Senior dog food for Cocker Spaniels

Senior dogs have genuinely different nutritional needs — typically lower calories, better digestibility, and more joint support — but when and how to transition depends heavily on the dog's breed and current health. Cocker Spaniels are a breed I'd keep a close eye on at 12, as they're prone to ear issues, weight gain, and occasionally kidney problems as they get older. To point you toward the best option, can you tell me: does your Spaniel have any diagnosed health conditions, what are they currently eating, and roughly what's your monthly budget for food?

That's really good news that she's holding up well at 12 — that's genuinely old for a Cocker and speaks well of how you've looked after her. Since there are no specific conditions to work around, you have flexibility. The subscription angle makes sense here, and my recommendation is Hill's Science Plan Adult 11+ Small & Mini dry food. It's formulated specifically for small breed dogs over 11, with controlled calories, easy digestibility, and added omega fatty acids for joints and coat — all things a 12-year-old Cocker needs. A 6kg bag runs around £45–£50, but through Amazon's Subscribe & Save you can bring that down to roughly £38–£42 and a bag that size will typically last 5–6 weeks for a Cocker, so you'd land comfortably in your budget.

It's a fair question and worth being honest about. Hill's is a prescription-adjacent brand — vets use their therapeutic lines heavily, which is why the standard range is formulated to a higher standard than most supermarket seniors. The difference with cheaper options is usually in protein quality and digestibility. Older dogs extract nutrients less efficiently, so a food that's slightly cheaper per bag can actually cost more in the long run if she's not absorbing it well, or if it contributes to weight creep. At 12, with no current issues, I wouldn't gamble on a budget brand. Hill's Science Plan 11+ is genuinely the sweet spot between clinical quality and everyday affordability — especially with Subscribe & Save taking the edge off.

At 9kg and relatively active for her age, you're looking at roughly 120–140g per day — Hill's puts feeding guides on the bag and their website, but for a lean senior Cocker that range is a solid starting point. Weigh it rather than scoop it, at least for the first few weeks. Senior dogs gain weight quietly and it sneaks up on you. If she was on a higher-calorie food before, drop down gradually over two weeks to avoid digestive upset — mix 75% old, 25% new for a few days, then 50/50, then flip it.

Good plan. Search for Hill's Science Plan Adult 11+ Small & Mini dry dog food and tick the Subscribe & Save box — you can always pause or cancel if you need to. Given she's doing well at 12, keeping her on a consistent, age-appropriate diet now is one of the best things you can do to keep that going. Hope she enjoys it.
