Buyer’s Guide – Choosing The Best Fish Oil For Dogs

What Are Omega-3 Fatty Acids?

While omega-3 fatty acids may seem bad—after all, who wants to eat fat?—they are really beneficial. Polyunsaturated fats include omega fatty acids (one of the good kinds of fats). These fatty acids play a crucial role in the production of hormones that control blood flow and inflammation. While you’d assume that we’d all have some of them laying around, they are not present in our bodies naturally. Because of this, it’s essential that we (and our dogs) ingest items like flaxseed and fish oil that contain them.

Yet omega-3 fatty acids are useful for more than just that! They are beneficial for our bodies because they help counteract the omega-6 fatty acids, which are mostly present in cereals and processed meals. Many dog meals contain far too much omega-6 fatty acids, which means your dog also does (and they do need some omega-6, just not an overabundance).

Why Is Giving Your Dog Fish Oil A Good Idea?

Feeding fish oil to your dog may have a lot of positive health effects!

Benefits

  • Healthy Coat & Skin: Fish oil is rich in omega-3 fatty acids, which is fantastic since they may help make your dog’s coat very lustrous and lessen itching brought on by dry skin. Added benefit of enhancing your dog’s skin condition? It could lessen shedding!
  • Immune system: Our dogs sometimes come into contact with some really unpleasant things (like the garbage).. This implies that they are constantly exposed to microorganisms. Fortunately, omega-3 fatty acids strengthen your pet’s immune system, making it simpler for them to fight off any ailments that may arise. And much better if the fish oil you’re feeding your dog contains salmon! Astaxanthin, an antioxidant found in salmon, offers some pretty awesome advantages for the immune system of your dog (and may even help prevent cancer!).
  • Healthy Heart: Adding fish oil supplements to your dog’s food may have similar heart-healthy advantages as adding them to a human’s diet. Omega-3s provide a number of advantages, including lowering the risk of arrhythmia and strengthening the heart muscle!
  • Improved Joint Function: Fish oil is a fantastic supplement to the diet of any dog experiencing joint problems since it includes omega-3 fatty acids that may help decrease inflammation. When it comes to arthritis, not only can this decrease in inflammation aid minimize discomfort and increase mobility, but studies revealed that dogs using fish oil were able to use less of their arthritis medicine. Fish oil may also assist with elbow and hip dysplasia. When your pet’s joints don’t grow properly, it’s called dysplasia. As a consequence, the cartilage in the joints degrades, resulting in swelling, discomfort, and limping. Although fish oil isn’t a panacea, it may help lessen the symptoms of inflammation.
  • Healthy Brain: Omega-3 fatty acids are often provided to pregnant dogs since they are crucial for the healthy development of the pups’ brains. But not only pups can profit from this! DHA levels in older dogs suffering from cognitive dysfunction syndrome are often decreased. Yet, research showed that symptoms of cognitive dysfunction syndrome might be lessened when administered fish oil containing DHA!

Potential Side Effects

Like any supplements, fish oil might have certain negative effects. While they won’t always happen in all dogs, you should look out for them.

  • Upset Stomach: If your pet has a sensitive stomach or is given something new to try, they may have stomach problems. Moreover, really fatty diets (and fish oil is largely a fat) might give dogs minor diarrhea that goes away soon. Talk to your veterinarian regarding dose quantities and stop providing your pet fish oil right away if diarrhea doesn’t cease quickly or isn’t a minor case.
  • Food Allergy: While it is uncommon, some dogs may have allergies to certain fish species, rendering them sensitive to fish oil made from such fish. If this is the case, your pet may begin to have unhealthy-looking fur or have itching skin.
  • Blood Thinner: Since omega-3 fatty acids may stop blood from clotting, fish oil may make your pet’s blood thinner. Normally, this isn’t a problem (and may even improve heart health). Nevertheless, it can become a concern if your dog sustains an injury and starts bleeding. Also, avoid giving fish oil to dogs who are currently on blood thinners!
  • Contraindication: Fish oil for dogs has the same effects as it does for people. As a result, there may be times when the fatty acids in fish oil and a prescription your dog is currently receiving don’t combine well (especially anti-inflammatory drugs). Before giving your pet any vitamins, be sure to see your veterinarian.

How Do I Store Fish Oil?

Fish oil storage is a straightforward process. It must be shielded from intense heat, light, and air as oxidation may cause it to go bad. You must keep fish oil in the refrigerator to do this.

What To Look At In A Fish Oil For Dogs

When it comes to anything your dog will be consuming, you want to be sure you’re buying them the best. Because of this, you need to consider the following while purchasing fish oil for your dog.

Ingredients

Different fish oils for dogs are manufactured from various substances, as you’ll discover. Some may have just salmon, while others may contain both salmon and pollock, yet others will contain a variety of fish. If your dog doesn’t have an allergy, any kind of fish oil should be safe, however the ones that are 100% salmon will generally have greater concentrations of omega-3 fatty acids and astaxanthin.

Moreover, some fish oils include extra vitamins (particularly Vitamin E) and antioxidants to provide additional benefits. To make fish oil more palatable to your pet, flavour may sometimes be added.

You must choose the level of purity you desire for the product and if your dog needs additional vitamins or antioxidants. Understanding the components might help you determine how a fish oil can affect the drugs your pet is taking.

Omega-3 Fatty Acid Levels

Not all fish oils are created equal, as we have said. Although some will have far lower quantities of EPA and DHA, others will have exceptionally high levels. The greater the value for your money, the more.

Form

Several kinds of fish oil are available for dogs, mostly as a liquid or a softgel (but occasionally as a chew). When you are familiar with your pet, you will be able to determine which form will be easiest for them to eat. Although medications often have less odor, some dogs won’t take them (no matter how much peanut butter or other deliciousness you put on them).

Buy Pets Supplies on Amazon

Testing

The FDA controls pet food and supplements far less strictly than it does human food and supplements. It is crucial to choose a product that has undergone independent testing to guarantee its quality and purity. Also, you may determine whether the fish oil you’re thinking about has The NASC Quality Seal, since any company that bears it needs to adhere to extremely strict requirements.

Price

Vitamins for both humans and dogs may be rather expensive! Compare pricing, ingredients, and quality carefully since you could discover many products with the same components, etc., at drastically different prices.

Buy Pets Supplies on Amazon

Reviews

You may get the real truth about a product’s quality and advantages by reading reviews from other pet owners who have tried it. But bear in mind that every dog reacts to diets and supplements differently, so even the best-reviewed item may not be right for your dog.

Conclusion

Because of its certification from the National Animal Supplement Council and additional vitamins and antioxidants, Grizzly Omega Health Omega-3 is our recommendation when looking for the finest overall fish oil for your dog. We suggest American Journey Wild Alaskan Salmon Oil Formula as the finest fish oil for the money since it is affordable and yet includes 51% salmon oil.
