By giving your pooch the best fish oil for dogs, you can make him a lot healthier. However, choosing the right fish oil supplement is not easy considering the number of products on the market.

That said we have created a guide to help you choose the best fish oil supplement for dogs.

What are Fish Oils?

Fish oils come from the tissues of oily fish. They contain two omega-3 fatty acids namely eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). Fish oil has been widely known to have certain health benefits to us humans. However, did you know that our four-legged best friends can also gain benefits from fish oil?

Benefits of Fish Oils For Dogs

Giving your dog fish oil can actually help him in more ways than one. That said, here are 5 ways on how fish oil can help your dog:

  • It reduces dandruff and itchy skin and eases inflammation caused by allergies. With that, the possibility of your dog getting hot spots decreases.
  • The EPA in fish oils functions as an anti-inflammatory, thus reducing the risks of inflammation of the joints which may lead to arthritis, skin, kidneys, and heart problems.
  • The DHA in fish oils can help in the development of the eyes and brain of unborn puppies by giving fish oil supplements to their pregnant mothers.
  • Fish oil can give your dog a healthy and shiny fur, not to mention it decreases shedding too!
  • It reduces the chances of your dog getting cancer.

How to Choose the Right Fish Oil for Dogs

As mentioned earlier, choosing the right fish oil for dogs isn’t that easy. After all, there are tons of products out there to choose from. To help you pick the right product, here are some questions you should ask first:

What type of fish oil is it?

It is important to know what type of fish oil product you will be giving to your dog. There are three types of fish oil currently available on the market. They’re as follows:

  • Natural Triglyceride Oil – this type of oil is the easiest to absorb inside the body, and it’s the most natural oil as well. However, it may contain contaminants due to the purification process it undergoes.
  • Ethyl Ester Oil – this type of fish oil is free of any impurities due to its concentration and distillation process, making it semi-natural with minimal levels of omega 3, EPA, and DHA.
  • Synthetic Triglyceride Oil – as the name implies, this type of fish oil is synthetic, making it hard to absorb inside the body. You should avoid purchasing this type of fish oil at all costs.

Did it come from farm fish or wild caught fish?

Fishes that were raised in farms and fishes that dwelled in natural waters have different qualities. Farm fish contains hazardous contaminants such as dioxins, insecticides, toxaphene, dieldrin, and PCBs. On the other hand, wild fish are free from those contaminants.

Was it processed with the use of ethanol?

Processing fish oil products with the use of ethanol is the cheapest method there is. However, ethanol can cause serious side effects on your dog when taken regularly. Therefore, you should strictly avoid fish oils that were processed with ethanol.

Fortunately, you can check the ethanol levels of fish oil at home by simply pouring a small amount of it inside a styrofoam cup. The fish oil is likely to contain ethanol if it seeps through the styrofoam in 30 minutes or less.

Is there a Certificate of Analysis (COA)?

A Certificate of Analysis or COA is an issued document by Quality Assurance. It is always best to ask a COA from the fish oil manufacturer as it will show all the quality control tests the fish oil product underwent along with its results.

This can help you to determine if a certain fish oil product is good, average, or bad. Fish oil manufacturers with great reputations can easily provide you with a COA.

FAQs

Q: Are there dosages to follow in giving fish oil to a dog?

A: The smaller your dog, the smaller the dose you should administer. Meanwhile, the bigger your dog is, the higher the dose you’ll have to give. Just make sure to follow the exact dosages instructed by the manufacturer according to your dog’s weight.

Q: Are there any dangers of an overdose?

A: There are no direct threats if your dog took exceeding dosages of fish oil. However, he might get diarrhea.

Q: How long until results can be noticed?

A: Usually, it takes about 3 weeks before you can see some results – sometimes even longer than that. If it’s been months since you started giving fish oil to your dog, it’s likely that the product you bought is of low quality.

Q: Which is better? Capsule or liquid form?

A: It depends on your dog. Some dogs don’t like capsules, making it hard to feed it to them. Therefore, it is much better to use a liquid form fish oil as you can easily mix it with your dog’s meals without him noticing it.

Final Thoughts

As dog lovers, we should care for the well-being of our four-legged furry friends as they also care for us. However, if your dog’s health issues seem to be getting worse, it’s best to visit a veterinarian rather than just relying on fish oil supplementations alone.
