Hill's Science Plan Adult 1-6 Light review

38.9/100Average
WetAdult

Hill's Science Plan Adult 1-6 Light is the maker's leaner tin for a dog carrying a little more than it should. Fibre does the work, declared at 2.9% and converting to 12.1% of dry matter, which is a high reading for wet food, and fat is held down to 2.4%. The composition, though, is seven entries long and not one of them names an ingredient, and that is what puts the tin in our Average band.

Our view

Likely to suit

When the vet has raised your dog's waistline, a bulkier and leaner meal makes the conversation easier to act on.

  • Medium adult dogs on a weight plan, which is the job this recipe is written for
  • Dogs that hover hopefully between meals, since fibre at 12.1% of dry matter fills a bowl without much energy behind it
  • Owners who would rather serve one measured tin than weigh out a shrinking portion of the usual food
  • Dogs that need fat kept firmly down, declared here at 2.4% of the tin
  • Households that want a lighter meal without giving up the softness and smell that make a wet food worth eating

Worth watching

There is very little on this label to read, and that in itself is the thing to know.

  • Not one ingredient is identified, so the meat, the cereals and the vegetable derivatives could be any animal and any plant, and could change between batches while the pack stays the same
  • A dog with a diagnosed food allergy cannot use this tin to test anything, because nothing in it is named
  • Various sugars are on the list, which reads oddly in a recipe built around weight control
  • Estimated carbohydrate reaches 44.2% of dry matter, where the typical adult wet food sits at 15.8%
  • Protein converts to 27.5% of dry matter, modest for a dog you want to hold muscle while it loses fat

The score, in context

Lighter recipes are always the hardest thing for a nutrition score to reward. The two levers that lift a reading are meat share and energy density, and a weight control diet sets out to pull both down. Some of the gap here is that.

The rest of it is the composition. Seven entries, every one a legal category, with vegetable protein extracts and various sugars among them, leaves our pillars little to work with. Protein and processing reads Average, with nutritional balance and transparency both Good. That puts the tin in our Average band while the typical adult wet food holds a place well above it in Excellent.

None of this is a verdict on whether the food works. Hill's formulates to a fixed nutrient specification and has decades of clinical feeding behind it, and dogs do lose weight on tins like this one. What our reading can say is only what the label shows, and this label shows almost nothing.

What's in it

Ingredients, as declared: Meat and animal derivatives, cereals, derivatives of vegetable origin, vegetable protein extracts, various sugars, minerals, oils and fats.

Named ingredients

Meat and animal derivatives, cereals, derivatives of vegetable origin, vegetable protein extracts, various sugars, minerals, oils and fats.

Nutritional additives

ADDITIVES PER KG: Nutritional additives: 3b103 (Iron) 8.1mg, 3b202 (Iodine) 0.3mg, 3b405 (Copper) 1.3mg, 3b502 (Manganese) 1.8mg, 3b603 (Zinc) 20.8mg.

Ingredient notes

The list runs meat and animal derivatives, cereals, derivatives of vegetable origin, vegetable protein extracts, various sugars, minerals, oils and fats. Each of those is a legal umbrella, not an ingredient. The first covers any part of any warm blooded land animal, the second any grain, the third almost any plant material, and oils and fats covers fat from any source at all. They are common on big brand wet food and they are not a safety matter, but they do mean the recipe cannot be read, only trusted.

Vegetable protein extracts deserve a moment because they are unusual to see spelled out. Plant protein, separated out from whatever plant it came from, lifts the analysis figure without any meat behind it. Plant protein does not match animal protein for completeness in a dog. The 27.5% of dry matter here is therefore pulling a little less weight than the identical figure would on a meat led recipe.

Fibre is where this tin genuinely differs from an ordinary one. Crude fibre is declared at 2.9%, and once the 76.0% moisture comes out that is 12.1% of dry matter, several times what a standard wet recipe carries. Fibre takes up room in the stomach, slows a meal down and brings very little energy with it, which is the whole mechanism behind a light diet. Expect firmer and more frequent stools while your dog adjusts.

The energy side follows suit. Fat is 2.4% as fed and 10.0% of dry matter, and the tin carries 82 kcal per 100g. Estimated carbohydrate is the largest single component of the dry matter at 44.2%, which is where the cereals and the vegetable derivatives show up. That is a lot of plant for a wet food. It is also the main reason the reading sits where it does.

Calcium converts to 0.83% of dry matter, a comfortable level for adult maintenance. The added trace elements are printed with a figure each, iron at 8.1 mg, iodine at 0.3 mg, copper at 1.3 mg, manganese at 1.8 mg and zinc at 20.8 mg per kilo. That is the one part of the label telling you exactly what you are getting.

One practical note on using it. A weight plan works on measured amounts and regular weigh-ins rather than on the tin doing the job by itself, so agree a target with your vet and feed to that. Getting a dog to accept the smaller ration is the part most owners find hardest, and this recipe makes it easier.

Price and value

Sold in a 370 g pack.

No per-kilo figure had been checked for it when this was written, so no day rate is given here. On portioning, a 15kg adult dog in moderate condition would take about 1023 grams a day at maintenance, working from roughly 840 kcal a day (110 × bodyweight^0.75, the standard maintenance estimate). A dog that is meant to be losing weight should be fed to the target your vet sets rather than to maintenance.
