" Least"

The first three ingredients on the list are ingredients of plant origin (rice, corn flour and corn). It is therefore these components which have been introduced in greater quantities into these foods before cooking. The low phosphorus level of these kibbles reinforces the idea that they seem to be richer in vegetable protein than in animal protein.Vegetable proteins are of less nutritional interest than proteins of animal origin for the dog.

In these kibbles, lipids are mainly provided by animal fats, fish oil, soybean oil and borage oil. The respective omega-6 and in omega-3 are 3.84% and 0.65% including 0.25% of EPA and DHA (long chain omega-3).

" The most"

These kibbles are sources of long-chain omega-3s, but they have an omega-3/omega-6 ratio of 5.9, which is therefore rather unbalanced. Ideally, this ratio should be closer to 4.

Available carbohydrates

In these kibbles, the main sources of assimilable carbohydrates are rice, corn flour and corn. The estimated percentage of assimilable carbohydratesof these kibbles is approximately strong>41%.

Absorbable carbohydrates are carbohydrates that provide energy in the form of calories to the dog. Their percentage is calculated according to the following formula: %assimilable carbohydrates=100-%proteins-%lipids-%cellulose-%ash-%moisture. When not specified by the manufacturer, humidity is estimated at 10%.

" The most"

Rice is the most digestible source of assimilable carbohydrates for dogs. As it is in first position in the list of ingredients, it is the one that is present in the greatest quantity in these croquettes before cooking.

" Least"

These kibbles multiply the sources of assimilable carbohydrates and seem a little too rich in assimilable carbohydrates for the dog.

Calcium and phosphorus

The percentages of calcium and phosphorus in these kibbles are 0.80% and 0.60%, i.e. a calcium/phosphorus ratio of 1.3.

" The most"

These kibbles follow FEDIAF recommendations in terms of calcium and phosphorus content.
