Fish oil for dogs has multiple health benefits, from improved joint health to itch-free skin. Read on to learn more if your pet could take advantage of this natural supplement – and which to choose for their unique needs.

There’s no secret that essential fatty acids, such as omega-3 and omega-6, are crucial for the healthy functioning of your pet’s body. These important nutrients help maintain healthy immunity, keep your dog’s skin and coat in top shape, promote optimal cognitive development and improve mobility, and that’s just the tip of the iceberg. But how do you get essential fatty acids to your pet? Fish oil for dogs is the most efficient way to include omega-3 in your pet’s diet- whether you’re preparing your pet’s meals on your own, or pouring crunchy kibble in their bowl, fish oil is easy to mix in with their food and most dogs don’t even mind the taste of it.

However, you shouldn’t just use any fish oil you come across first or just share your fish oil capsules with your pet. There are different concentrations and different formulations of fish oil out there, and it’s important to pick one that will suit your pet’s needs the best. A good choice for most dogs is fish oils that are made from wild-caught fish as farmed fish could contain potentially dangerous substances, those that are highly bioavailable (easier to absorb by your pet), and those that contain EPA and DHA in optimal levels. To help you make the right choice, we’ve handpicked the best fish oil for dogs that will have your pooch wagging their tail.

4. Best for Joints: Bonnie & Clyde Wild Omega 3 Fish Oil Supplement for Dogs

Senior dogs and large breed dogs are often affected by joint pain and stiffness, hip dysplasia, and even arthritis. To prevent or at least delay the onset of these symptoms, as well as help reduce them once they appear, you will need to introduce essential fatty acids into your pet’s diet. EPA and DHA have an anti-inflammatory effect, so they can help with pain and swelling, and they also promote cartilage production and reduce stiffness.

6. Best Softgels: Strawfield Pets Omega 3 Fish Oil for Dogs

No matter how well you blend in fish oil or what tricks you resort to, some dogs just won’t touch their food if they see something is added to it- so you have to outsmart them.

Benefits of Fish Oil for Dogs

Fish oil is prized because it is rich in essential fatty acids, or more precisely, omega-3s called EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid). These polyunsaturated fats can have a significant effect on your pet’s health, both to prevent and delay health issues as well as help reduce or resolve existing ones. Some of the known benefits of EPA and DHA in fish oil include:

How Much Fish Oil Should I Give My Dog?

Once you figure out which fish oil works best for your dog’s needs, you’ll need to pay attention to dosage to ensure that they are getting the nutrients you need. You shouldn’t overdo it, because, for all its benefits and healthiness, fish oil for dogs has some downsides, too. Symptoms such as oily skin, fishy odor of the skin and coat, increased weight, vomiting, diarrhea, slowed healing, and more can all be attributed to fish oil overdose in dogs.

For therapeutic uses, experts recommend giving your dog anywhere between 50 to 220 mg of EPA and DHA per kilogram of their body weight. The highest dose is reserved for dogs with serious issues such as osteoarthritis, whereas milder problems need lower doses. However, doing the math on EPA and DHA dosage per serving (as they are just active ingredients in fish oil and not fish oil itself) and then adapting that to the needs of your pet can be difficult, so it’s best to consult with your veterinarian. Only a medical professional can give you the right advice on adding supplements to your pet’s routine and recommending the right dosage to treat their symptoms and maintain their overall health.
