Science on the benefits of fish oil for dogs

We already know that giving fish to dogs is a good idea. But what many people may not be aware of are all the proven benefits of fish oil for dogs. While it improves dog's overall health, it also helps canines with skin and coat problems. For example:

Why giving fish oil for dogs is a good thingThe main component of fish oil responsible for the many benefits are omega-3 essential fatty acids – a powerful agent.

Omega-3s are made out of two long-chain acid forms called EPA and DHA, which are responsible for most of the health benefits and improvements in dog's brain function, aiding their eye health and a lot more. For example, DHA is one of the building blocks for the of tissues in the brain and the retina of the eye, but there's a lot more to it.

Here are several more papers on the benefits of fish oil and omega-3 for dogs:

Most dogs can use additional omega-3 fatty acids in their diet, but some diets provide plenty of them. For example, some  homemade dog food recipes tend to include a lot of omega-3's, and some commercial dog food diets contain omega-3s in their formula.

The Best Fish Oil for Dogs SupplementsHow much fish oil for dogs is safe?

While fish oil for dogs provides a lot of benefits, giving too much omega-3's to dogs is not good, and can be detrimental to their health. Before giving any fish oil to your dog, please check with your veterinarian to see if this supplement is appropriate in your pet's diet.

The National Research Council has established the right fish oil dosage for dogs based on how much EPA and DHA is safe for canines to handle. This is how much fish oil for dogs is best to give in one dosage:

20-55 mg of EPA/DHA (combined) per 1 lb of dog's body weight

For example, if your dog weighs approximately 30 lbs, then you should give him a single dosage of 1,000 mg of fish oil, which should contain approximately 300 mg of EPA/DHA (combined). If your dog is suffering from a serious disease, dosage may need to be raised, but you should discuss this with your veterinarian.

Further details about how much fish oil for dogs is to be given will also be included on the package of the supplement that you purchase under the “fish oil dosage for dogs.” Make sure to read the instructions and follow them, unless otherwise specified by your vet.

Fish oil capsules for dogs vs liquid fish oil for dogs

Some pet owners are confused which one is better – fish oil capsules for dogs, or liquid fish oil for dogs supplements like Grizzly Salmon Oil. The truth is neither is superior or inferior to the other: they all contain the same thing.

Your choice will mostly depend on convenience and price. Usually, liquid fish oil is easier to give to dogs because you can simply put it into their meal. Fish oil capsules for dogs may sometimes be more difficult to give, but using pill pocket treats can help.

Additionally, there is an argument that the absorption of liquid fish oil for dogs is better or quicker when compared to fish oil capsules for dogs which are made with coating, but the difference is probably so minuscule that there's no reason to worry about it. The important thing is to give fish oil for dogs if you believe they may benefit from it; what form you use should not be a determining factor.
