Nope, 2 grams of protein to 1 gram of fat. Protein has 4 calories per gram and fat has 9 calories per gram. So if you have 50g of protein, it would be 200 calories, and 25g of fat would be 225calories, so the dog is getting almost the same amount of calories from protein as from fat. 25/50 = 50% fat to protein ratio.

Fat has slightly more than double the calories.
