinely light, highly digestible formula — lower in fat and calories than standard adult foods, but still complete and nutritionally balanced. Burns is well-regarded for sensitive stomachs and clean ingredients, and this specific variant is designed for exactly Monty's situation: an older, less active dog who needs to lose a little weight without feeling hungry or shortchanged. Crucially, go by the feeding guide on the pack for his target weight, not his current weight, and actually weigh the portion with kitchen scales. That one change alone makes an enormous difference.

Gradually — always. Even with a dog who has no known sensitivities, a sudden switch can cause an upset stomach. Over about 7 to 10 days, mix increasing amounts of the Burns in with decreasing amounts of the James Wellbeloved. Start at around 25% new food, then 50%, then 75%, then fully over. Monty's been on the same food for years so his gut will appreciate the slow transition. Once he's fully on the Burns, give it 6 to 8 weeks before you judge results — weight loss in dogs should be gradual, around 1 to 2% of body weight per week maximum.

Burns Weight Control+ does contain glucosamine and chondroitin, which is a good start for joint support at his age. If after a few months you want to do more, a separate fish oil supplement — like a dedicated dog omega-3 oil — can be worth adding. But honestly, getting his weight down will do more for his joints than any supplement. Extra body weight is one of the biggest drivers of joint wear in older dogs, so you're already tackling the most important thing.
