Fish oil may sound like an odd supplement to add to your dog’s daily diet and you may think, why not just eat fish straight? However, fish oil is a way more concentrated source of great benefits that will contribute to your pup’s overall health. If you want to improve your dog’s joints, brain function, and skin condition, it’s worth exploring fish oils to see they could work for you and your pup.

Moreover, high-quality fish oil supplements do offer many benefits, but there are many products on the market and not all are made the same. So, we’ve created a guide to help you know the truth about fish oil supplements to choose the best one for your dog’s needs.

What is Fish Oil?

In fish oil, there are three types of dietary fats: saturated fats, monounsaturated fats, and polyunsaturated fats. Omega fatty acids are found in these fats and they manufacture important hormones that are not naturally in the body.  Omega-3 is found primarily in cold-water fish, shellfish, plant and nut oils, and flaxseed. A lot of dog food companies use refined oils like soybean oil, which are high in omega-6. Your dog ends up with too much omega-6 and not enough omega-3 fatty acids. That is why fish oil supplements can benefit and balance the right amount of fatty acids.

Furthermore, fish oil supplements for dogs can be found in liquid form or in tablet form. With a huge amount of fish oil supplements on the market, they are two different kinds: regular fish oil and salmon oil. Salmon oil contains omega-3 fatty acids that are extracted from salmon, whereas fish oil comes from various different cold-water fish.

Why Fish Oil is Good for Dogs

If your pup is eating foods high in grains, meat from non-grass-fed animals, and vegetable oils, fish oil can be very beneficial to provide omega-3 fatty acids that their body needs. Depending on your dog’s diet and general health, fish oil supplements might become a long-term plan or just a temporary addition to their diet.

Fish oil for humans have been a top nutritional supplement for the last several years. In fact, as diets move away from natural foods and more toward processed foods, we no longer receive the benefits from omega-3 fatty acids. Our bodies need a balance in both omega-3 and omega-6 fatty acids, and the same is true for our dogs. This is why including fish oil in your dog’s diet is great health benefit.

Dogs need polyunsaturated fats, omega-3 and omega-6 in their diet for many reasons including:

  • Hormones in omega-6 increases the immune response and cell growth
  • Omega-3 balances the properties of omega-6 and has anti-inflammatory properties to help treat conditions like allergies, arthritis, and other inflammatory diseases
  • Omega-3 also improves skin and coat health, joints, and energy levels
  • Improvement in cognitive development in puppies and cognitive function in older dogs

With so many options of fish oil supplements out there, it can be difficult to know which one is best for your pup. Here are some important facts about fish oil that may help you decide.

There are three types of fish oil supplements:

  • Natural triglyceride oil: The most natural and easiest for dogs to absorb. However, because it isn’t purified, it may contain contaminants like PCBs.
