Harley & Marley Senior Dogs & Weight Management review

66.7/100Good
DryAdultSenior

The brand's fish recipe, lightened for a slowing dog, and it lands in our Good band. Fat drops to 9.0% and fibre climbs to 5.5%, so an older dog still gets a proper bowlful. The fish share stays at 61.5%, itemised right down to the digest.

Our view

Likely to suit

  • Older dogs easing off the exercise
  • Dogs carrying a few kilos too many whose owners want them to feel fed after a meal
  • Fish-eating homes with any size of dog, toy to giant
  • Owners avoiding grain. Sweet potato, potato and tapioca do the cereal's job
  • Senior hearts, if taurine matters to you: it is dosed at 500 mg per kilo

Worth watching

  • Fat at 10.1% of dry matter, so a still-busy older dog may need more than you expect
  • Fish oil and fish digest throughout, with no fish-free way to feed it

The score, in context
  1. Harley & Marley Senior Dogs & Weight Management 66.7

All one Good. Typical dry food: Good.

A genuinely fish-led recipe with nothing clever in the small print; the tapioca and pea starch keep the balance reading at Average.

What's in it
  • Fresh haddock, fresh hake15% eachCome in wet; the oven takes that back out.
  • Dehydrated trout, dehydrated fish14% eachCarry most of the finished protein. Trout is named; the other dehydrated fish is not.
  • Fish oil, fish digest2.5%, 1%
  • Sweet potato, potato, tapioca, pea starch, peasThe grain-free base. Tapioca and pea starch weigh on the balance reading.
  • Beet pulp, pea fibrePush the fibre up so a lighter bowl still fills the dog.
  • Sunflower oil, minerals
  • Brewer's yeast, yeast extract, chicory inulinB vitamins and food for the gut bacteria already there.
  • Yucca schidigeraTakes the edge off the smell at the other end.
  • Kale, turmeric, blueberries, broccoli, spinach, rosehip, carrotTrace level, the label's flourish.

Taurine at 500 mg per kilo, with zinc both as the oxide and in a chelated form, plus iron, manganese, copper, iodine and selenium, all dosed in print.

Ash runs high at 13.5% of dry matter, normal for dehydrated fish with bone, and a figure for the vet where a diet is restricted.

Around 270 grams a day for a 15kg adult, a fuller bowl than most kibbles because the food is lighter.

Premium end of the market for a dry food, and the recipe gives good value for that money.
