Why You Should Include Fish in Your Dog's Diet

Feeding your dog a nutritious, balanced diet is one of the most important ways to ensure long-term health. While chicken, beef, and turkey are common protein sources in dog food, fish is an often-overlooked superfood for dogs. Fish is packed with high-quality protein, essential fatty acids, and other nutrients that support healthy skin, a shiny coat, brain function, and overall wellness.

At NutriCanine, we carefully select fish from sustainable Canadian fisheries to create fresh-cooked recipes that dogs love and that provide real health benefits. This guide will explain why fish is a top choice for your dog and how our salmon-based recipes are formulated for maximum nutrition.

Overview of Fish in Dog Food

Fish is a highly digestible source of protein that delivers a wide array of essential nutrients in forms that are easy for dogs to absorb. Unlike some proteins from red meat or plant sources, fish contains all of the essential amino acids that dogs need for muscle maintenance, tissue repair, and overall growth, making it a complete and balanced protein source. This is especially important for puppies, senior dogs, and highly active breeds that require high-quality protein to support lean muscle mass and sustain energy levels.

In addition to its protein content, fish is naturally rich in EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid)—long-chain omega-3 fatty acids that are critical for a dog’s health. These nutrients are known to support healthy skin and a shiny coat, reduce inflammation in joints and tissues, and contribute to brain health, including cognitive function and development in puppies. Unlike plant-based omega-3s, which must be converted in the body to EPA and DHA (often inefficiently), fish provides these fatty acids in their active form, ensuring your dog receives maximum benefit.

Fish is also gentle on the digestive system, making it an ideal choice for dogs with food sensitivities, allergies, or digestive issues. Its easily digestible protein is less likely to trigger gastrointestinal upset, compared to heavier meats like beef or pork. Beyond protein and omega-3s, fish delivers functional nutrients such as vitamins (B-complex, vitamin D) and minerals (selenium, iodine) that contribute to overall wellness, including immune support, heart health, and healthy metabolism.

By including fish as a primary protein source in your dog’s diet, you are providing a nutrient-dense, easily digestible ingredient that not only fuels daily energy needs but also promotes long-term health, from skin and coat condition to cognitive function and joint support. This makes fish an exceptional choice for a complete, balanced, and highly functional dog diet.

Types of Fish Used in Pet Food

Not all fish are created equal when it comes to dog nutrition. While fish is generally a highly digestible and nutrient-rich protein source, the specific type of fish can significantly affect the vitamins, minerals, and fatty acids your dog receives. Some fish are naturally higher in omega-3 fatty acids, while others are leaner or richer in certain minerals. Additionally, certain species may carry environmental contaminants like mercury or PCBs if consumed in large quantities, which is why choosing high-quality, sustainably sourced fish is essential for your dog's health.
Common fish used in dog food include:

Salmon: Salmon is widely regarded as one of the best fish for dogs. It provides high-quality, easily digestible protein and is naturally rich in long-chain omega-3 fatty acids (EPA and DHA), which support skin, coat, joint, and brain health. Salmon is also highly palatable, making it an excellent option for picky eaters or dogs with sensitive stomachs.
Whitefish (cod, haddock, pollock): These mild-flavored, lean fish provide readily digestible protein without a strong taste, which can be appealing to dogs who are sensitive to fishy flavors. While lower in omega-3s than salmon, whitefish still provides important protein and essential nutrients, making it a solid choice for balanced diets.
Trout: Often sourced from freshwater environments, trout offers many of the same benefits as salmon, including a good balance of protein and omega-3 fatty acids. It is also gentle on the digestive system and is suitable for dogs with food sensitivities.
Sardines: Small, oily fish like sardines are rich in calcium, phosphorus, and omega-3 fatty acids. They also provide natural antioxidants and are often included in pet foods to boost micronutrient content. Sardines are an excellent addition to diets that need extra DHA/EPA support.
Herring: Herring is a nutrient-dense fish that provides high-quality protein, omega-3 fatty acids, and antioxidants such as selenium, which helps protect cells from oxidative stress. Like sardines, herring is a good source of essential fatty acids and trace minerals.

Each type of fish contributes a slightly different nutrient profile, so it's important to choose fish that aligns with your dog's individual dietary needs, life stage, and health goals. For example, dogs with dry skin or joint concerns may benefit most from fatty fish like salmon or sardines, while dogs requiring lean protein might thrive on whitefish.

The Best Fish for Dogs: Salmon

Salmon is widely regarded as the best fish for dogs for a variety of reasons. Its unique combination of high-quality protein, healthy fats, digestibility, and palatability makes it a top choice for dogs of all ages and life stages. Here’s a closer look at why salmon stands out:

High-Quality Protein:

Salmon provides a complete, easily digestible source of protein, containing all essential amino acids that dogs require for muscle maintenance, tissue repair, and overall growth.

This makes it ideal for puppies, active adult dogs, and senior dogs who need to preserve lean muscle mass. Unlike some plant-based proteins or heavily processed meats, salmon protein is highly bioavailable, meaning your dog can efficiently absorb and use the nutrients for energy, growth, and overall wellness.

Omega-3 Rich (EPA/DHA):

Salmon is naturally abundant in long-chain omega-3 fatty acids, including EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid). These fatty acids are critical for:

Skin and coat health: They help reduce inflammation, improve skin hydration, and contribute to a shiny, soft coat.
Brain function: DHA supports cognitive development in puppies and helps maintain memory and focus in adult and senior dogs.
Joint and heart health: EPA helps reduce inflammation in joints and supports cardiovascular function.

Because salmon provides EPA and DHA directly, dogs receive these benefits without needing to convert plant-based omega-3s, which is often inefficient.

Gentle on Digestion:

Salmon is a lean, easily digestible protein, making it ideal for dogs with food sensitivities, digestive issues, or allergies. Its mild flavor and soft texture are less likely to irritate the stomach or cause gastrointestinal upset compared to heavier meats like beef or pork. This makes salmon a smart choice for dogs transitioning to new foods or for those with sensitive digestive systems.

Highly Palatable:

Most dogs love the taste and aroma of salmon, which makes it particularly effective for picky eaters. Its natural flavor encourages meal acceptance, helping ensure that your dog consistently gets the nutrition they need without struggle or stress.

Quality and Sustainability:

Salmon is not only nutrient-rich but can also be sourced as a clean, premium protein from sustainable fisheries. NutriCanine uses fresh, Canadian-caught salmon, ensuring that your dog’s meals are free from unnecessary additives, contaminants, or preservatives. By sourcing high-quality salmon, we maintain maximum nutrient retention, freshness, and safety, while supporting environmentally responsible fishing practices.

Where Does Fish Come From for Pet Food

Where Does Fish Come From for Pet Food The quality of fish matters as much as the type. Low-quality fish can contain mercury or other contaminants. NutriCanine sources its salmon from sustainable Canadian fisheries, ensuring freshness, traceability, and nutrient integrity.

Canadian fisheries follow strict testing and handling procedures to maintain the quality of the fish, from water to bowl. This local sourcing reduces transport time and guarantees that dogs receive nutrient-rich, fresh salmon. Supporting sustainable fisheries also aligns with NutriCanine’s commitment to ethical and environmentally responsible sourcing.

Fresh Fish vs. Fish Meal

When it comes to dog food, not all fish ingredients are created equal. Two of the most common forms are fresh fish and fish meal, and understanding the difference can help you make informed choices for your dog’s nutrition.

Fresh Fish:

Fresh fish is minimally processed, often cooked or gently frozen soon after being caught.
It retains most of its natural nutrients, including high-quality protein, vitamins, minerals, and long-chain omega-3 fatty acids (EPA and DHA).
Fresh fish is highly digestible and palatable, making it ideal for dogs with sensitive stomachs or picky appetites.
NutriCanine uses fresh salmon from Canadian fisheries in our recipes to ensure maximum nutrient retention and freshness.

Fish Meal:

Fish meal is made by cooking, drying, and grinding fish, often from whole fish or fish by-products.
While it still provides protein, the heat-processing involved can reduce levels of heat-sensitive nutrients, like certain vitamins and omega-3s.
Fish meal is often used in dry kibble or commercial pet foods because it’s shelf-stable and cost-effective.
The quality of fish meal can vary greatly depending on the source of the fish and the processing methods used.

Nutritional Benefits of Fish for Dogs

Fish provides a broad range of health benefits that go far beyond being a simple protein source. Incorporating fish into your dog’s diet regularly can have a meaningful impact on their overall health and wellness. Some of the primary benefits include:

Promoting Skin and Coat Health: Omega-3 fatty acids in fish nourish the skin, reduce dryness and itchiness, and contribute to a shiny, soft coat. Healthy skin and fur are often indicators of a dog’s overall wellness.
Supporting Cognitive Function and Brain Development: DHA, a key omega-3 found in fish, plays a critical role in brain and eye development in puppies and supports cognitive function in adult and senior dogs.
Reducing Inflammation in Joints and Tissues: The anti-inflammatory properties of EPA help maintain healthy joints and connective tissues, which is especially beneficial for older dogs or active breeds prone to joint stress.
Aiding in Weight Management: Fish is lean and high in protein, helping dogs feel full and satisfied without consuming excess calories, supporting healthy weight management.

Let’s break these benefits down in more detail:

High Protein

Fish provides complete, highly digestible protein that contains all essential amino acids necessary for muscle maintenance, tissue repair, and overall metabolism. This makes it particularly beneficial for:

Active Dogs: Muscle recovery and energy maintenance after play or exercise.
Puppies: Support for growth, bone development, and organ function.
Senior Dogs: Helps preserve lean muscle mass and maintain mobility.

Unlike some plant-based proteins, which may lack certain amino acids or require complex digestion, fish protein is bioavailable, meaning your dog’s body can efficiently use the nutrients for optimal health. This makes fish a top choice for a protein source in fresh, balanced diets.

Low in Calories

Fish is naturally lean and low in calories, which is ideal for dogs that need to maintain a healthy weight or are prone to obesity. High-protein, low-calorie meals help dogs feel full and satisfied while avoiding excess caloric intake that can lead to weight gain.

NutriCanine’s recipes leverage the lean protein content of fish to create balanced, nutrient-dense meals. This ensures dogs get the energy they need for daily activity without unnecessary fat or fillers, making fish an excellent option for weight management and long-term health.

Source of Omega-3 Fatty Acids (EPA/DHA)

One of the most compelling advantages of fish in canine nutrition is its unique omega-3 content, particularly the long-chain fatty acids EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid). These differ from plant-based omega-3s, like ALA found in flax or chia seeds. Dogs must convert ALA into EPA and DHA, but this process is often inefficient and can result in insufficient levels for optimal health.

Benefits of EPA and DHA in dogs include:

Skin and Coat Health: EPA and DHA reduce inflammation, help alleviate dry, itchy skin, and contribute to a shiny, healthy coat. Dogs prone to allergies or seasonal shedding often benefit from regular EPA/DHA intake.
Brain Function: DHA is essential for neurological development in puppies and supports cognitive maintenance in adult and senior dogs, helping with memory, focus, and learning.
Anti-Inflammatory Effects: EPA’s anti-inflammatory properties support joint health, cardiovascular function, and overall vitality, reducing the risk of chronic inflammation that can impact mobility and quality of life.

By feeding your dog fish regularly, you provide these fatty acids in their most bioavailable, active form, ensuring that your dog receives maximum health benefits.

Best Pairings with Fish in a Skin and Coat Recipe

While fish alone provides incredible health benefits, pairing it with complementary ingredients enhances nutrient absorption and creates a more balanced meal. NutriCanine’s salmon recipe incorporates several key ingredients to maximize skin, coat, and overall wellness:

Sweet Potato: Rich in soluble fiber and beta-carotene, sweet potato supports digestion while providing antioxidants that protect skin cells and promote overall health.
Flaxseed: Adds fiber, lignans, and plant-based ALA, complementing the fish’s omega-3s and supporting healthy digestion and immune function.
Coconut Oil: Contains medium-chain triglycerides (MCTs) that enhance energy levels, improve coat condition, and aid in nutrient absorption.
Pumpkin: Packed with fiber, vitamins, and minerals, pumpkin promotes healthy digestion, weight management, and optimal nutrient uptake.
Cranberries: Rich in antioxidants, cranberries reduce inflammation, support immune function, and contribute to overall vitality.

These ingredients work synergistically with salmon to create a complete, nutrient-rich, skin and coat-focused meal. Together, they not only provide essential fatty acids and protein but also support digestion, antioxidant protection, and overall health. Dogs enjoy the flavor and texture, ensuring they receive both delicious and highly functional nutrition in every bite.
