The 10 Best Fish Oils for Dogs
1. Paws & Pals Alaskan Salmon Oil – Best Overall
If you’re looking for a nutrient-packed Fish oil supplement, Paws and Pals Wild Alaskan Salmon Oil is the best fish oil supplement for dogs to boost their overall health and wellness. Loaded fatty acids rich in Omega-3 with DHA and EPA, this fish oil supplement will help your dog’s immune system and brain function. It also contains Omega-6 fatty acids and biotin to help keep your pup’s skin and coat in prime condition. Paws & Pals Salmon Oil comes from sustainably caught wild Alaskan salmon and no artificial ingredients. This supplement is in liquid form, making it easy to add to your dog’s meals. The only issue is that some dogs do not enjoy the taste or smell. Other than some pickiness, this fish oil is a top of the line supplement to add to your dog’s diet.
2. Nutri-Vet Fish Oil – Best Value
Nutri-Vet Fish Oil liquid gel capsules are loaded with high-quality ingredients from natural sources. This fish oil is a great source of Omega-3 fatty acids as well as other important vitamins to help your dog’s normal shedding and boost skin wellness. Since they’re dosed by weight, these supplements can work for dogs of most sizes. The problem comes with the capsule itself since most dogs will not simply swallow a capsule. While it may not smell like liquid does, it may take more work to administer it to your dog. The capsule may also be too big for small dogs to swallow, which is why it comes in 2nd on this list. Otherwise, we find these to be the best fish oil for dogs for the money compared to other fish oil supplements.
Zesty Pawls Wild Alaskan Salmon Oil is a premium fish oil made with pure wild Alaskan salmon for multiple health benefits. Similar to #1 on this list, Zesty Paws salmon oil is a liquid that can be added to your dog’s food. The omega-3 rich fatty acids help support your dog’s immune system as well as a boost in heart and joint wellness. Taste preference will come down to what your dog likes (or dislikes), but most dogs enjoy the Zesty Paws. We recommend this oil if you’re looking for premium quality fish oil from naturally sourced wild Alaskan fish. We kept Zesty Paws out of our top two because it is on the expensive side compared to Paws & Pals and Nutri-Vet.
4. Vital Pet Life Salmon Oil
Vital Pet Life Salmon Oil is a liquid fish oil that can be easily added to your dog’s food. It’s made with real Alaskan salmon for a great source of fatty acids containing Omega-3 and Omega-6. The DHA and EPA from the Omega-3 will help boost coat health and help heal dry, itchy skin. If you’re new to fish oil supplements and you don’t want to spend a lot, Vital Pet Life Salmon Oil is a good option. The problem with this oil is the smell, which can be a bit strong. Some dogs may be too picky and refuse to eat it. Another potential problem is the richness of this oil, which may lead to indigestion. If your dog isn’t picky and you’re looking for pure salmon oil, Vital Pet Life Salmon Oil is a great choice.
5. Amazing Nutritionals Omega Fish Oil
Amazing Nutritionals Omega Fish Oil chew tablets are full of flavor and have no distinct “fishy” smell like liquids and soft-gel capsules. The chews contain all of the fatty acids and nutrients of fish oil in a convenient treat-sized chewable tablet with no artificial ingredients. While the chewable tablet is a less stinky option than liquid, these chews aren’t as nutrient-dense as other supplements. While the chews may taste better than the liquid, it’ll be more expensive for bigger dogs that require more than one chew a day. This may be your best option if your dog is really picky, but we recommend trying liquid or capsule supplements first.
6. TerraMax Liquid Omega-3 Fish Oil
The TerraMax Pro Liquid Fish Oil is a blend of fish sustainably sourced from the cold waters of Iceland. The pharmaceutical-grade fish oil blend is loaded with the essential fatty acids to boost your dog’s immune system and organ functions. The liquid form is convenient for feeding and administering, but this oil tends to have a strong fishy smell. Picky and stubborn dogs may not like the taste and refuse to eat it, wasting food and oil. The oil also may be too strong for sensitive stomachs, which can lead to digestive issues. If your dog has a sensitive stomach, pure salmon oil is a better option.
7. PetHonesty Salmon Oil
PetHonesty Salmon Oil is a chewable tablet supplement with a blend of salmon oil, Vitamin E and kelp packed into a flavorful treat. The salmon oil, fatty acids, and Vitamin E help keep your dog’s skin healthy and help reduce shedding. The kelp naturally boosts the immune system to help support normal thyroid function. Similar to other chews, the PetHonesty Salmon Oil chews may end up being more expensive if you have a larger dog due to dosage. There are other ingredients in the chews that may cause an upset stomach including grains and palm oil, so these chews may not be great if your dog has allergies or sensitivities. If your dog is smaller in size, the PetHonesty Salmon Oil chews are a good option.
8. Nordic Naturals Omega Fish Oil
The Nordic Naturals Omega Dog Fish Oil is a liquid capsule that contains a formulated blend of Nordic fish oils loaded with Omega-3 fatty acids. The fish oil itself is high quality, but the capsule contains a preservative that may upset your dog’s stomach. These capsules are also on the expensive side of the market compared to more nutrient-dense supplements. If there were additional nutrients for a better value, it would have been ranked higher on the list. Nordic Naturals Fish Oil capsules may be hard for smaller dogs to swallow and stubborn dogs may refuse to take them. On the plus side, the Nordic Naturals Omega Fish Oil capsules are almost completely odorless.
9. Fera Pet Organics Fish Oil
The Fera Pet Organics Fish Oil liquid supplement uses a blend Icelandic fish oil and Vitamin E that can be easily added to your pet’s meal. The fish oil blend is rich in Omega-3 fatty acids help keep skin and fur healthy while boosting your dog’s immune system. This fish oil contains no preservatives or artificial ingredients, which is great for dogs with allergies and sensitivities. The major problem lies in the strong scent, but it is marketed as an odorless supplement. Some dogs really did not like the flavor, so your dog may not like it if it’s picky. Fera Pet Fish Oil is also on the expensive side compared to the others on this list, but it doesn’t have the same quality and value as the other products on this list.
10. Harvey’s Health & Shine Omega 3 Fish Oil
Dr. Harvey’s Health & Shine Omega 3 Fish Oil liquid supplement contains a variety of wild-caught Nordic fish for natural sources of Omega-3 fatty acids for your pup’s health and wellness. The smell is not as strong as others, but it is not completely odorless. If your dog is picky, this may not be the best option, as some dogs do not like the taste. This brand would be okay if it weren’t so expensive to use with bigger dogs with an average of 4 to 5 pumps per dose. If you have a small dog that also isn’t picky, this fish oil may work. We recommend trying Paws & Pals Wild Salmon Oil for more nutrition and better value compared to Dr. Harvey’s Fish Oil supplement.
When shopping for fish oil for your dog, it’s important to check for top quality and naturally sourced fish oil rich in fatty acids and Omegas for a boost in your dog’s health. Omega-3 is especially important for dry skin and may help reduce shedding. You must also read labels to ensure the ingredients are 100% natural and sustainably sourced for your dog’s safety.
Another thing to consider is the type of supplement that is best for your dog. Most fish oil supplements come in liquid, capsule, or chewable form. Capsules that need to be swallowed may be difficult to administer to stubborn dogs. Liquid oil is usually considered the easiest method, but some picky dogs won’t eat it. Flavored chews are great for picky dogs but are more expensive and usually contain less nutrients than liquid supplements.
A good fish oil supplement will have both Omega-3 and Omega-6 fatty acids that are naturally sourced without being overpriced. The fish oil should be gentle on the stomach to avoid indigestion. While fish oil may have a “fishy” smell, a high-quality fish oil should not be overpowering.
Fish oil with additional nutrients like biotin for extra health benefits is also great for your dog’s health. Vitamin E is another nutrient added that helps aid digestion and absorption of fish oil. It’s also best to avoid fish oil with preservatives and artificial ingredients that are harsh on your dog’s stomach.
Before starting any supplements, it’s important to talk to your veterinarian about what options are best for your dog. While most dogs can safely consume fish oil, dogs with sensitive stomachs may suffer from indigestion after eating it.
After comparing tests and reviews of each product, we found that Paws & Pals PTWS-01-32 Wild Alaskan Salmon Oil is the best overall fish oil supplement. It is packed with the finest salmon oil rich in essential nutrients with your dog’s health in mind. We really liked the addition of biotin for a shinier, healthier coat. We also found Nutri-Vet 1001049 Fish Oil to be the best value. The liquid gel-caps are an odorless alternative to liquid fish oil and they’re more affordable than other fish oil supplements.
Hopefully, we have made shopping for high-quality fish oil supplements an easier task with the list we made of reviewed products. We looked for superior, naturally sourced ingredients and hope this guide will help you find the best supplements for your dog.
