Best Fish Oil For Dogs: Benefits, Cons, And The Top 5 Products!

Best Fish Oil For Dogs

I was recently in a conversation with a good friend of mine - let us call her Kelly – who happens to be a pet lover.

She owns all kinds of pets and on hearing that she had a variety of dogs, our conversation slowly steered towards dog diets.

In the midst of this conversation, I asked her if her dog’s diet included fish oil.

The expression of utter bewilderment on her face at that point in time is one that I will not forget in a hurry.

Her expression shrieked “why on earth would I add fish oil to my dog’s diet?”.

Unfortunately, this is not an uncommon reaction.

I would not say the majority, but there are quite a few people out there who echo such sentiments.

It is not that the benefits of fish oil are not known.

There has been a lot of buzz about the research of fish oil and its results.

It is quite clear to most people that fish oil benefits human beings.

However, what is not as well known is that it can also help dogs.

In a nutshell, an ideal diet for dogs should have the right kinds of fats – fish oil being one of them. In the wild, dogs (and for that matter, cats too) get considerable amounts of fish oil in their diets.

This clearly has a positive effect on their health.

We will go over the benefits in more depth at a later point in this article, but suffice to say that adding the best fish oil for dogs to your pet’s diet would go a long way in keeping them healthy.

This article will take you through virtually every single detail you need to be aware of when it comes to the best fish oil for dogs.

Why Is Fish Oil For Dogs Important?

Oh my Lord! I’ve never tried this but tastes great to be honest.

The more avid readers of you may have noticed that fish oil supplements have received more attention of late than they have at any time in the past.

It is common knowledge that there seems to be a positive correlation between taking fish oil supplements and healthier heart and brain function in human beings.

The good news for dog owners is that it turns out dogs may very well benefit from regular consumption of fish oil.

The best fish oil for dogs is beneficial to a dog in a myriad ways – it will help bolster its immune system, it will help in keeping its skin smooth and shiny, it is beneficial for joints, kidneys, heart, etc.

The primary component of fish oil that should be credited for all the aforementioned benefits is the omega-3 fatty acid.

Without getting too technical, Omega-3 fatty acids are made out of a couple of long-chain acid forms.

These are called DHA and EPA.

The former is imperative for the health of brain tissues, retina, etc.

The latter helps prevent inflammation of the skin, heart, kidneys and joints.

Among those pet owners who know that fish oil for dogs would be beneficial, there is still some confusion about the primary differences between fish oil, salmon oil and krill oil.

Let us briefly list them here:

  • Fish oils have a much longer shelf life than krill oils.
  • Krill oils constitute astaxanthin, an antioxidant that is not usually present in the regular fish oil.
  • Salmon oil is derived only and wholly from salmon. The difference is that fish oil is derived from myriad types of fish such as salmon, sardines, trout, etc.

Frequently Asked Questions (FAQs)

Fish oil for dogs: Frequently Asked Questions

How Much Fish Oil Is Safe For Dogs?

As we have already looked at, too much fish oil is potentially detrimental to your dog’s health.

While the dosage differs from dog to dog depending on a number of factors, as a general rule of the thumb 20-55 mg of DHA+EPA per 1 pound of your dog’s body weight should be safe.

It is always prudent to check with your vet.

Are Wild Caught Fish Better Than Farmed Fish?

Yes, you will find that the best fish oil for dogs typically come from wild fish which grew in their natural environment.

The fish that are farmed or raised in factory farms tend to contain a large number of harmful toxins.

Liquid Form Or Capsule Form: Which Is Better?

There is no right or wrong answer to this, hence why both liquid fish oils and capsule forms of fish oils have been included in the list here.

If your dog needs a dosage of fish oil that varies every so often, then liquid fish oil may be preferable.

Conversely, if the dosage is fixed, then a capsule might be a better option.

The one advantage that liquid fish oil has on capsule fish oil is that it is absorbed faster.

I would suggest trying both out (after consulting a vet) and choose whichever one your dog seems most comfortable with, as that is the most important factor.
