Recommended Dosage of DHA and EPA in Fish Oil for Dogs

As fur parents, we constantly seek ways to enhance the well-being of our furry companions. The quest for optimal pet health is ever-evolving, from selecting a proper diet to ensuring enough exercise. 


One supplement that has gained significant attention in recent years for its potential benefits is fish oil. It is an excellent omega-3 source for dogs and is a valuable addition to their diet, offering various health advantages.


This blog discusses the importance of fatty acids in a dog’s diet, the beneficial world of fish oil for canines, and the recommended dosage for your pet.

What are Fatty Acids?

Fatty acids are building blocks of fat, a crucial component of every cell in the body. They are classified into two main categories: saturated and unsaturated. The former is generally associated with health risks in excessive amounts, while the latter are deemed essential for a dog’s well-being.

Omega-3 Fatty Acids

Omega-3 fatty acids are polyunsaturated fats crucial in maintaining optimal dog health. There are three main types of omega-3 fatty acids, namely, eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), and alpha-linolenic acid (ALA).


There is an abundant supply of DHA and EPA in fish oil, offering a wide array of health benefits. It supports cardiovascular health, promotes a shiny coat, and bolsters the immune system. Additionally, they have anti-inflammatory properties, which are beneficial for dogs suffering from arthritis and allergies.

Omega-6 Fatty Acids

The key components of omega-6 fatty acids are linoleic acid and arachidonic acid. Vegetable oil, poultry fat, and certain grains are the primary sources. Adding these foods to your dog’s diet can aid skin and coat health, regulate metabolism, and support the immune system.

Importance of Fatty Acids in a Dog’s Diet

Include fatty acids in your dog’s regular meals to reap its benefits.

Protects the heart

Just as in humans, heart health is a critical concern for dogs. Omega-3 fatty acids help maintain cardiovascular health. They regulate blood pressure and support overall heart function, contributing to a longer and healthier life for your canine companion.


Research has found that fish oil can decrease the heart's susceptibility to developing an irregular rhythm known as atrial fibrillation. Moreover, it possesses anti-coagulant properties that help prevent the formation of blood clots.

Provides support for dry, flaky skin in allergic pets

Regarding allergic pet skin conditions, omega-3 and omega-6 act as potent allies that address the root causes and relieve symptoms. For instance, omega-6 fatty acids contribute to forming ceramides, which help the skin retain moisture. It helps restore the skin barrier function and prevents further water loss.


Meanwhile, omega-3 fatty acids, notable DHA and EPA in fish oils, contribute to the skin's structural integrity. They promote the formation of healthy cell membranes and enhance the skin’s overall strength and resilience.

Boosts joint function and mobility

Manage your pet’s joint issues, such as arthritis, by providing it with a source of omega-3 fatty acids. They possess anti-inflammatory properties that reduce inflammation and support joint lubrication. Improved mobility and reduced discomfort are highly beneficial, particularly in aging or active dogs prone to joint stress.

Enhances immunity

The two fatty acids are crucial in supporting your dog’s immune system. Omega-3 enhances the immune response, allowing your pet to resist infections and illnesses better, while omega-6 contributes to producing immune cells that ensure a robust defense against pathogens. 

Symptoms Your Dog Needs EPA or DHA

There are various effects on your pet’s mental and physical health when deficient in essential nutrients, such as EPA and DHA fatty acids. One of the most common effects is depression and being out of sorts, as the lack of these fatty acids is linked to cognitive issues.


Apart from behavioral signs, EPA or DHA deficiency also results in various symptoms physically, such as the following:


  • Dull or poor coat
  • Slow wound healing
  • Hot spots
  • Allergies
  • Dull and flaky skin
  • Ear infections
  • Kidney issues

Recommended Dosage of Omega-3 Fatty Acids for Dogs

While providing omega-3 sources for dogs offers many benefits, it’s important to administer the correct dosage to ensure optimal results without any adverse effects. After all, too much of a good thing can be overwhelming and harmful.


The recommended dosage depends on different factors, such as your dog’s size, age, and health status. We recommend consulting a veterinarian before introducing this new supplement to your dog’s diet.


Overdosing can lead to various side effects, such as vomiting and diarrhea, delayed wound healing, and weight gain. You also put your pet at risk of an altered immune system and a higher chance of reduced blood clotting. 


Dosage charts and general suggestions should be taken with a grain of salt. However, here are general guidelines to help you get started.

Small dogs (up to 20 lbs)

  • EPA/DHA: 150-200 mg/day
  • Fish oil capsules: 500 mg - 1,000 mg/day (one capsule every two days)

Medium dogs (20-50 lbs)

  • EPA/DHA: 250-500 mg/day
  • Fish oil capsules: 1,000 mg - 2,000 mg (one to two capsules per day)

Large dogs (50-100 lbs)

  • EPA/DHA: 500-1,000 mg/day
  • Fish oil capsules: 2,000 mg - 4,000 mg (two to four capsules per day)

Extra large dogs (100+ lbs)

Keep Your Pup in Its Best Condition

In the intricate world of dog nutrition, fatty acids emerge as essential threads that weave various aspects of health and well-being. From promoting a shiny coat to supporting joint health, cardiovascular function, and cognitive abilities, these fatty acids are unsung heroes.


As responsible pet parents, let’s ensure that our furry friends receive the nutritional care they deserve by recognizing and incorporating the vital role of fatty acids in their daily diet. A nourished and thriving dog is a testament to the power of a well-rounded, fatty acid-rich diet that nourishes them from within.
