Royal Canin Maxi Adult In Loaf review
Royal Canin Maxi Adult In Loaf is the large breed wet food in the range, sold as a 410 g pack twelve to a case. It is a soft loaf rather than chunks in sauce, and the analysis under it is rich by wet food standards, with fat converting to 26.0% of dry matter and protein to 41.8%. The list above it is another story. Six entries, four of them legal categories, are what put the loaf in our Average band.
Our view
Likely to suit
Feeding a big dog wet food means big servings, and a larger pack keeps that manageable.
- Large breed adults, which is the size of dog this loaf is written for
- Owners who would rather open one 410 g pack at mealtimes than several small ones
- Dogs that prefer a firm loaf they can take in clean mouthfuls to chunks swimming in sauce
- Dogs that need a richer bowl to keep weight on, with fat converting to 26.0% of dry matter
- Households adding something wet to a dry ration, since the pack's own rows are written as part of a day and not all of it
- Dogs that take in too little water, with moisture declared at 79.2%
Worth watching
For a name this familiar, the pack tells you very little about what is in it.
- Meat and animal derivatives heads the list and stands for any warm blooded land animal in any share, so no exclusion trial can begin here
- Cereals sit second with no name attached, so a different grain can go in each run while the pack reads the same
- Read the printed rows as a top up and not a whole ration, since they are far below a full day of food for the weights beside them
- The energy figure here is ours, not the maker's, so any portion worked out from it needs adjusting to the dog you actually have

The score, in context
The loaf lands in our Average band, with nutritional balance reading Outstanding and protein and processing and transparency both Average. The lower readings come back to one thing: a recipe described in categories, not in ingredients, gives our scoring very little it can verify. That is genuinely the whole of it. Where the figures can be checked they hold up well. Protein converts to 41.8% of dry matter, fat to 26.0% and estimated carbohydrate to 18.8%, only a little over the typical 15.8% for adult wet food. Plenty of foods reach our Excellent band on this shelf less by cooking differently than by naming what they cook with. Royal Canin has been feeding large dogs for decades, and this pack sells on that reputation rather than on its list.

Nutritional additives
ADDITIVES (per kg): Nutritional additives: Vitamin D3: 160 IU, Vitamin C: 30 mg, Iron (3b103): 9 mg, Iodine (3b202): 0.23 mg, Copper (3b405, 3b406): 1.9 mg, Manganese (3b502, 3b503, 3b504): 2.7 mg, Zinc (3b603, 3b605, 3b606): 27 mg - Technological additives: Clinoptilolite of sedimentary origin: 2 g.
Ingredient notes
Four of the six entries are headings, not ingredients. Meat and animal derivatives takes in flesh and processed carcass material from any warm blooded land animal, and cereals takes in any grain. Derivatives of vegetable origin stretches to nearly anything a plant has been worked up into, and oils and fats takes in fat from any animal or plant source at all. None of the four is a hygiene worry, and each is common on big brand wet labels. Together they mean the recipe can be rebuilt behind the scenes without a word on the pack changing.
Yeasts is the one entry that describes itself. Yeast brings B vitamins and the cell wall fibres that are often used as a prebiotic, and it also carries a savoury taste that helps a plain loaf go down. It sits last, so the amount is modest.
Minerals are on the list in their own right, and that is why ash converts to 9.6% of dry matter. Fibre is low at 0.8%, converting to 3.8% of dry matter, so this is a smooth loaf and not a bulky one. The carbohydrate estimate of 18.8% of dry matter says the unnamed cereals are present without running the recipe.
The added panel is the most specific part of the label, and every line carries a figure. Vitamin D3 is at 160 IU per kilo, vitamin C at 30 mg, zinc at 27 mg, iron at 9 mg, manganese at 2.7 mg, copper at 1.9 mg and iodine at 0.23 mg. Clinoptilolite of sedimentary origin follows at 2 g per kilo, a natural clay used to hold the texture of a wet mix together.
Taken as a bowl and not as a list, this is a rich, soft, easy loaf that suits a big dog with a decent appetite. You are trusting the maker on what goes into it, because the pack gives you no other way to know.
Price and value
£6.71 a kilo, in 410 g packs sold twelve to a case.
As a guide, a 15 kg adult dog in moderate condition would eat roughly 933 grams a day, working out at about £6.26. That works from around 840 kcal a day (110 × bodyweight^0.75, the standard maintenance estimate) and from our estimated energy figure. The pack's own rows run from 660 grams a day at 26 kg to 880 grams at 44 kg. That is well under a full day of calories for dogs that size, so they read as guidance for a bowl served alongside something else.
