Naturediet - Feel Good Wet Dog Food, Natural and Nutritionally Balanced, Senior-Lite, 390g (Pack of 18) vs Pooch & Mutt - Slim & Slender Complete Dry Dog Food Grain Free (Regular Sized Kibble), for Weight Control and Weight Loss, Chicken and Sweet Potato, 10kg

Q: Which senior dog food brands use named meat sources vs 'derivatives'?

Every product in our top 10 senior dog foods lists named meat sources — chicken, turkey, or both — and zero by-products or derivatives. The highest-scoring product, Naturediet Feel Good Wet (82/100, ingredient quality 83), uses chicken and turkey as its primary proteins. Pooch & Mutt's three entries (scoring 77-78 overall) all use named chicken. Even at position five, Skinner's Field & Trial Light & Senior (74/100) specifies chicken. The gap between best and worst ingredient quality across all 20 products we scored is 18 points (83 for Naturediet down to 65 for IAMS). That spread tracks closely with how specific brands are about their protein sources. 'Meat and animal derivatives' is a legal catch-all that lets manufacturers swap between protein sources batch to batch. Named meats — 'chicken 26%' or 'turkey 30%' — lock the manufacturer into a consistent recipe. For senior dogs with sensitive digestion, that consistency matters. Check the first three ingredients on the label: if you see a specific animal name with a percentage, you know what your dog is eating.

Q: Does senior dog food need to be grain-free?

No. Our highest-scoring senior dog food — Naturediet Feel Good Wet at 82/100 — is not grain-free. It still beats every grain-free option in the category. Among the top five, the results are split: Pooch & Mutt's three products (77-78 overall) are all grain-free, while Naturediet and Skinner's Field & Trial are not. Ingredient quality scores tell the same story. Naturediet leads at 83 despite containing grains. Pooch & Mutt's grain-free formulas score 78-81 on ingredient quality — strong, but not top. Skinner's is gluten-free (not grain-free) and scores 70. What separates good from mediocre senior dog food is named meat content, absence of by-products, and overall formulation quality — not whether grains are present. Grains like brown rice and oats provide fibre and slow-release energy that many senior dogs handle well. The grain-free trend started from concerns about specific grain allergies, which are real but uncommon. Unless your vet has identified a grain sensitivity, choosing based on ingredient quality scores gives you a better predictor of food quality than the grain-free label alone.

What does the data say about Naturediet - Feel Good... vs Pooch & Mutt - Slim & ...?

Naturediet Feel Good Senior-Lite is a wet food, delivered in trays, built around named chicken and turkey as primary proteins. It scores 82/100 at £22.49 for 18 x 390g portions — that works out to around £1.25 per tray. The reduced-fat formula is specifically designed for less active or overweight senior dogs, and it comes without grain-free legume ingredients that have drawn regulatory scrutiny. Pooch & Mutt Slim & Slender is a dry kibble at £47.00 for 10kg, with 45% named chicken and sweet potato, grain-free and well-evidenced for weight loss — it scores 77/100. The DCM concern around pea protein is worth flagging to your vet, particularly for long-term feeding.

If you have a senior dog aged 7-plus who has a delicate stomach or simply prefers wet food, Naturediet is the more straightforward and affordable option. The wet format also helps with hydration in older dogs, which matters more than many owners realise.

If your priority is visible weight loss and your dog refuses most diet foods, Pooch & Mutt has a strong palatability track record across fussy breeds. Just budget accordingly — reviewers consistently flag the price — and check in with your vet if you plan to feed it long-term.
