Fish Oil Supplements Buyer’s Guide

Now that you understand what fish oils are and the possible benefits they have on dogs, the next question is how to find the right product. Sadly, there are no easy answers here. The market has plenty of fish oil brands available. 

The health needs of your pooch will determine the kind of product you choose. Nonetheless, there are still a few factors that you can use to distinguish between high-quality fish oil supplements and common ones.

What’s The EPA And DHA Concentrations?

Different products have varying concentrations of DHA (Docosahexaenoic Ccid). However, higher concentrations are not always necessary unless you are buying the oil to help improve the dog’s brain function. Besides, dogs have their natural mechanism of storing DHA in their body. Giving them more and more will not have any noticeable impact on their overall health.

Many experts believe that EPA (Eicosapentaenoic Acid) is far more vital than DHA. The reason is that dogs do not have a way of producing and storing EPA in their bodies. They have to rely on external ingestion to meet the EPA nutritional requirements. This is where the fish oil supplements come in. Additionally, EPA has other health benefits including anti-inflammatory properties.

In that case, it’s often advisable to go for products with higher EPA concentrations and lower DHA. For added convenience, you can always consider salmon dog food which is generally higher in EPA and DHA.

Are The Fish Oil Harvested From Wild Sources?

Wild fish should always be used as a source of fish oil. It is possible to use farmed fish but there are many quality concerns. You never know the kind of farming practices the farmer uses and whether they are safe for your pooch or not. Besides, it is a well-known fact that fish farms use a lot of synthetic ingredients in farming and this reduces the nutritional value of the fish oil offered by farmed fish.

That’s why you should always make sure the fish oil is sourced from wild fish. It’s prevalent to find the statement “caught in the wild” in the labels of many fish oil supplements out there. Do not take their word for it. A disturbing fact is that many products will claim they are wild but in reality, they are sourced from hatcheries. While fish from hatcheries is healthier than from farms, the purity and quality of wild fish are always highly recommended.

Apart from fish oil supplements, there are other healthy dog food options that you can consider feeding your pooch too.

Real Fish Oils

Some fish oil supplements offer additional ingredients in their formulation. Some even claim they can provide ALA which is typically converted into APA and DHA.

However, your dog’s body may lack the capacity needed to process some of these ingredients and make them useful. In that case, it is often better to go for pure fish oil. In essence, these are simply supplements that contain pure fish oil as their main ingredient. Nothing else is added. This makes it easier for the dogs to fully process the oil and benefit from it in the best way possible.

Supplementing your dog with fish oils is a great step in ensuring that your pooch has a healthy and active life. Be sure to keep them active with regular exercises such as swimming and walking.

Health Benefits Of Omega-3 For Dogs

One of the most common ingredients that you’ll find in dog food is omega-3 fatty acids. These acids also come in the form of supplements or natural sources like fish oil.

Health experts around the world have praised omega-3 fatty acids for being very beneficial to health, most especially for the heart and skin. But it is not only humans that can benefit from omega-3. In fact, a pet diet that’s rich in omega-3 fatty acids can help to protect your dog from allergies and different skin conditions.

The only way for dogs to get a good amount of omega-3 is through diet and nutrition.

Below are some of the health benefits of omega-3 for dogs.

Treats Inflammation

Omega-3 and omega-6 work together to control inflammation. While omega-6 increases inflammation, omega-3 lowers it, which maintains the balance.

If any of these nutrients go out of balance, the immune system of your dog will be in jeopardy, and it could end up suffering from various conditions associated with inflammation, including an impaired immune system.

Boosts Heart Health

Studies have shown that dogs that are getting enough omega-3 in their diet are protected against the development of atrial fibrillation, a condition characterized by irregular heart rhythm.

Furthermore, getting enough omega-3 can also minimize the risk of suffering from heart disease. This is because omega-3 works as an anticoagulant that prevents blood clots.

Improves Cognitive Function

The omega-3 fatty acids can also help to support the neurological health of your dog as well as its cognitive function. This is especially beneficial for dogs that are suffering from age-related conditions and may have challenges in mobility.

Several studies suggest that consuming a good amount of omega-3 fatty acids has a positive impact on the dog’s behavioral memory, cognitive functioning, and performance.

Prevents Dry Skin

Dogs that have unhealthy skin and poor coats are at high risk of developing skin irritation, itchiness, bacterial infections, and allergies. Supplementing with omega-3 fatty acids regularly can greatly help to improve the coat and skin of your pooch. Furthermore, it can also help to prevent the development of certain types of skin conditions, such as yeast infection and allergies.

In fact, omega-3 may also help to prevent the incidences of hotspots and get rid of dandruff. Above all, omega-3 may help minimize shedding on dogs while promoting a healthy, beautiful, and shining coat.

Helps With Joint Inflammation

Since omega-3 has anti-inflammatory abilities, studies show potential improvement in osteoporosis in dogs that exhibit lameness. Some studies also suggest objective improvement in the weight-bearing score of dogs.

The omega-3 fatty acids derived from supplements, such as flax, work by minimizing the production of prostaglandins, which is responsible for joint inflammation in dogs.

Upon observation, dogs that have plenty of omega-3 in their diet are more agile and can move freely around compared to dogs that don’t get enough omega-3.

Adding More Omega-3 To Your Dog’s Diet

Now that you know the importance of omega-3 in a dog’s diet, you’re probably wondering how much of this nutrient you should give to your dog. This will pretty much depend on certain factors, such as the age of your dog, health, and weight.

When you purchase omega-3 supplements, the label will most likely include information about the proper dosage to give to your pet. If you can’t figure out how much to feed your dog, we recommend you talk to a vet.

Aside from giving your dog omega-3 supplements, you can also feed your dog with foods that are rich in omega-3 fatty acids, such as sardines, anchovies, salmon, and trout.
