Pro Plan Medium Puppy OptiStart review

46.3/100Average
DryPuppy

A dense, high-energy growth kibble with its calcium declared, which plenty of puppy labels skip. Energy reaches 405 kcal per 100g and the added panel is printed in full. Cereal and plant protein make up the bulk behind the chicken, and that holds it in our Average band.

Our view

Likely to suit

  • Medium breed pups in their fast-growing months
  • Owners who read the calcium line first: it is declared and converts to 1.63% of dry matter
  • Hungry pups that need the energy, at 405 kcal per 100g against 376 for a typical puppy dry food
  • Trace elements written out, iron at 120 mg/kg and zinc at 110 mg/kg among them
  • Feeding by expected adult size, which is how the pack's guide is laid out

Worth watching

  • Wheat and soya near the top of the list
  • Calcium above the ceiling large breed growth is held to
  • Animal fats and digest both unnamed, so no exclusion diet from this label
  • Fat at 20.7% of dry matter, so weigh portions for a steadier pup

The score, in context
  1. Pro Plan Medium Puppy OptiStart 46.3

All one Average. Typical dry food: Good.

The recipe leans on cereal and plant protein behind a fifth of chicken, and the well-dosed panel cannot lift it past that.

What's in it
  • High quality chicken (back and chest)20%The cuts are named, unusual for a mainstream kibble. It is fresh, so much of it is water lost in the kiln.
  • Dried poultry proteinWhere the lasting protein comes from. Poultry covers any farmed bird.
  • WheatA binder, and often the first suspect when a pup does not agree with its food.
  • Soya mealPlant protein, digested less completely than meat.
  • Animal fatsNo species named.
  • Rice, corn8% riceA broad cereal side.
  • DigestAn animal-derived coating that makes the kibble go down readily. Source unnamed.
  • Dried beet pulp, corn protein meal, minerals
  • Fish oil, dried eggLong-chain omega 3 for brain and retina; egg lifts protein quality.
  • Dried colostrum0.1%The OptiStart element, there for early immune support.

Fully dosed, from 29000 IU/kg of vitamin A down to 0.13 mg/kg of selenium, with tocopherol extracts keeping the fats fresh.

Calcium converts to 1.63% of dry matter, workable for a medium frame and above the ceiling for large breed growth.

The daily amount moves as the pup grows: start where the chart puts them and revise it over the months.

Middle of the market for a dry food, and a little more than the analysis justifies.
