I second that!!! When my dogs were on kibble I wouldn't feed them anything less than 12-15% fat. Anything less and their coats were awful. Now that they are on a raw diet the probably get 70-80% protein and 20-30% fat overall, varies from day to day.
And remember, there are only 3 components of any food source...protein, fat, carbohydrates. So what isn't protein and fat is sugary carbs.
