Fiber is a carbohydrate, but it is not digested and therefore does not impact your dog’s blood sugar level. Ketogenic diets take into account the amount of digestible carbohydrates, also known as net carbs.
To calculate net carbs: grams of total carbs minus grams of fiber equals digestible carbohydrates or net carbs.
