Hill's Science Plan Small & Mini Senior Dog Food with Chicken review

53.6/100Good
DryAdultSenior

A small breed senior kibble from Hill's, in our Good band, and a noticeably richer recipe than the brand's slimming bags. Fat runs to 17.6% of dry matter and energy to 379 kcal per 100g, so a small bowl goes a long way. The senior thinking sits in the small print: a named prebiotic blend and fish oil.

Our view

Likely to suit

  • Small and mini breeds in their senior years
  • An older dog with a shrinking appetite, since a modest bowl still does the job
  • Gut support in the food itself, oat bran and fructo-oligosaccharides named at 0.6%
  • Marine omega 3, from fish oil at 1.8%

Worth watching

  • Fish oil plus wheat, barley and oats, so no use to a dog kept off fish or gluten
  • Protein at a modest 22.4% of dry matter for an older dog losing muscle
  • Rich enough that a small dog who never misses a meal needs a measured bowl

The score, in context
  1. Hill's Science Plan Small & Mini Senior Dog Food with Chicken 53.6

All one Good. Typical dry food: Good.

Real senior touches pull the score up, and modest protein on a cereal carrier pulls it back down.

The daily figure for a 15 kg dog is a ceiling; the small dogs this bag is for eat a good deal less.

Premium priced for a dry food, a step more than the analysis earns.
