Lakes Collection Lakes Heritage Grain Free Light: Trout with Sweet Potato review

61.2/100Good
DryAdult

Lakes Heritage Grain Free Light is one recipe, built on trout and salmon, for adult dogs who need to shed a little without losing interest in dinner. Half the list is fish, with sweet potato and potato behind it for starch and no cereal anywhere. Fat is held down to 8% and energy comes in at 340 kcal per 100g. A joint package is printed with real doses rather than promised on the front of the bag, which is a thoughtful pairing on a food aimed at heavier dogs. Our scoring puts it in the Good band.

Our view

Likely to suit

Getting weight off a dog is mostly about what you put in the bowl, and this recipe is designed for exactly that job.

  • An adult dog with a little to lose, since fat stays at 8% and energy at 340 kcal per 100g
  • A heavier dog whose joints are complaining, since glucosamine and methylsulfonylmethane come in at 170 mg/kg with chondroitin sulphate at 125 mg/kg
  • A dog kept off cereal, with sweet potato at 24% and potato in place of any grain
  • Owners of medium to giant adults who want a diet recipe that still leads with fish rather than filler

Worth watching

There are a few honest details behind the light label that you should have in hand.

  • The whole of the animal content is trout and salmon, one for a fish-avoiding household to note
  • Carbohydrate finishes at 51.6% of dry matter against the 46.2% typical for adult dry food, which is what usually happens when fat comes out of a recipe

The score, in context

Light foods usually pay for their lower fat somewhere, which makes the Good band placement here worth pausing on. The typical adult dry food sits on the very same shelf, and what stands out is that the fish was not cut to make room for the diet. Half the recipe is still declared as named animal, protein holds at 27.2% of dry matter while fat drops to 8.7%, and the joint supplements carry printed figures. Transparency reads Outstanding, with protein and processing and nutritional balance both Average, so the label is the strongest part of the picture. The one genuine counterweight is carbohydrate at 51.6% of dry matter, above the level typical for a dry food, which is the arithmetic consequence of pulling fat down and keeping the bowl filling.

Ingredient notes

The fish half is unusually well itemised: trout freshly prepared at 30%, salmon dried at 11% and freshly prepared at 4%, plus 3% salmon oil and 2% salmon stock. The oven drives off the water in a fresh fish entry, which leaves the 11% dried salmon to supply much of the protein the kibble ends up with. What arrives on the analysis is 27.2% protein on a dry matter basis, which is a genuinely respectable figure for a food this low in fat.

Fat at 8%, converting to 8.7% of dry matter, is the lever this recipe pulls. Energy lands at 340 kcal per 100g against 357 for the typical adult dry food, so a dog eats a similar looking bowl for fewer calories. The salmon oil that remains is there for the omega 3s, with linseed adding the plant form alongside it.

The plant entries begin with sweet potato at 24% and run on to potato and peas at 6%. No wheat, maize, rice or barley appears at any point, so the grain-free claim is sound. Beet pulp does the fibre work, the ingredient most responsible for a bowl that satisfies without adding much.

Pea protein and potato protein deserve a straight word. Neither matches meat for quality or digestibility, and both are by-products of processing. Their presence means the headline protein figure is not all animal in origin. They sit low on the list, after beet pulp, so treat this as a note. As a way of holding protein steady while fat drops, it is defensible recipe design.

The joint supplements are printed as ingredients with figures attached: glucosamine and methylsulfonylmethane at 170 mg/kg each, with chondroitin sulphate at 125 mg/kg. A heavier dog carries more through every joint, so pairing these with a weight recipe is a sensible move. Fructooligosaccharides at 96 mg/kg and mannanoligosaccharides at 24 mg/kg round the label off, both prebiotics aimed at the gut bacteria further down. Asparagus at 0.3% is the garnish that gives the bag its name.

Price and value

Bag sizes are 2kg and 12kg.

A moderate 15kg adult would take roughly 247 grams a day here, on an estimate of about 840 kcal a day (110 × bodyweight^0.75, the usual maintenance calculation). The label asks 135 to 225 grams for a dog of 10kg to 20kg, which is the lower guidance you would expect on a diet recipe, so weigh the portion and adjust by the waistline.
