Hill's Science Plan Adult 1-6 Medium: With Chicken review

41.5/100Average
DryAdult

Hill's everyday kibble for medium adults, built to a fixed nutrient brief, with both recipes in our Average band. That band reads how the recipe is assembled and is no warning about feeding it. The small print is where the brand shows its habits: every mineral dosed, the prebiotic blend itemised.

Our view

Likely to suit

  • Medium breed adults through their middle years
  • Dogs that have eaten cereal-based kibble without a murmur
  • A choice of bird or red meat written to the same brief
  • Owners who want a dose printed against every trace mineral
  • Slightly delicate digestion, with the prebiotic blend at 0.6% on both

Worth watching

  • Wheat at or near the top of both lists
  • Modest declared meat: 14% total poultry, or 9% lamb meal
  • Unnamed animal fat and digest, so neither recipe can anchor a strict exclusion trial
  • Estimated carbohydrate at 53.8% and 54.7% of dry matter, against 46.2% for typical adult dry food

The details

Listed for medium breed adults. The label's table lands on 230 grams a day for a 15kg dog; weigh it and let the waistline settle the difference.

The score, in context
  1. With Chicken 41.5
  2. With Lamb 40.5

All two Average. Typical dry food: Good.

The reasons are structural, cereals first and a small animal share, and the scale does not reward the brand's real habit of holding each bag to the same nutrient targets.

What's in it
  • Wheat, maizeLead the list. Wheat binds a kibble well and most dogs digest it with no fuss.
  • Chicken and turkey mealchicken 9%; total poultry 14%Birds named, and a meal's figure is close to what survives into the kibble.
  • Broken rice
  • Animal fat, digestNo species on either. Digest is the palatant brushed over the kibble.
  • Maize protein meal, vegetable oil
  • Minerals
  • Dried beet pulpFibre, with the oat bran.
  • FlaxseedThe plant omega source.
  • Oat bran, fructo-oligosaccharides0.6% blendThe prebiotic blend, broken down into its parts.

Every trace mineral dosed to the milligram, zinc at 140mg and iron at 84.5mg per kilo, down to selenium.

If your dog has always been happy on poultry, this is the one.

Both recipes are cereal led, with wheat and maize in each and broken rice in each. The added fat and the digest name no species on either label. Protein converts to 23.4% of dry matter in both, and the prebiotic blend of oat bran and fructo-oligosaccharides is declared at 0.6% and broken into its parts. What changes is the named meat: poultry in one, lamb in the other.

In the middle of the dry food market, and the analysis gives less than that price suggests.
