Pet Food Labels: Good Ingredients - Proteins, Grains, Vegetables, Vitamins
September 25, 2012 by Patrick // Dr. Patrick Mahaney, Food, Treats & Supplements
Do you read the labels on your pet’s food and treats? You should! Understanding what is actually in your pet’s food is important to ensure your pet is receiving proper nutrition.
The FDA regulates all commercially available pet foods and treats. The label appearing on a product is required to list all ingredients and a guaranteed analysis that the product truly contains the ingredients stated – no more, no less.
This series will focus on helping you understand common ingredients in pet foods. There are Good, Bad, and Questionable Ingredients that may appear on any given label. In this article, let’s first look closely at Good Ingredients and tips for identifying them.
Proteins
- Focus on feeding whole food based muscle meat protein instead of fractionated counterparts like “meals” and “by-products”.
- I recommend beef, chicken, fish, lamb, pork, rabbit, turkey, and other animal proteins such as heart and liver.
- Legumes, such as beans (black, kidney, red, white, etc), lentils, and peas also provide quality vegetarian sources of protein, fiber, vitamins, and minerals.
Grains
- Grains provide carbohydrates, protein, fiber, and other nutrients like prebiotics, which are substrates on which pro-biotic bacteria grow.
- I recommend barley, corn, millet, quinoa, rice, and spelt.
Again, it’s important to focus on whole grains instead of their fractionated forms.
Vegetables and Fruit
- Find foods that list whole vegetables instead of hydrolyzed, meal, or starch versions.
- Beet, cauliflower, carrot, eggplant, potato, and spinach provide a healthy source of fiber, phytonutrients, and antioxidants.
- Dried and fresh fruits should also be a part of your pet’s food or added to its diet.
- Choose richly pigmented fresh fruits like blueberry, cantaloupe, cherry, raspberry, strawberry, and watermelon.
- Avoid grapes and raisins – they contain an unknown toxin that affects dogs’ kidneys. Also avoid dried fruits that contain sugar and preservatives like sulfur dioxide.
Fat
- Fat is an important part of any diet because it provides the building blocks of muscle and nerve tissue. Pet foods may contain animal and/or plant based fats.
- Animal fat often comes from the rendering process and is likely to contain toxins (heavy metals, carcinogens, etc). For this reason, I recommend fats from other sources.
- Vegetable fats come from many parts of the plant, including fruit (like avocado, olive, etc), kernel, nut, or seed. Extra virgin, cold pressed olive oil and ground flax seed meal (good ‘meal’) are great vegetarian sources of healthy, polyunsaturated fat and omega fatty acids.
Vitamins and Minerals
- Both vitamins and minerals are added to commercially available pet foods to suffice nutritional requirements per industry standard. These are typically synthetic forms that may not be efficiently absorbed as a result of improper binding with receptors inside the digestive tract.
Vitamins and minerals from whole foods more closely fit the body’s receptors and are better utilized.

Mika,
There is no one way nor one absolute correct method to feeding our pets. As a holistic veterinarian, I highly focus on the quality of nutrients entering my patients' bodies. In order to provide the most pure (free from toxins) ingredients, I suggest feeding a diet based in whole foods instead of processed foods. Processed foods include most common dry and canned dog and cat food and treats.
Dry food has been very high-heat cooked, which denatures proteins and deactivates enzymes. Additionally, dry foods are commonly made at least in part with protein and grain meals and by-products (which do not exist in nature). Canned foods may also have some of these less than ideal ingredients, but they tend to also include more real meat and whole grains along with moisture that benefits the body.
I suggest providing foods that look very similar to the format in which nature creates them and include real meat, vegetables, grains, and fruits. This may be a diet that you purchase commercially or prepare your self. For my clients, I commonly consult with the veterinary nutritionists with the UC Davis Nutrition Support Service in the preparation of home made diets. Otherwise, I suggest dog food from Lucky Dog Cuisine, The Honest Kitchen, Fussie Cat, Weruva, and a few select others.
My preference is for foods that are cooked, as this reduces the concern for bacterial contamination that can cause illness in both household pets and people. Some of my clients feed their dogs and cats raw food, to which I don't necessarily object provided my patients are not suffering from cancer or an underlying immune system disease. When it comes down to concern for biosafety in foods (such as bacterial contamination), all the foods and treats that have been recalled over the past few years have been processed dry and canned foods and not whole food based raw or cooked foods. A great place to visit to keep up to date on food recalls and hot issues in the pet food industry is Susan Thixton's The Truth About Pet Food.
Thank you,
Dr PM
