Hill's Science Plan Light Small & Mini Adult Dog Food with Chicken review
Hill's Science Plan Light Small & Mini with Chicken is a weight control kibble for little dogs, and it goes about the job by trading fat for fibre. Chicken and turkey meal leads, with chicken declared at 11% inside 17% total poultry. Cellulose and pea bran meal lift crude fibre to 12.4%, and the energy comes in below what a normal adult kibble carries. It sits in our Good band, the same place the typical adult dry food lands, and for a small dog carrying a bit more than they should it is a practical everyday choice.
Our view
Likely to suit
Your vet has raised the subject of weight, and the bowl is the easiest place to start.
- Small and toy breed adults who need to lose a little, since the food carries 312 kcal per 100 grams against the 357 kcal of a typical adult dry food
- Dogs who beg between meals, because crude fibre at 12.4% fills a bowl without bringing much energy with it
- Owners who want the poultry named, with chicken at 11% inside a total poultry declaration of 17%
- Small dogs with an unsettled gut, since the ActivBiome+ prebiotic blend at 0.6% pairs oat bran with fructo-oligosaccharides
Worth watching
Weight control recipes always involve a trade, and this one is worth understanding before you start.
- Cellulose is doing much of the bulking, and it is a processed plant fibre rather than the sort that arrives inside a vegetable
- Wheat sits second in the ingredients, which rules this recipe out for a dog you are keeping off it

The score, in context
Our Good band holds the middle of the adult dry shelf, and this recipe joins it there by a slightly unusual route. Protein is decent for a light recipe at 25.8% of dry matter, and estimated carbohydrate at 43.8% sits under the 46.2% typical of adult dry food. Energy at 312 kcal per 100 grams is genuinely lower than the 357 kcal norm. What holds it back is the company the meat keeps: wheat second on the list, maize behind it, and cellulose as the fibre of choice. Protein and processing, transparency and value all read Good, with nutritional balance a step back at Average. That is fair on a food that does its stated job competently and nothing remarkable beyond it.

Ingredient notes
Meat comes first here: chicken and turkey meal, with 11% chicken inside a 17% poultry total. Meal is dried, so the water has gone and that percentage still counts once the kibble is made. Protein lands at 25.8% of dry matter, a respectable number for a light food. Holding protein up while dropping fat is the whole aim on a diet, because muscle is the thing you are trying not to lose.
Wheat comes second and maize fourth, with maize protein meal and broken rice around them. Of all the cereals, wheat is the one dogs most often struggle with, and there is a lot of it here. For the many dogs who eat wheat without a second thought, it is simply an effective way to build a biscuit.
The light part of the recipe rests on fibre. Pea bran meal and cellulose lift crude fibre to 12.4% as fed, which is 13.5% of dry matter and far above what an ordinary adult kibble carries. Cellulose is purified plant fibre, near enough indigestible, and its purpose is to occupy space in the bowl and the stomach without bringing energy along. It works, and it is the standard tool for the job. The fibre is manufactured, a long way from what a vegetable brings, and it does nothing beyond bulk.
Behind the fibre sits a genuine digestive addition. ActivBiome+ is declared at 0.6%, oat bran paired with fructo-oligosaccharides. The prebiotic half of that feeds the bacteria living in the large intestine. Dried beet pulp adds fermentable fibre alongside it. On a food that is deliberately bulky, having some of that bulk be fermentable rather than inert is a sensible piece of design.
The minerals are dosed in print, at 132 mg of zinc, 75.6 mg of iron, 7.8 mg of manganese, 7.5 mg of copper, 1.9 mg of iodine and 0.2 mg of selenium per kilo. Calcium works out at 0.89% of dry matter, comfortable for an adult. Animal fat, digest and vegetable oil are all left unnamed, the usual shortcoming of a label built this way. Right at the end sit small antioxidant touches: spinach powder, citrus pulp and tomato pomace.
Price and value
£4.83 a kilo, sold in a 1.5kg bag.
Because the kibble is lighter in energy, a 15kg adult in moderate condition needs about 269 grams a day to reach the 840 kcal maintenance estimate (110 × bodyweight^0.75), which comes to £1.30 a day. Small dogs eat well under that. On a weight plan the amount should keep coming down as the waistline does.
