All dogs need protein in their diet, but the meat- and protein-related claims made on dog food packaging can be confusing. And, in reality, few ingredients used in pet food provide only one type of nutrient. We’ll review what you really need to know about protein and its various sources in dog food.

The Importance of Dietary Protein for Dogs

Let’s start with some dog nutrition basics and why protein is necessary in dog food. Dietary protein is really all about amino acids. Many animal nutritionists will tell you that dogs don’t have a protein requirement; they have a requirement for amino acids in the proper amounts and ratios. Of the 20 or so amino acids, 10 are considered essential for dogs — that means they must be provided in the diet because dogs can’t produce them in their body or can’t make enough of them.

The primary function of protein is to provide essential and nonessential amino acids for muscle development and repair, enzymes, key hormones (like insulin) and antibodies. Proteins are the primary structural parts of muscles, cartilage, tendons, ligaments, skin and hair. Proteins from food are also the body’s primary source of nitrogen, which is critical for making nonessential amino acids, nucleic acids of DNA and RNA, and certain neurotransmitters. Finally, amino acids from protein can be converted into glucose and other energy forms for the body to use to maintain itself and during growth, gestation and lactation. That’s a lot of important functions!

Here’s something to keep in mind: Once a food or ingredient is digested and its nutrients are absorbed through the lining of the small intestine, the original source of the nutrients no longer matters. In the case of amino acids, your dog’s body doesn’t care where the amino acids come from for its use — whether they’re made by the body or supplied in the diet as single amino acids or as intact proteins.

Protein Sources Add Flavor to a Dog’s Diet

Protein sources in dog food also provide flavor. When protein sources are cooked along with fats and carbohydrates, different flavors can be created. Animal nutritionists agree that as the protein content of food increases, the food generally becomes more palatable and acceptable to dogs.

Protein Ingredients That Dog Food Is Made From

Pet food manufacturers can use many different ingredients to supply the protein and amino acids found in dog foods. Essentially, protein ingredients can be grouped into one of three categories:

  • Animal-based ingredients
  • Plant-based ingredients
  • Amino acid supplements

Several protein sources are often combined in pet foods to improve the overall quality and amino acid profile of the finished diet. This practice is known as protein complementation, and it’s used because different protein ingredients contain different amounts of essential and nonessential amino acids. That’s why it’s common to see dog foods with one or more animal proteins, plant proteins and amino acid supplements.

Typical pet food ingredients with high-protein concentrations are meat, meat meal, meat broth, eggs and fish. Taste of the Wild dog food recipes use a variety of different animal proteins, including:

  • Beef
  • Bison
  • Chicken
  • Duck
  • Eggs
  • Fish
  • Lamb
  • Pork
  • Quail
  • Salmon
  • Trout
  • Turkey
  • Venison
  • Water buffalo
  • Wild boar

Animal-based ingredients aren’t the only protein source for pet foods. Plant-based ingredients — such as ancient grains (like quinoa and chia seed) and legumes (like peas, lentils and chickpeas) — are also used for their protein and amino acid content. When added to a dog’s diet, these ingredients not only bring variety, they contribute phytonutrients that are considered beneficial to overall health.

Finally, amino acid fortification is commonly used to improve the protein quality and amino acid profile of dog foods. The three essential amino acids in dietary proteins that are most often in short supply are methionine, lysine and tryptophan. The other amino acid commonly fortified in pet food, especially cat foods, is taurine. Although most dogs can make sufficient amounts of taurine to meet their body’s requirements, some pet food brands, including Taste of the Wild, choose to fortify their recipes with taurine.

How Much Protein Is in Dog Food?

If your dog eats a complete and balanced diet that includes a statement from the Association of American Feed Control Officials (AAFCO) on the label, that food has been formulated to meet the nutritional needs of the pet that the food is intended for. The formula contains all the essential nutrients required (including essential amino acids), and the nutrients are present in the correct ratios for the life stage of that animal (i.e., gestation/lactation, growth, maintenance or all life stages).

How Much Protein Does a Dog Need?

AAFCO sets a minimum crude protein requirement for dog foods of 22.5% on a dry matter basis for growth and reproduction diets and 18% on a dry matter basis for adult dog maintenance diets. How much protein your dog needs depends on their age, activity level, life stage, health conditions, weight management needs and the protein quality of the diet. Excess protein in the diet is broken down and used for energy.

Keep in mind that due to health issues, some dogs may have special dietary needs that require specific protein requirements. For example, lower protein levels are recommended for dogs with chronic kidney disease. On the other hand, high-protein dog food is sometimes recommended for highly active dogs or performance dogs with high energy levels. Always consult with your veterinarian on the appropriate diet needs for your dog and exactly how much protein they should be eating.

What Is the Best Protein for Dogs?

If you have questions about your dog’s food, including the protein sources used in it, talk with your veterinarian. They can assess your dog’s nutritional needs based on age, body condition, activity level and any medical issues. Your vet can also recommend appropriate dog foods, including how much you should be feeding for proper health.

Walking down the pet food aisle or shopping for dog food online can be an overwhelming experience. With thousands of options available, how do you know which food is right for your dog? A good place to start is the dog food label. Learning how to decode it will help you know what to look for when searching for a healthy diet for your dog.

What Information Is on Dog Food Labels?

The information found on dog food packaging is either required or optional, and some sections are more helpful than others when choosing a food. All pet foods must meet the Food and Drug Administration’s (FDA) standards for sale. Under current federal and state regulations, all dog food labels are required to include specific information stated in particular ways:

  • Brand and product name
  • Pet species the product is intended for (e.g., dog)
  • Net weight of the food in the package
  • Guaranteed analysis of specific nutrients
  • Nutritional adequacy statement, which tells the type and the dog’s life stage the product is suited for
  • List of all ingredients in descending order by weight, including water
  • Feeding instructions
  • Calorie content
  • Best by or expiration date
  • Manufacturer’s or distributor’s name and address

While pet food labels are factual, they’re also used to capture your attention in order to provide additional information about product features and benefits.

Pet Food Label Modernization Project

Many pet food regulations are based on guidelines established by the Association of American Feed Control Officials (AAFCO). The Pet Food Label Modernization project was started by AAFCO to align pet food labels more closely with human food labeling and improve consumer understanding. The timing for completion of the project varies by state, but you may notice pet food brands transitioning their labels over the next few years. These changes apply to all pet and specialty pet foods, including complete foods, treats, supplements and mixers.

Changes to the label include: 

  • A “Pet Nutrition Facts” box that looks similar to a human food label
  • Calories stated using common household measurements (e.g., calories per cup)
  • The nutritional adequacy statement relocated to the bottom of Pet Nutrition Facts for easy location
  • The intended use statement required on the lower third of the main display panel to easily identify the intended life stage and purpose of the food
  • Updated ingredient statements to clarify the use of parentheticals and common or usual names
  • Standardized handling and storage directions, and creation of optional icons

How Are Dog Food Ingredients Listed on the Label?

When choosing a dog food, many pet parents begin by checking the ingredient list. Ingredients are listed by weight, which means items with higher water content — such as animal proteins (chicken, lamb, beef or fish), as well as vegetables — often appear before dry ingredients like lamb meal or duck meal, even when the dry ingredients may provide more concentrated nutrition.

Protein sources are especially important because they help support muscle growth, tissue repair and energy needs. Pet food manufacturers can supply the protein and amino acids found in dog foods from three categories: animal-based ingredients, plant-based ingredients and amino acid supplements.

Several protein sources are often combined in pet foods to optimize the amino acid profile and overall nutrient composition of the finished diet. This practice is known as protein complementation, and it’s used because different protein ingredients contain different amounts of essential and nonessential amino acids. That’s why it’s common to see dog foods with one or more animal proteins, plant proteins and amino acid supplements.

Carbohydrates like rice, oats or sweet potatoes provide energy, while fats supply essential fatty acids that support a healthy coat and skin. Vitamins, minerals and antioxidants are also added to promote immune function and overall well-being. Some formulas include ingredients such as glucosamine, probiotics or omega-3 fatty acids (such as fish oil) for joint, heart and gut health.

It’s important to remember that dogs require nutrients — not specific ingredients. Ingredients are simply the sources of those nutrients. In addition to delivering nutrition, ingredients contribute to flavor, texture and freshness, helping create a food dogs enjoy eating while supporting their overall health.

What Is a Complete and Balanced Dog Food?

Although AAFCO does not directly regulate the pet food industry, it sets recognized standards for complete and balanced pet nutrition. “Complete and balanced” means the food provides all essential nutrients for the intended life stage when fed as directed. Dog food can only be labeled as providing complete and balanced nutrition if it meets or exceeds AAFCO’s minimum nutritional requirements or has successfully completed recognized feeding trials.

When selecting a dog food, look for statements indicating that the product is formulated to meet AAFCO nutritional standards or that its claims have been validated through AAFCO feeding trials. The nutritional adequacy statement provides several important details: 

  • Whether the food is complete and balanced, or intended only for supplemental or intermittent feeding 
  • The life stage the food is designed for 
  • How the manufacturer determined the food is complete and balanced

It is also important to choose a pet food produced by a reputable and knowledgeable company that follows rigorous quality control and food safety practices. Taste of the Wild recipes are determined to be complete and balanced by formulation, which is supported with testing of the finished food to verify the presence of key nutrients. Taste of the Wild dog food is made in manufacturing facilities in the United States.

Ingredients to Look for in Dog Food

Some ingredients in pet food provide additional features beyond basic nutrition when used as part of a complete and balanced diet. These “functional” ingredients include whole grains, fruits and vegetables, flaxseed and fish oils for key omega fatty acids, prebiotics and probiotics. 

Every Taste of the Wild dry canine recipe is enhanced with K9 Strain® Probiotics: good bacteria that are added to our recipes to help support healthy digestion. Other functional ingredients included in our recipes include:

  • Blueberries: Rich in fiber and antioxidants, blueberries are considered to be a superfood.
  • Carrots: Rich in vitamin A and like sweet potatoes and pumpkin, carrots get their color from beta-carotene, a powerful antioxidant.
  • Green or yellow peas: Ground to a flour consistency, this carbohydrate source is also a source of protein, fiber and plant-based nutrients such as antioxidants and vitamins.
  • Dried tomato pomace: A fiber source that helps support digestive health and firm stools. Sourced from tomatoes, it contributes vitamin C, lycopene and other important antioxidants.
  • Raspberries: These berries contain antioxidants that help support overall good health.

Ingredients to Avoid in Dog Food

The FDA requires that all ingredients in commercial pet food are safe and have been approved for use. If pet owners are not buying commercially manufactured dog food, they should check that it does not contain ingredients that are toxic to dogs such as garlic, onion, macadamia nuts or chocolate. You should also avoid purchasing dog food with ingredients that you know your dog has sensitivities or allergies to.

Feeding Guidelines for Dog Life Stages

A complete and balanced dog food should provide the essential nutrients dogs need, including protein, fats, carbohydrates, vitamins and minerals. The ideal balance of these nutrients depends on factors such as age, breed size, activity level and overall health. For example, highly active dogs and large-breed dogs often have different nutritional requirements than smaller or less active dogs.

Understanding nutrient requirements is especially important for growing puppies. Puppies require a complete and balanced diet specifically formulated to support healthy growth, strong bones and developing immune systems. 

Adult dogs, on the other hand, benefit from formulas designed to maintain long-term health and energy needs. Senior dogs may require special feeding care because their nutritional needs change with age. As dogs grow older, they often become less active and may gain weight more easily, so they usually need fewer calories than younger adult dogs. Their diet should contain high-quality protein to help maintain muscle mass, along with moderate fat levels and added fiber to support healthy digestion. Many senior dog foods also include nutrients such as glucosamine and omega-3 fatty acids to help support joint health and mobility.

Dogs with certain medical conditions may benefit from therapeutic or veterinarian-recommended diets that help manage symptoms and support overall well-being. Every dog is unique, and feeding habits should reflect individual preferences, lifestyle and health status. The amount, type and frequency of food can vary depending on a dog’s activity level, metabolism and individual needs. 

 

Dog food labels provide an important tool for pet food manufacturers to communicate nutritional information to dog owners. If you are still unsure of what to feed, your veterinarian can help you select the right food for your dog.
