Choosing Omega-3 for Dogs: What to Know Before You Buy
Omega-3 fatty acids are a popular addition to many dogs' diets, with owners seeking to support skin and coat health, reduce inflammation, and ease itching. A recent survey of dog owners and veterinary recommendations highlights a range of supplements, from liquid oils to softgel capsules and soft chews, each with distinct features in terms of potency, source, and ease of administration.
Among the liquid options, Chew + Heal Wild Alaskan Salmon Oil stands out for its single-ingredient formula, made exclusively from wild-caught Alaskan salmon. It provides EPA and DHA along with omega-6, vitamin D3, vitamin B12, potassium, and phosphorus. The pump dispenser allows for easy dosing: one pump (half a teaspoon) per 25 pounds of body weight, up to four pumps daily for dogs over 75 pounds. The product, made in the United States, requires refrigeration after opening and should be used within 90 days. Some users note a strong fishy odor, though many dogs seem to enjoy the taste.
For budget-conscious owners, Zesty Paws Wild Alaskan Salmon Oil offers a cost-effective option. Each teaspoon delivers 850 milligrams of omega-3s, including DHA and EPA. The squeezable container, similar to a sunscreen bottle, makes it easy to add to both dry and wet food. It contains no artificial flavors, preservatives, or synthetic colors, and is also safe for cats. Refrigeration is needed after opening.
Pet owners seeking maximum potency might consider PetHonesty Omega-3 Fish Oil Supplement. With 1,438 milligrams of omega-3s per two pumps, this liquid is sourced from sardines, mackerel, anchovies, and herring caught off the coast of Iceland. The brand uses third-party testing to verify purity, and the oil is processed to reduce fishy odor. However, the pump mechanism has been reported to break on occasion.
Nordic Naturals Omega-3 Liquid Supplement is another liquid choice, formulated from wild-caught fish from Icelandic waters. It is purified to remove 99 percent of the fishy taste and smell, and is produced in an FDA-certified facility with third-party testing. While pricier, it contains no artificial colors, flavors, or preservatives.
Balancing Omega-3 and Omega-6
Natural Dog Company Wild Alaskan Salmon Oil offers a balance of omega-3 and omega-6 fatty acids. Since most dogs get enough omega-6 from their regular food, this supplement aims to provide a ratio that avoids over-supplementation. Each half-teaspoon pump delivers about a quarter of a dog's daily omega-3 needs and only 3 percent of their omega-6 requirement. The liquid is shelf-stable, does not require refrigeration, and comes in 8, 16, or 32-ounce bottles.
For those who prefer capsules, Nutramax Welactin Omega-3 Skin and Coat Supplement provides 120 softgels, each containing 300 milligrams of omega-3s. The formula includes peppermint oil to mask fishy odor. The recommended dose is one capsule per 20 pounds of body weight, so larger dogs may need several daily. Nutri-Vet Fish Oil for Dogs also offers softgels, with 100 capsules per container and a dose of one per 30 to 60 pounds. These pills are mess-free and do not require refrigeration.
For multi-pet households, Grizzly Omega Health Liquid Omega-3 Supplement comes in a 64-ounce jar, offering savings through bulk purchase. Sourced from wild Alaskan salmon and pollock, it provides 1,090 milligrams of omega-3s per teaspoon. The pump top is convenient, though the oil has a strong smell and can get messy. It carries the National Animal Supplement Council quality seal and is safe for cats.
Soft chews are another option. Nutramax Welactin Omega-3 Supplement for Dogs Soft Chews contains EPA, DHA, and ETA, and is designed to support skin, coat, and immune health. Each bag has 60 chews, with a half-chew serving per 10 pounds of weight. The resealable bag keeps chews fresh, though the natural fish flavor may not appeal to picky eaters.
Plant-Based Alternative
For dogs with fish sensitivities or owners preferring a plant-based option, WagWell's Ahiflower Omega Oil offers an alternative. Made from the corn gromwell plant, this oil provides omega-3, 6, and 9 fatty acids, along with biotin. It is odorless and flavorless, and suitable for all ages and sizes. Recommended dosage is one pump for dogs up to 60 pounds, two pumps for larger dogs. Each serving contains 585 milligrams of omega-3s, but the exact DHA and EPA content is not listed. The product is made in the United States and is free of wheat, corn, and soy.
When choosing an omega-3 supplement, owners should consider factors such as the dog's weight, the form that is easiest to administer, and the product's sourcing and testing. Consulting a veterinarian before starting any new supplement is always advisable.
