One of the most common supplements that pet owners buy for their pets is fish oil. It’s good for your health in many ways, but only if it’s the right kind, made by a trusted brand, and taken in the right amount. Here you can find the best fish oil supplements for dogs. But we’ll also take a more in-depth look at the main components and benefits of fish oil for dogs.

Fatty acids called EPA and DHA are the main components of fish oil. Both EPA and DHA are long chains of carbon and hydrogen atoms linked together and end with a carboxyl group. Because the first double bond comes after the third carbon atom, these acids are called omega-3 fatty acids. 

In nature, EPA and DHA are linked to glycerol, which has a three-carbon backbone. The name for this group of molecules is triglyceride. Triglycerides are what fish oil is. What makes it so special now that you know the science behind it? How much can you give your dog? In this post, you’ll learn the answer to those questions and the risk. 

Healthy Skin and Fur

Fish oil is moisturizing, giving dry skin the moisture it needs to heal and get better. It helps reduce swelling and pain. It helps shedding too! Many skin problems in dogs cause inflammation and redness, which can be itchy and make the dog want to scratch more. 

Reducing inflammation helps stop the cycle of scratching and hurting the skin. Studies show that adding fish oil to a dog’s diet reduces symptoms of many skin conditions, like psoriasis. The EPA in fish oil will make a dog’s coat healthier and shinier. It helps keep a dog’s coat from getting too dry and stops the hair follicles from getting too hard. 

When omega-3s were given to dogs, their skin and fur got better. This was especially true for dogs with atopic dermatitis and other skin conditions. If you give your dog regular fish oil supplements and brush them every day or once a week, depending on the breed, their coat will look significantly better.

Brain and Eye Benefits

Since omega-3 fatty acids are part of the fundamental components of the brain, EPA and DHA are crucial for maintaining brain health. Fish oil is good for adult and older dogs because it helps keep them from getting depressed, anxious, or having trouble thinking. 

Fish oil has also been shown to help humans and dogs remember things, learn better, and act better. Just like human babies, puppies may also benefit from fish oil, which allows the brain to develop normally, especially if given to pregnant mothers. 

DHA is good for the brain, but it is also good for their eyesight. DHA can help puppies’ eyes develop well. Studies have shown that DHA can help adults with glaucoma, dry eye syndrome, and macular degeneration keep their eyes from getting worse or slow down the process.

Heart and Immune System

The effectiveness of fish oil for dogs in lowering blood pressure and lipid levels is among its most well-known advantages. High triglycerides are typically not a problem for dogs, although high blood pressure can be. For instance, a drop in blood pressure can help some dogs with heart disease whose hearts have trouble pumping blood. 

Prescription drugs are often used to lower a dog’s blood pressure, but fish oil supplements can also be helpful. Frequent fish oil supplementation of omega-3s can reduce the need for pharmaceuticals, which have various potential adverse effects. 

According to recent studies, the DHA in fish oil can boost B cell function. White blood (B) cells are crucial to the immune response of the dog’s body. Specialized immune cells called B cells produce antibodies. Antibodies adhere to the antigens on pathogens. This inhibits germs and marks them as intruders that need to be removed.

Diabetes and Kidney Disease 

In recent trials, supplemental fish oil has been found to lower the risk of type 2 diabetes. This occurs because of rising levels of the hormone adiponectin, which affects insulin sensitivity. The same benefits of fish oil supplements apply to canines with type 2 diabetes. 

Some dog owners have even discovered that their pups can go without medicine altogether with a healthy diet and fish oil supplements. High doses of fish oil have been proven to slow kidney disease and renal failure in dogs, according to researchers looking into its usage in kidney failure patients. 

Even more proof for this was revealed in other human investigations. In one study, 85% of renal failure patients still had functioning kidneys eight years after starting large doses of fish oil. In contrast, 56% of patients did not consume fish oil.

Fish Oil Types and Dosages

Finding the ideal fish oil dosage for dogs is not something that can be done in a rigid, straightforward manner. Different dosages are required to help with other health issues. 

You must consult your veterinarian to determine the proper dosage of fish oil for your dog. To establish how much fish oil you should provide for your dog, they’ll consider your dog’s age, weight, health, and current diet. 

If you give your dog a fish oil supplement made for dogs, follow the dosage instructions on the package unless your vet tells you otherwise. Fish oil comes in three types: 

Liquid: For households with multiple pets, liquids work best. Pets can easily get various dosages based on their needs, and you can add them to food to make them more convenient to administer.

Chew: If your pet dislikes taking pills, chews are a terrific way to give them their daily fish oil.

Pill: People often take fish oil in capsules, so they don’t have to deal with the fishy taste, but dogs tend to like the taste of fish oil. If you prefer this style, you can hide the pill in treats or use a special tool to give it to your dog. 

Risk

Pets with sensitivity to fish oil shouldn’t consume it. Utilize trustworthy sources of fish oil; heavy metal toxicity can happen if you use unreliable ones. Pets receiving anticoagulant drugs or who have blood-clotting issues should use fish oil with caution because it can intensify the anticlotting effects. 

It should be administered with caution in dogs that have diabetes or a history of pancreatitis. If your dog has any medical problems, consult a veterinarian to ensure that taking fish oil is safe for them. 

Before giving fish oil to nursing or pregnant pets, you should first consult a vet for permission. Because there is a possibility of vitamin A overdose, high doses should be taken with caution. Fish oils are often safe but can have side effects in large doses, such as: 

  • diarrhea 
  • vomiting 
  • slow wound healing 
  • tiredness or weakness
  • a fishy odor coming from the dog’s breath or skin
  • itchiness
  • oily coat 
  • flaky skin

If you stop giving them fish oil, the side issues should resolve. The severe side effects include: 

  • recurring upset stomach 
  • pancreatitis
  • abnormal bleeding or bruising
  • heavy metal toxicity  
  • incoordination
  • seizures

Conclusion 

Fish oil can offer several benefits to your dog, like boosting their immune system, helping eye and brain health, and relieving joint pain. It can help with skin and fur health, which is great for dogs who shed or have dry skin. 

Different types of fish oil supplements are available, and it’s essential to pick a great one for your dog as this will offer the most benefits. If your dog has medical conditions, it’s always best to talk to your vet about what fish oil dosage is best for your dog. 

So check out a few options and see if fish oil is right for your pup! They are sure to appreciate your advocating for their health and taking the initiative to make them as healthy as possible.
