Fats contain about twice as much energy as proteins and carbohydrates. The metabolisation of 1 gram fat gives approx. 9 kcal, while 1 gram carbohydrates or 1 gram protein only gives 4 kcal.
High fat diets are indicated for dogs which require a lot of energy. Diets for working dogs or sporting dogs (sledge hounds) should contain high fat levels. In the Husse product range, Husse Optimal Energi with 22% fat is the dog food with the highest energy content.
