Harley & Marley Medium/Large Breed review

70.3/100Excellent
DryAdult

Harley & Marley Medium/Large Breed puts 62.5% of the recipe into fish and prints the whole split. That is 15% fresh haddock, 15% fresh trout, 26% dehydrated fish, 5.5% fish oil and 1% fish digest. Sweet potato, potato and tapioca carry the starch, with no grain anywhere on the list. A quiet tail finishes the label: seaweed, chicory inulin and dried vegetables. This one lands in our Excellent band, a step clear of the Good band where the typical adult dry food settles.

Our view

Likely to suit

Feeding a big dog well usually comes down to reading the first line of the label closely, and this one rewards that.

  • Medium and large adult dogs whose owners want fish doing all of the animal work
  • Dogs off chicken, beef and lamb, because this list holds no land animal at all
  • Owners feeding grain free, with sweet potato, potato and tapioca standing in for cereal
  • Dogs whose coats need help from the inside, given fish oil declared at 5.5% and zinc dosed in two forms

Worth watching

Get these details straight before the first bag arrives.

  • The dehydrated fish at 26% names no species, so there is no way here to steer a dog around one particular fish
  • Carbohydrate still converts to 45.0% of dry matter, so the plant side is doing more than the fish headline suggests

The score, in context

Set beside the typical adult dry food, which settles in the Good band, this recipe climbs into our Excellent band. The reasons are unglamorous. Nearly two thirds of the bag is declared as fish with the split printed line by line, protein converts to 28.9% of dry matter, and every added mineral carries a dose. Transparency reads Outstanding and value Excellent. Protein and processing reads Good with nutritional balance Average, the mark of a recipe that spreads its strengths across the whole label.

Ingredient notes

The 62.5% fish headline is broken out in full, and that is the part that earns trust: 15% fresh haddock, 15% fresh trout, 26% dehydrated fish, plus 5.5% fish oil and 1% fish digest. Most of the weight in fresh fish is water, and it goes in the oven. The 26% dehydrated share is what actually fills the finished kibble with protein, and that share is big enough to do the job.

Haddock and trout get named, the dehydrated portion does not. For most dogs that is academic, since it is all fish either way. The question only comes alive if you need one particular fish ruled in or out.

Sweet potato and potato lead the plant side, and tapioca and pea starch sit behind them. There is little in tapioca beyond starch, so read it as part of the kibble's structure. Whole peas do better. They carry fibre and a decent spread of micronutrients. Carbohydrate is estimated at 40.5% as fed, or 45.0% of dry matter, much the same territory as the 46.2% typical for adult dry food, so the fish headline is not buying a low starch bowl.

The omega source is fish oil at 5.5%, which is the form a dog puts to work without having to convert anything first. Chicory inulin follows as a prebiotic, feeding the bacteria already in the gut, brewer's yeast brings a full set of B vitamins, and dehydrated seaweed adds iodine and a broad mineral spread. Beet pulp does the fibre work.

Turmeric, blueberries, broccoli, spinach, rosehip and carrot close the list, all dehydrated and all at trace level. That is the label's flourish and not its substance. This recipe stands up without them.

Every added mineral in the panel carries a printed dose. Taurine is at 500 mg per kilo, and zinc is split across 70 mg of the oxide and 30 mg of a chelated form that a dog absorbs more easily. Then come iron at 75 mg, manganese at 40 mg, copper at 7 mg and iodine at 1.50 mg. Selenium arrives as sodium selenite at 0.20 mg, the form most makers reach for, though selenium bound to yeast is generally absorbed better.

Price and value

£2.33 a kilo, in a 3kg or a 12kg bag.

For a 15kg adult dog in moderate condition, that is roughly 216 grams a day on an assumed requirement of 840 kcal (110 × bodyweight^0.75, the standard maintenance estimate), or about £0.50 a day. The bag's own guide asks 180 to 360 grams for a dog between 10kg and 20kg, so trust the waistline over the table.
