" Least"

Several elements seem to indicate that these croquettes are rather rich in vegetable proteins (of lower quality than animal proteins for the dog) like the low level of phosphorus, the mention of 6 ingredients sources of vegetable proteins on 15 as well as the indication of rice in the first position in the list of ingredients (this means that rice is the ingredient used in the greatest quantity before cooking in these croquettes). The origin of animal proteins and their percentage are not specified.

In these croquettes, lipids are mainly provided by animal fats, soybean oil and fish oil.
The omega 6 content is 3.82% and the in omega 3 is 0.65% including 0.25% EPA and DHA. The omega 6/3 ratio is 5.9.

Available carbohydrates

In these kibbles, the main sources of assimilable carbohydrates are rice, corn and corn flour. The estimated percentage of assimilable carbohydratesof these kibbles is around 40% .

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 the dog and it is the one that is used in the greatest quantity in these kibbles before cooking.

" Least"

These croquettes seem a little too rich in assimilable carbohydrates. This can cause some digestive issues for sensitive dogs who don't digest starch well. The presence of 40% of assimilable carbohydrates and the indication of rice in first position in the list of ingredients support the idea that the proteins in these croquettes are mainly of vegetable origin.

The calcium percentage of these kibbles is 0.82% (i.e. a calcium "concentration" of 2.2 g per 1000Kcal) and their phosphorus percentage is 0.7%, i.e. a calcium ratio /1.2. phosphorus
