Fish Oil Supplements for Dogs have gained popularity in recent years for their potential health benefits in humans. But did you know that these supplements can also provide numerous benefits for our furry friends? In this comprehensive guide, we will explore the world of fish oil supplements for dogs. We will discuss the different types of fish oil, their health benefits, potential side effects, and how to choose the right supplement for your dog. So, let’s dive in and explore the wonders of fish oil for our beloved canine companions.

Types of Fish Oil Supplements for Dogs

Omega-3 Fatty Acids

Omega-3 fatty acids are essential for your dog’s overall body function, but their bodies cannot produce them naturally. These fatty acids, such as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), play a crucial role in cell membrane structure, energy production, and regulating inflammatory responses. They are particularly important for brain development in puppies and can aid in learning and memory. Omega-3 fatty acids can be found in cold-water fish like salmon, tuna, pollock, and trout, as well as marine microalgae.

Omega-6 Fatty Acids

Omega-6 fatty acids, including linoleic acid and arachidonic acid, have both pro and anti-inflammatory properties. Linoleic acid is a dietary requirement for all dogs, and most commercial pet diets already contain animal fats high in omega-6 fatty acids. However, adding omega-3 fatty acids to your dog’s diet helps balance the effects of omega-6, promoting overall organ health and development.

Health Benefits of Fish Oil for Dogs

Fish oil supplements offer several science-backed benefits for your canine companion. Let’s explore some of the key advantages:

Decreased Inflammation

Fish oil supplements, rich in omega-3 fatty acids, can help manage various diseases and conditions in dogs. EPA and DHA send cellular signals within the body to decrease inflammatory responses, making them beneficial for conditions like kidney disease, irritable bowel disease, and heart disease. They are also commonly recommended for aging pets to promote joint health and can provide relief to dogs with dry skin, allergies, and other skin issues.

Improved Brain Development and Cognitive Function

DHA, a component of omega-3 fatty acids, is vital for brain development in puppies. It helps them learn and retain information, aiding in their overall cognitive function. Omega-3 fatty acids can also benefit older dogs by improving brain health and reducing the effects of cognitive dysfunction, a condition similar to dementia in humans.

Slowing Tumor Growth

Studies have suggested that omega-3 fatty acids can help prevent the division and growth of certain cancer cells. With one in four dogs developing cancer at some point, supplementing your dog’s diet with omega oil may decrease the chances of severe metastatic disease.

Fish Oil Side Effects: What to Watch For

Using fish oil supplements for dogs is generally safe, but it’s essential to be aware of potential side effects. While most healthy dogs experience little to no side effects, some may develop a fishy smell on their skin and breath. Other possible side effects include gastrointestinal discomfort or oily, flaky skin when the supplement is taken in excess. If you notice any adverse effects, discontinue the use of fish oil and consult your veterinarian.

It’s also crucial to consider potential interactions between fish oil and certain medications. If your dog is taking anticoagulant medication, non-steroidal anti-inflammatory drugs, cancer medications, herbal supplements, or specialized diets targeting joint pain and skin issues, consult with your veterinarian before introducing fish oil supplements.

How Much Fish Oil Does Your Dog Need?

The appropriate dosage of fish oil for your dog depends on various factors, including their age, breed, weight, diet, and overall health. Some commercial dog diets already contain omega oil, so be mindful not to overdose your pet by adding additional supplements.

To determine the correct dosage, consult your veterinarian. They will consider your dog’s body weight and type before recommending the appropriate amount. As a general guideline, dogs taking fish oil for osteoarthritis pain can receive 75 mg to 100 mg per kilogram of body weight daily. For instance, a 50-pound dog may need approximately 2270 mg of omega oil on a daily basis.

Liquid fish oil supplements usually come in soft gel form, with recommended daily dosing provided on the label. If your pet resists taking pills, the soft gels can be punctured, and the oil can be poured over their food for a tasty treat.

How to Choose the Right Fish Oil Supplement for Your Dog

With numerous options available, choosing the right fish oil supplement for your dog can be overwhelming. It’s crucial to avoid giving your dog human fish oil supplements, as they may contain ingredients and amounts that are harmful or toxic to dogs. Here are some guidelines to help you make an informed decision:

  • Veterinary-formulated and/or veterinary recommended: Look for supplements that are formulated or recommended by veterinarians.
  • Manufacturing: Choose a supplement made in the USA at a Good Manufacturing Practice-certified (GMP-certified) facility to ensure quality control.
  • Clean ingredients: Opt for supplements with clean and natural ingredients.
  • Sustainable sourcing: Look for supplements formulated with omega-3 fatty acids from sustainably sourced fish like wild-caught pollock or wild Alaskan salmon oil.
  • Preservatives: Check if the supplement contains natural preservatives like vitamin E.
  • Free from fillers and artificial additives: Avoid supplements with fillers or artificial additives.
  • Clearly labeled: Ensure that the ingredients, amounts, and expiration date are clearly labeled.
  • Palatability: Choose a supplement that is palatable for your dog to ensure easy administration.
  • Clear dosing instructions: The supplement should come with clear dosing instructions to help you administer the correct amount to your dog effectively.

One excellent option that ticks all the boxes is Native Pet’s Omega Oil. This high-quality fish oil supplement is formulated specifically for dogs, promoting skin health, a healthy coat, and healthy joints. It is made in the USA at a GMP-certified facility, contains clean ingredients, and is sustainably sourced from wild-caught pollock and wild Alaskan salmon oil. Its palatable nature makes it easy to administer, and the clear dosing instructions ensure accurate usage.


Fish oil supplements can be a valuable addition to your dog’s diet, providing numerous health benefits. From reducing inflammation to improving brain function and potentially slowing tumor growth, omega-3 fatty acids offer a range of advantages for our canine companions. However, it’s important to consult your veterinarian before adding any supplements to your dog’s regimen. With their guidance, you can choose the right fish oil supplement that meets the highest standards of quality and safety. So, give your furry friend the gift of fish oil and help them lead a healthy and happy life.
