Leader Adult Slimline Medium Breed review
Leader's turkey recipe lightened for medium dogs, and it lands in our Good band. The trade is visible in the analysis: fat down to 8.3% of dry matter, starch up to fill the bowl. L-lysine is added to shore up the protein side, which few slimming kibbles bother with.
Our view
Likely to suit
- Medium dogs that need to slim down without a visibly smaller dinner
- A neutered dog whose appetite has outrun its day
- Quieter dogs, at an estimated 321 kcal per 100g
- Older medium dogs, with glucosamine and chondroitin on the list
Worth watching
- Chicken fat behind the turkey, so not for a chicken-reactive dog
- Carbohydrate at an estimated 59.6% of dry matter against 46.2% for typical adult dry food

- Yeast extract, chicory inulinInulin is the prebiotic, feeding the gut's own bacteria.
- Cranberries, beetroot, rosemary, ginger, turmeric, yuccaThe flourish, though rosemary does real work slowing rancidity.

Against the range
One lighter turkey kibble for medium dogs. Dehydrated turkey is declared at 21%, fat at 7.5%, and pea and potato starch fill the bowl so a measured portion still looks like a meal.
