Digestibility refers to the percentage of protein and nutrients in a dog’s food that are available for use, which can be assessed by the quality and volume of their stool. Small, firm stools indicate better nutrition and less waste. Several factors influence digestibility, including the food formula, nutritional balance, ingredient quality, and processing methods. Variations in these areas can affect how effectively a dog utilizes the nutrients in their diet.

Digestibility is the percentage of a food’s protein and other nutrients available and utilised by your dog. Assuming your dog is in good health, digestibility can be judged by their stool quality and volume.
Small, firm stools are a sign that better nutrition is making a difference inside your dog and less of the food is passing through as waste. Any one of a number of factors influence digestibility:
FORMULA OF THE FOOD BEING FED
The digestibility of the food will vary as the ingredient composition varies.
NUTRITIONAL BALANCE
The correct ratio of nutrients in the diet helps to ensure efficient utilisation of them by your dog.
INGREDIENT QUALITY
Lower quality ingredients can affect the digestibility of a pet food.
PROCESSING
Even a formula of good quality ingredients can have its digestibility reduced by over-cooking or over-processing.
