Dog Food Ingredients and Claims: What Do They Mean?

So, you’re standing in the aisle of the pet food store trying to make sense of the terms on the ingredient panel. If the first ingredient was a protein source (lamb, chicken, venison etc), and if somewhere on the bag appeared the words premium, ultra premium, natural, complete, balanced or 100% nutritious; that might have been enough for you to feel confident about the quality of the food you were holding and lead you to purchase it. But have you ever wondered what some of those terms actually mean? Terms like meat meal, fish meal, chicken by-product meal, poultry by-product meal, chicken fat, poultry fat.

Many pet foods are labeled as “premium,” and some now are “super premium” and even “ultra premium.” Other products are touted as “gourmet” items. Products labeled as premium or gourmet are not required to contain any different or higher quality ingredients, nor are they held up to any higher nutritional standards than are any other complete and balanced products. Source Food and Drug Adminsitration

In other words, foods boasting the the terms premium, super premium, natural, holistic, and whatever other healthy sounding words you find on a dog food bag, really don’t mean anything in terms of more healthy or nutritious for your dog, as compared to any other dog food.

So What Does Complete and Balanced Mean?

There are two ways (either/or) that a pet food company can can call their product “complete and balanced”.

  1. The product must meet nutrient guidelines as established by the AAFCO Dog Food Nutrient Profile .
  2. The second method involves testing/feeding a specific product to dogs in a brief 6 month feeding trial.

I’ll talk more about AAFCO Feeding Trial Protocols in a future post, but for now suffice it to say that the requirements for a product to pass the AAFCO test are pretty loose to say the least.

What are By-Products?

By-products are animal parts left over from the processing of human foods that are deemed unfit for human consumption. These “parts” which can include bones, blood, intestines, lungs, ligaments, heads, feet and feathers, are used for feed for poultry and livestock and also end up in pet foods. It’s interesting that by-products unfit for human consumption are in turn fed to chickens and cattle which we end up eating anyway. :/


What is “Meal”?

Meat meals, poultry meals, by-product meals, and meat-and-bone meal are common ingredients in dry pet foods. The term “meal” means that these materials are not used fresh, but have been rendered. Since rendered tissue is devoid of water, the finished “product” has a  higher protein content by weight, than the tissue it was rendered from.

What is Rendering?

Rendering is the process of cooking (usually at high temperatures) raw animal material to remove the moisture and fat. The high rendering temperatures 270F/130C can destroy beneficial naturally occurring enzymes contained in the raw ingredient.

AAFCO’s Definition of Poultry Fat

“Poultry Fat Poultry Fat (feed grade) – primarily obtained from the tissue of poultry in the commercial process of rendering or extracting.”

Primarily?! What does that mean? Animal Fat is another one that’s kind of ambiguous. I’d be more comfortable with a named fat source like Chicken Fat.

Go here for more reading about what is in pet food.

“Pet owners and veterinary professionals have a right to know what they are feeding their animals. The pet food label contains a wealth of information, if one knows how to read it. Do not be swayed by the many marketing gimmicks or eye-catching claims.” – The Food and Drug Administration

Bottom line, read the labels, do your research and don’t we swayed by marketing and pretty packaging. Or, go raw.


  1. A Bag of That Complete & Balanced Dog Food Please
  2. If I Were to Buy Kibble, What Would I Buy?
  3. Will Work for Table Scraps
  • Your comment: "It’s interesting that by-products unfit for human consumption are in turn fed to chickens and cattle which we end up eating anyway," makes me glad I don't eat meat. I have been giving my cat cooked chicken and turkey and vegetables. One of my friends cooks a big dinner, which she shares with her dogs. That way she knows that she and her dogs are eating well.
  • The more natural the stuff you feed your dog (and yourself), the less a label needs to explain. What happened in our lives that caused the collective "Us" to abdicate responsibility for what we feed our dogs (and ourselves)? Why does everything have to be convenient - pre-mixed, pre-made, pre-everything - so people can go out and do all the things they imagine have some importance in this lifetime ... as opposed to, say, REALLY TAKING CARE OF THE ANIMAL YOU ARGEED TO TAKE RESPONSIBILITY FOR!

    Jim, this is another great post in your dog feeding series. Hopefully, it's a wake up call for other people who get drawn to your site.
  • Thanks Rod, You hit it on the head. Most people wouldn't think about feeding their kids Kraft Dinner every single day of their lives, even though that would be cheap and convenient.

    In my opinion, when somebody decides to take on the responsibility of guardianship for a companion animal, that responsibility encompases all things required to give that animal a safe and healthy life, diet, exercise and medical attention when needed. A dog has a realatively short lifespan - shouldn't it be our responsibility to make its time on this earth count?

    At the very least, with regards to what we feed our pet(s), I think we owe it to them to investigate and educate ourselves as much as we can, about what feeding our pets a truly healthy diet means.

    In the best interest of our pets, we owe it to them to question the status quo of current feeding practices, imo.
  • "gourmet" and "premium" are marketing words that are specifically targeted to evoke emotional responses in the buyer. Words like that subliminally convince people that they are buying the best food for their pets, which is not true.

    And thanks for explaning some of those ingredient terms, I'm going to go barf now...
  • Oh yes, of course you should BARF (Biologically Appropriate Raw Food) =P
  • :-)
  • Yes, you need a strong stomach when looking into this stuff and realizing...just wait til you hear what AAFCO successful testing parameters include! I'll leave that to Jim since he mentioned he was working on it.
  • The other thing that is missing is the amount of an ingredient. They can say chicken is the primary ingredient, but that is by weight before cooking. So all the other ingredients behind it, what % of the food are they? Is that chicken 25% of the food, 50% of the food or 75% of the food?

    Terms that include "formula" mean the named meat source has to be 25% like Chicken and Rice Formula. If it says "with" Chicken and rice, then the named meat source only has to be 3% - that is a HUGE difference! Those figures also come from the FDA.

    I would love to see packaging like this (these are my made up % to use as an example):

    After cooking, this kibble includes:
    50% Meats: Lamb Meal, Lamb, Chicken, Chicken-by-product meal.
    15% Fats: Chicken Fat, Fish Oil
    10% Grains: Rice, oats
    15% Fruits and Vegetables: Peas, Apples, Broccoli, Kale, Cranberries, Blueberries
    10% Minerals and Probiotics: L. Acidophilus, Vitamin b12 supplement, etc....

    Guaranteed Analysis:
    Crude Protein = 34% Min, 38% Max
    Crude Fat = 17% Min, 21% Max
    Carbohydrates NFE = 28% Max
    Omega 6 = x %
    Omega 3 = x %
    Caloric Distribution
    % for Protein, % fat, % Carbohydrates

    At least then if someone is buying a food they know what they are buying vs. a guessing game in the store. Are you buying meat for your dog or meat flavored grains?





















  • How about following guidelines for human nutritional analyses?

    Nutrition Facts

    Per 454g/cup

    Protein (animal source): 45g
    Carbohydrate (sans grains): 10g
    Fat: 20g (marine source)
    Calories: 400

    **these numbers are just for example

    In human sports nutrition, protein from vegetable sources is almost never included in a diet as they are incomplete (meaning they don not contain all 8 essential amino acids) and inferior as compared to animal source protein. For the same reason, protein counts in pet food should not include protein from vegetable sources. Of course they are, for one reason and one reason only, and that is to be able to cheaply "bump up" the amount of protein listed on the label.
  • thats a good idea!
  • Rob - this would be fantastic!! I'm a person of at least average intelligence, and I found reading dog food ingredients to be completely overwhelming. There are so many definitions you need to know - I mean, "meal" doesn't sound that bad until Jim lets us know what it really means! Yuck!! The simple example you gave would be wonderful.
  • Too many definitions that is for sure!
