Leader Adult Slimline Large Breed review
A slimming kibble for a big dog carrying more than it should, and it delivers on that. Fat is pulled down to 7.0% and two starches keep the bowl the size of a proper dinner. Glucosamine and chondroitin are on the list for joints already working hard. It finishes in our Good band.
Our view
Likely to suit
- Large breed dogs that need to shed a few kilos
- A portion that stays generous while the energy drops, at an estimated 318 kcal per 100g
- Heavier dogs with joints under strain
- A big dog slowing down and still eating at the old pace
Worth watching
- Chicken fat on the list despite the turkey on the front
- Protein at 21.1% of dry matter. Keep portions measured and walks going to protect muscle

The score, in context
- Leader Adult Slimline Large Breed 51.3
All one Good. Typical dry food: Good.
Taking fat out means putting starch in, and the score reflects that trade on a food that does what it sets out to.
What's in it
- Dehydrated turkey21%A lean meat, already dried, so the figure survives the oven.
- Brown rice, white rice
- Pea starch, potato starchClose to pure carbohydrate, there to bulk the kibble without fat. This is what separates it from the standard recipe.
- Dehulled oatsThe fibre that helps a hungry dog feel it has eaten.
- Chicken fatSo the bird content is not turkey alone.
- Whole linseedPlant omega 3.
- Minerals, alfalfa, hydrolysed liver protein, yeast extract
- Chicory inulinThe prebiotic.
- Cranberries, beetroot, rosemary, ginger, turmeric, yuccaMore flourish than substance.
- Glucosamine hydrochloride, chondroitin sulphateNo printed amount. Background support for a heavy frame.
L-lysine at 2,860mg per kilo shores up the amino acids, alongside vitamins A, D3 and E and zinc partly as an amino acid chelate.
