Opti Life Adult Sterilised/Light: Medium & Maxi review

53.8/100Good
DryAdult

The brand's chicken and rice recipe rebuilt for a dog that gains weight without trying. Fat drops, cellulose goes up and L-carnitine is added, the standard light-diet moves. Dehydrated chicken still leads both labels, so the meat has not been traded away. Both bags sit in our Good band.

Our view

Likely to suit

  • Neutered dogs whose appetite outlived their energy needs
  • Filling the bowl without the calories, as cellulose adds bulk
  • Small dogs on the same plan, with a mini kibble at 11.0% fat
  • Older dogs carrying weight and stiffening with it
  • A named meat share, counted on the label

Worth watching

  • Cellulose is a purified fibre, not the whole-vegetable kind
  • Carbohydrate rises as fat falls, to 51.1% of dry matter on the larger bag
  • Chicken, egg and salmon oil together, and an unnamed fat and protein

The score, in context
  1. Mini 57.5
  2. Medium 53.8

All two Good. Typical dry food: Good.

Both sit level with the shelf; the carbohydrate a light diet brings trims the balance reading, more so on the larger bag.

The stricter cut of the two, for a medium or large dog with real weight to lose.

Both bags lead on dehydrated chicken matched by rice at the same share: 27% on the medium and maxi, 31% on the mini. Cellulose does most of the calorie-diluting, with beet pulp at 1% behind it, and L-carnitine is dosed at 40 mg per kilo on both.

Both carry an animal fat and hydrolysed animal proteins with no species, plus salmon oil and dried whole eggs. Glucosamine is 500 mg/kg on each. What varies is how hard the diet cuts: fat, cellulose and carbohydrate all move between the two bags.
