Best budget dog food for senior crossbreed

Choosing the right dog food is genuinely complicated — the best option depends on your dog's age, size, breed, and health, and the most expensive or most heavily marketed foods are not always the best fit. That said, if you're already seeing signs of poor digestion, that's worth taking seriously, because the wrong food doesn't just cause discomfort — over time it affects how well your dog absorbs nutrients. To point you somewhere useful: what breed and age is your dog, are there any health issues or sensitivities you're aware of, and what are you currently feeding them?

That makes a lot of sense. Many of the cheapest supermarket dry foods use a high proportion of cereals and low-quality fillers as the main bulk, and some dogs — especially older ones — just don't digest those well. At 8, she's also at the age where a senior-specific formula starts to make a difference: slightly lower protein from better sources, adjusted fat levels, and often added joint support. The good news is you don't need to spend a lot to do better than what she's on. Can you tell me roughly how much she weighs? That'll help me give you an accurate idea of how far a bag will actually go on a daily basis.

Perfect — that's really helpful. For an 18kg senior dog with a sensitive digestion, my clear recommendation is Harringtons Senior Dry Dog Food, either the chicken and rice or the turkey and vegetable variety. It's a complete food made with a named meat as the first ingredient, free from artificial colours, flavours, and preservatives, and the recipe is noticeably gentler on digestion than the cereal-heavy budget brands. It's widely available on Amazon and in most supermarkets, and a 10–14kg bag works out to well under 50p per day for a dog her size — often cheaper per kilo than what you're currently buying. For 18kg fed to senior guidelines, a 10kg bag lasts around 5–6 weeks. The rice-based formula in particular tends to settle loose stools quite quickly, usually within a couple of weeks of switching. Transition her slowly over about a week — mix increasing amounts of the new food with the old — to avoid any temporary upset from the changeover itself.

You'll find it in most large supermarkets — Tesco, Asda, and Sainsbury's usually stock it — as well as Pets at Home and online via Amazon, where the larger bags tend to be best value. If you set up a subscribe and save on Amazon you can knock another 10–15% off the price, which on a regular staple like this adds up. The 14kg bag is the best cost-per-kilo option if storage isn't an issue. At her age and weight, that should keep her going comfortably for around two months.

It's one of the reasons I recommend it for exactly your situation — it's a genuine step up in quality without requiring you to go to a specialist retailer or pay premium prices. If after a month or two the digestion has settled but you want to explore adding a small amount of wet food for variety or palatability, a cheap mixer like a tin of plain sardines in spring water a couple of times a week is a very affordable way to do that. But honestly, for most dogs in her position, switching to Harringtons Senior alone makes a noticeable difference. Good luck with her.
