What to Look for in Fish Oil for Dogs

Before buying fish oil for your dog, it is important to consider several features that greatly affect the quality and effectivity of the fish oil. Below is a list of some things that you should look for in fish oil for your dog:

1. Fish Oil Source: What fish?

A good fish oil for dogs indicate on its label the source of the fish oil – what kind of fish was used. Before going into the most common fishes that are used to make fish oil, here are important things that you have to know:

  • Eicosapentaenoic acid (EPA)
  • Docosahexaenoic acid (DHA)

EPA and DHA are converted types of omega 3 that are found in some fish. The combination of two bring benefits such as slowing down of age-related memory loss, support learning and attention, and promote healthy brain function and well-being.

They also promote metabolism of cholesterol and dietary fat, reduce risk of obesity, and help maintain a healthy triglyceride level. When choosing a fish oil for you dog, it is better to go for those that have a higher ETA and DHA content.

  • Mackerel, Sardine, Herring, Anchovy: 18% EPA and 12% DHA
  • Salmon: 10% EPA and 11% DHA
  • Cod Liver: 9% EPA and 11% DHA
  • Krill: 11% EPA and 5% DHA
  • Pollock: 6% EPA and 12% DHA

2. Fish Oil Source: Farmed Fish or Wild Caught?

Whether the fish were farmed or wild caught, will tell you so much about the quality of the fish oil. Fish that are raised or cultured in factory farms are usually overcrowded and polluted. They are also usually fed with fish pellets that may bring concentrated toxins in their bodies.

Many fish farms also incorporate antibiotics into the water. Researchers analyzed and compared data from both farmed fish and wild caught salmon from different regions around the world.

They found out that farmed salmon contained dangerously high levels of polychlorinated biphenyls (PCB’s) that are very toxic and carcinogenic. They also found many other harmful toxins.

Choose fish oils that use wild caught fish that had grown up in their natural environment. They are less contaminated and have little to no toxins.

3. Fatty Acids and Other Nutrients

A good fish oil will market their content of omega 3 and omega 6 fatty acids. These are the most important to look for in fish oil, because obviously, these fatty acids are most probably the main reason why you are giving fish oil to your dog.

Many other good fish oil also include additional vitamins. Although these may be a bit more expensive, the benefits of additional vitamins will most likely outweigh the cost.

4. Liquid or Capsule

It has been a common dilemma for dog owners if they should give their dog fish oil in the form of liquid or capsule. There are three considerations that must be taken into account when making a decision: 1) the preference of your dog, 2) the needed dosage or strength, and 3) the absorption.

a. Dosage: Flexibility
Liquid

Liquid fish oil is ideal for those dogs that may have a varying dosage requirement.

There is no added hassle of cutting capsules when you need a lower or a higher dosage of fish oil.

Capsule

It may be difficult to adjust the serving size or the dosage of fish oil capsules.

b. Absorption: Efficiency
Liquid

Liquid fish oil can be absorbed faster by your body.

It takes only around 1 to 4 minutes for your body to absorb the liquid fish oil.

Capsule

Fish oil capsules have to be broken down by the body first before it gets absorbed.

Thus, it may take about 30 minutes for the body to assimilate capsule fish oil.

Based on the discussion above, liquid fish oil is better when it comes to flexibility and efficiency. Most dog owners also claim that their dogs prefer liquid fish oils than capsules, as perhaps they are easier to intake.

5. Smell and Taste

If you want an easier and more successful attempts of giving fish oil to your dog, a good smell and an appetizing taste are a must. Read reviews about what other dog owners and other canines think about the smell and taste of certain brands of fish oil.

6. Free from Contaminants

Always check the labels to make sure that the fish oil is free from harmful toxics, such as mercury.

7. Veterinarian Approval

Not all fish oil is veterinarian-approved or veterinarian-recommended, but, good fish oil products are. This is one great assurance that the fish oil is medically tested and proven to be safe for dogs.

If some fish oil products do not explicitly say that they are veterinarian-recommended, do a quick but thorough research about what veterinarians say about it.
