Also, if you think about it, if the diet is properly formulated for the average adult dog and has the proper protein to calorie ratio, the meat source should not be listed first. (an animal protein source should be in the first 3 ingredients listed).
The diet must add up to 100% right? According to veterinary nutritionists, the average adult neutered dog only needs about 20% protein, 15% fat, and all the proper vitamins and minerals fit inside 5%. So, what's left? The lower calorie carbohydrate should make up the balance of the diet at 60%. Soooooo, if the diet is formulated properly and the manufacturer isn't trying to play marketing games with consumers, the list should accurately reflect the weight of the ingredients and have a GRAIN as the first ingredient.
this is SO wrong. And it's all caused by this stupid use of "%" when talking about dog diets. Dogs need a certain number of grams of protein per day-- they don't need a certain % of the diet to be protein; the protein MUST come from animal sources since veg and grain proteins are incomplete. Dogs need a certain number of calories per day. Dogs don't need ANY carbohydrates per day.
I've posted this before, but I'll do it again. Numbers made up for ease of calculations.
Fido needs 100 grams of meat-protein per day and 1000 calories per day. You feed Fido Brand A which contains 20% protein (let's pretend it's all usable meat-source protein) and has 350 calories per cup. You feed by body weight, so you feed 1000 calories, 2.8 cups. Each cup contains 150 grams of food. So in those 2.8 cups of food there is 420 grams of food, 20% of which is protein, which is 84 grams of protein. Your dog is being starved of protein because of all those calorie-contributing carbohydrates in the food. Over time the lack of protein will seriously adversely affect the health of the dog.
Let's feed Fido Brand B, which contains 30% protein and has 450 calories per cup. You feed by body condition, 1000 calories, which is 2.2 cups. Each cup contains 150 grams of food. So in those 2.2 cups of food there is 330 grams of food, 30% of which is protein, which is only 99 grams of protein! you're still a little short on protein with this so-called high protein food. 1 gram too few per day over the lifetime of the dog can really add up to a significant adverse health impact.
Bottom line unless your dog needs a LOT of calories per day you're not going to get enough protein into that dog unless you choose a food with a very high "% protein" from meat on the label.
