Dog Fish Oil Buying Guide

Fish oil is a very helpful supplement for dogs that provides many internal and aesthetic health benefits. Not only does fish oil give your dog a bright, shiny coat, but it also can improve your dog’s stamina and reduce inflammation. Fish oil contains omega-3 fatty acids, which are important for dogs, humans, and many other animals.

Fish oil can also be used as a treatment for many conditions, particularly arthritis and high cholesterol, and used to slow cancer growth and manage serious heart problems. Dogs don’t typically get fish oils in their diet naturally, so it’s helpful to give them a fish oil supplement on a regular basis to ensure they’re getting this important nutrient.

There are many fish oil supplements on the market for dogs today. Choosing the best one can be difficult, particularly if you’re not sure what to look for. Here are some things to take into consideration when shopping for a fish oil supplement for your dog.

Oil Type

The first thing to look at is the oil type you’re giving your dog. There are three types of fish oil supplements. All of them contain important acids that will benefit your dog’s health. Natural triglyceride oil is very easy for dogs to absorb, but it’s not purified and may contain contaminants. Synthetic triglyceride is completely manufactured, and while contains no contaminants, it’s more difficult for dog’s bodies to absorb.

The healthy balance between these two options is ethyl ester oil, which is a natural oil that’s been distilled to remove impurities. This is still relatively easy for dogs to absorb, but doesn’t contain potentially problematic contaminants. Since this type of oil is easier for dogs’ bodies to process, they’ll reap the benefits of it more quickly and obviously.

It’s very important that your dog gets a high enough dosage of fish oil to see results. Many dog owners complain that they don’t see the benefits of this supplement, but that’s typical because small amounts of fish oil are essential to healthy dog nutrition anyway. When shopping for a supplement, you should look for the amount of EPA in each dose.

EPA is one of the major active acids in a fish oil supplement. In general, your dog should be getting at least 20 milligrams of EPA per pound of body weight. That means if your dog weighs 30 pounds, for instance, they should be getting at least 600 milligrams of fish oil to see results.

Be sure to check the full nutrition label on the back of the bottle for the total amount of EPA in each dose, as the advertising on the front of the bottle may be confusing or misleading.

If the supplement comes with very small doses, the amount you’ll have to use to see results may not be cost-effective. On the other hand, it’s also important to make sure you don’t overdo it, as too much fish oil can be very dangerous for dogs. If you’re unsure of exactly how much to give your dog, consult with your vet before starting the supplement.

Ingredient Ratios

The two major acids found in fish oil supplements for dogs are the previously-mentioned EPA and DHA. Both are very helpful for your dog’s overall health, but studies have shown that EPA is more effective for reducing inflammation, which is what leads to reduced joint and muscle pain as well as increased stamina and energy.

Therefore, you’ll want to look for a supplement that’s higher in EPA than DHA. However, both acids should still be present in the supplement. Some fish oil supplements also contain additional ingredients to nourish the dog’s coat and skin or supplement their diet. Check the full ingredients list on the back of the bottle to learn exactly what’s in the supplement.

Liquid vs. Capsule

There are two types of fish oil supplements available – liquid and capsule. Both have their pros and cons. Capsule supplements aren’t messy to give to your dog and can be given to them either directly or with their food. Many capsules come as soft chews, which mimic the texture of dog food, making them easy for dogs to eat. However, not all dogs like taking capsule supplements.

If your dog does not like capsules, a liquid supplement might be easier. Liquid supplements can be added to wet food without much change in texture or taste, so your dog will be less likely to notice a difference. However, liquid supplements can get messy, particularly if your dog is a fast or sloppy eater to begin with. The best option for your dog will mostly depend on personal preference.
