Best Dog Fish Oil Supplements of 2025

"I've been adding this to my dogs' food for close to a year. I have a German Shepherd and an Australian shepherd, and both dogs now have shiny, healthy fur. I recommend this product to anyone who wants their pets to have softer, healthier fur."

"I recently started giving my dog fish oil as a supplement, and I'm thrilled with the results! This product has become essential to his daily routine. I've noticed a shinier and softer coat within weeks, and it seems to support his joints and digestion well. Easy to mix into food!"

"My doggy absolutely loves it! Her coat looks better than ever, and she enjoys the taste! While she’s still a bit itchy, she scratches much less frequently. I'll definitely keep buying this!"

"For years, I used other fish oil products, but after adding another dog to the family, a friend recommended this one. We’re never switching back! My dog is sensitive to smells, but there have been no issues. The pump bottle is easy to use and stays mess-free. Both dogs have shown significant improvements in their coat health, looking shinier and softer. It's been an extremely effective and cost-efficient choice for us!"

"I buy this fish oil for my dogs and love that the bottle never leaks. As someone who is disabled, I really appreciate the pump feature. It's so easy to add to their food! My shepherd's coat has become much easier to brush, and my chihuahua is the softest my vet has ever seen. Their coats look fantastic!"

"I had to share my experience because this product has changed everything for my dogs. Since we started using this fish oil, their coats are incredible—shiny, soft, and healthy! Ezra, who has skin allergies, has seen major improvements. They love the taste and finish their food quickly. Plus, the price is so reasonable compared to other brands. We’re committed customers now!"

"I have been giving these to my dogs for years, and their coats are shiny and these contribute to my dogs' overall health. I ordered them 41 times over the years. This last order was interesting as the gel capsules had totally melted into each other, but Amazon's customer service was awesome and a replacement is on the way. Thank you, Amazon, and thank you Nordic Naturals for making a great product."

"I got these for my dachshund mix because their backs are prone to problems. After landing too hard and throwing out his back, I decided to give him these to support his joints. Within a week, I noticed a difference. I use a pin to poke a hole in it, so he can smell the fish, and he eats it like a treat without any tricks."

"Since starting this on our three shelties, their coats have turned glossy, silky, and wonderful. They get one daily and it’s excellent for their health too!"

"I’m so impressed with BARK&SPARK Omega 3 for Dogs! My dog has always struggled with shedding and skin allergies, but after just a few weeks of using these 180 fish oil treats, I’ve noticed a significant improvement. Her coat is shinier and softer, and shedding has reduced noticeably. She even seems to be less itchy, which makes her much more comfortable. The treats are easy to give, and she loves the taste, so it’s a win-win! I highly recommend this product for any dog owner looking to improve their pet’s skin and coat health. It’s truly been a game-changer for us!"

"I’ve been using this product for my black lab for 8 months, and it has been a game changer in his coat. It’s smooth and shiny visually and to the touch. My boy LOVES them. He gets 2 after breakfast and dinner. He has no stomach upsets, and his stools are good. Highly recommend."

"I was a skeptic when purchasing this product, but I needed to do something for my 3-year-old Sable Shepherd who was in discomfort, scratching, and shedding. We followed instructions and gave 6 chewables per day, and saw noticeable improvements in one week. I am about to order for the second time. Itching has reduced, and his coat has a healthy shine with less shedding. Excellent product! Have never written a review before, so perhaps that speaks for itself."

"I've been using the Wild Alaskan Salmon Oil for a few weeks, and the results are fantastic! My dog's coat is shinier and softer, and she's scratching much less. She loves the taste too—I just pump it onto her food, and she devours it."

"I normally have to give my cat steroids in winter for skin issues, but this oil has kept her skin hydrated and fur soft. She enjoys the taste and doesn't avoid it. It's high quality and doesn't upset her stomach."

"Once a year, I write a review on Amazon, and this Salmon Oil deserves it! It's affordable and lasts me a long time with my two large dogs. After just two weeks, I noticed a huge improvement in my dog's fur—it's glossy and she stopped scratching! I'm really satisfied with this product."

"I highly recommend this fish oil for my aging pointer. Her coat is much shinier and healthier, not to mention softer! This fish oil has also alleviated her joint pain, which is such a relief."

"I give one to my dog every morning, and he thinks it's a treat. Within a week, his itching has decreased significantly, which is impressive since he spends a lot of time outdoors. Absolutely recommend this as a treat!"

"I have a Boston Terrier with skin allergies, and I've been using this product for years. His coat is shiny, shedding is minimal, and his allergies are much better managed now. I appreciate the veterinary recommended dose of Omega 3's included!"

"I have four dogs, and they all love these chews! I was mainly looking for an omega supplement for their coats, but I noticed that my 10-year-old German Shepherd has shown improvement in her dysplasia pain, allowing us to reduce her vet medication. Her coat is now shinier and she seems to have more energy and playfulness. I’m also pleased that three of my dogs with sensitive stomachs tolerate these well, which is a big plus!"

"After switching from the liquid version to these soft bites while on vacation, I found that they greatly reduced my rescue dog's scratching. Within a week, her dry skin improved significantly. I’m thrilled with this healthy product and highly recommend it based on my experience."

"My Jack Russell was dealing with dry and itchy skin, so I decided to try these chews. While I can't say they made a noticeable difference, my dogs absolutely love the flavor. The packaging is great, keeping everything fresh. I did learn that it's best to split the dosage to prevent any upset stomachs."

"I got this for my rescue pup's legs and hips. His legs seem less stiff in the mornings, and I think it's working well. Plus, his fur is so soft and shiny, and he's shedding so much less! I can't believe it! He gets dry eye occasionally, but that has stopped being a problem. Love these things!"

"I have a black lab named Bugz who had flaky skin. After trying these omega-3 supplements, along with a limited ingredient diet, the flaking and itchiness disappeared! I just give her two pills every morning, and she loves the liver flavor!"

"My 6-year-old Beagle has been developing dry skin and shedding since our move to a low-humidity area. After using Amazing Nutritionals Omega-3 Fish Oil for three weeks, her skin irritation calmed down and she mostly stopped shedding! Her coat looks clean and shiny, and I've received many compliments."

"I think this is a must for any cat or dog. It helps with their coat and provides essential nutrients. The pump is super easy; just a couple small squirts per meal. It does leak a few drips, but that’s not a huge issue for me. The packaging is super cute and easy to store. It has lasted my cats at least 2 months, which is great! Not too many ingredients – I definitely recommend!"

"I have a 13-year-old pup who’s been itching for years. After changing her diet and adding this supplement, she seems to be no longer itchy, which is a huge relief! She loves the taste, and I suggest adding it to her food gradually. It’s been a game changer for her!"

"My dogs absolutely love this oil! I have a 10-year-old pittie with a black coat and dandruff, and after using it for about a month, her coat is shining. I initially bought it for our other dog recovering from a stroke, and it was recommended by our vets. I’ve had no issues with the pump dispenser whatsoever!"

"I switched between several brands of fish oil, and this one is the best for my dog's coat health and overall value. Other brands are overpriced or poorly designed. This product has a great squirt bottle, and my dog's coat is now shiner and softer than ever!"

"I've been giving this to my 17-year-old cat after she had issues with her fur. After a couple of months, her hair finally grew back long and soft. I keep using it for her general health, and she's still happy to keep me company!"

"My kitten absolutely loves this salmon oil! It has made him finish his food in one go, and he even licks the plate clean. Though it's early days for coat results, I'm confident about its benefits. The packaging was secure and leak-proof, and I'm very pleased with my purchase!"
