Buying Advice: Deciding on the Finest Fish Oil for Fido

In other words, what exactly are omega-3 fatty acids?

When you hear the name “omega-3 fatty acids,” your first thought might be “fat isn’t good,” but you’d be wrong. Polyunsaturated fats are where you’ll discover the omega fatty acids (one of the good kinds of fats). These fatty acids are used to manufacture hormones that have a role in controlling inflammation and blood flow. You’d think everyone would have one of these lying around, but they’re really rather rare. Consequently, foods like flaxseed and fish oil that naturally contain them are very important for us and our dogs.

Not only are omega-3 fatty acids beneficial for this, but they also have many other uses. They are beneficial because they counteract the omega-6 fatty acids that are prevalent in processed and refined meals. There are excessive amounts of omega-6 fatty acids in many commercial dog meals, and your dog probably has the same problem (and they do need some omega-6, just not an overabundance).

Why Is Giving Your Dog Fish Oil A Good Idea?

Injecting fish oil into your dog has several potential health advantages.

Benefits

  • Fish oil’s high concentration of omega-3 fatty acids is fantastic news for your dog’s hair and skin, since these fats have been shown to reduce dry skin-related irritation and enhance the natural luster of your pet’s coat. A pleasant byproduct of enhancing your dog’s skin health? Perhaps it will lessen the amount of hair that falls out!Dogs’ Immune Systems: They get into some nasty stuff! (like the garbage).. That means they’re exposed to microorganisms all the time.
  • Your pet’s immune system will benefit from the omega-3 fatty acids you feed them, making it more robust and better able to fend off any potential infections. In addition, if the fish oil your dog is getting includes salmon, that’s even better! The astaxanthin in salmon has been linked to a variety of health advantages, including a reduced risk of cancer in dogs.
  • Including fish oil supplements in your dog’s food has the same heart-healthy effects as including them in a human’s diet. The cardiac muscle can be strengthened and the risk of arrhythmia can be decreased thanks to the positive effects of omega-3 fatty acids.
  • Due to the anti-inflammatory properties of omega-3 fatty acids found in fish oil, it is a great supplement for any dog with joint problems. When it comes to arthritis, not only may this reduction in inflammation assist lower discomfort and increase mobility, but studies indicated that dogs using fish oil were able to use less of their arthritis medication.
  • Elbow and hip dysplasia may also benefit from fish oil. When your pet’s joints do not grow normally, this is known as dysplasia. Joint discomfort, swelling, and instability are the end results of cartilage destruction. Fish oil is not a treatment, but it can help alleviate some of the inflammation that brings on the symptoms.
  • Because of their importance in the development of a puppy’s brain, omega-3 fatty acids are commonly administered to pregnant dogs. However, the benefits aren’t limited to canine companions. DHA levels are often reduced in older dogs with cognitive impairment syndrome.Studies indicated that symptoms of cognitive dysfunction syndrome might be ameliorated with the use of fish oil containing DHA.

Concomitant Risks

It is possible that fish oil, like any other supplement, might cause certain unwanted reactions. It’s important to be aware of these things, because they might not manifest in every dog.

  • Having an upset stomach is common when trying new foods with your pet, especially if your pet has a very sensitive stomach. Fish oil, being mostly fat, can sometimes induce a slight case of diarrhea in dogs, although this usually clears up soon. Stop providing your pet fish oil immediately if the diarrhea doesn’t improve or worsens, and see your vet about appropriate dosing.
  • Extremely rarely, some canines may have an allergy to certain types of fish, which would make fish oil produced from such fish unsafe for them to consume. If this happens, your pet’s skin or fur may become itchy, and their overall appearance may suffer.
  • Fish oil may cause your pet’s blood to thin since omega-3s reduce the likelihood of blood clots. This isn’t normally a problem, though (and may even improve heart health). But if your dog is bleeding from an injury, things may get tricky. Do not administer fish oil to a dog if it is currently taking anticoagulant medicine.
  • Fish oil for dogs is just as effective as it is for people. Because of this, the fatty acids in fish oil may not be suitable for dogs who are already taking other medications. Before giving your pet any kind of supplement, you should always check with your veterinarian.

How Should I Keep Fish Oil?

Fish oil storage is a breeze. It will go bad if exposed to oxidation, so keep it out of the sun, heat, and air. Fish oil should be kept in the fridge if you want to keep it in its optimal state.

Fish Oil for Dogs: What to Look For

As with whatever your dog eats, you should only give them the best. For this reason, the following are important considerations when selecting a fish oil for your dog.

Ingredients

You may get fish oils for dogs that are created with a wide variety of components. Some will be made entirely from salmon, some from salmon and pollock, and yet others from a broad variety of fish.

Unless your dog has a fish allergy, you may feel safe giving him fish oil made from any fish. However, you will discover that the ones made from 100% salmon have far more omega-3 fatty acids and astaxanthin.

Vitamins (particularly Vitamin E) and antioxidants are added to some fish oils to increase their efficacy. To make fish oil more palatable, some manufacturers add flavour to it.

The level of purity and requirement for extra nutrients like vitamins and antioxidants in your dog’s food are also factors you’ll have to weigh. It’s also crucial to know what’s in the fish oil in case it has an adverse reaction to your pet’s other treatments.

Intake of Omega-3 Fatty Acids

We’ve already established that not all fish oils are the same. There will be those with very high concentrations of EPA and DHA and those with considerably lower concentrations. The more value you can extract from your expenditures, the better.

Form

Canine fish oil supplements are most commonly found in liquid or softgel form (but occasionally as a chew). You are the best judge of the easiest delivery method since you know your pet best.

Pills are often less odorous, although not all dogs will consume them (no matter how much peanut butter or other deliciousness you put on them).

Testing

Pet food and supplements are subject to significantly less stringent regulation by the FDA than human food and supplements are.

That’s why it’s crucial that you pick a product that’s been independently verified for its authenticity and safety. Similarly, you may ensure that the fish oil you’re contemplating has passed rigorous requirements by looking for The NASC Quality Seal.

Price

Supplements, whether for humans or canines, may be rather pricy. In certain cases, you may find many products with the same set of components, etc., that sell for dramatically different rates.

Reviews

You may learn a lot about a product’s quality and advantages from reviews written by other pet owners who have tried using it. Remember that even the highest-rated product might fail to please your dog because every dog is unique and has a distinct reaction to food and supplements.

Conclusion

Grizzly Omega Health Omega-3 is our top pick for the best fish oil for your dog because it has the NASC seal of approval and is fortified with vitamins and antioxidants.

In the end, Zesty Paws is our top pick, as it’s made with 100% pure salmon oil and flavored to whet your dog’s appetite. BestForPets (bestforpets.org) hopes you can find the best fish oils for dogs for your pet.
