Welactin® Omega-3 is a fatty acid supplement given to large and small animals, including dogs, cats, and horses. This over-the-counter supplement is used alongside other medications to help manage a range of ailments, including inflammation, constipation, heart disease, and even cancer. The fatty acids in omega-3 supplements also improve the condition of a dog's coat.

Omega-3 fatty acids don't naturally occur in the body and are part of a balanced diet for dogs. Omega-3s are polyunsaturated fats primarily derived from fish oil. They're also present in flaxseed oil, hemp oil, primrose oil, and others. 

Specifically, omega-3 contains eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). Common health benefits of these polyunsaturated fats include regulating blood flow, reducing inflammation, and boosting immunity.

Before giving your dog any supplements, including Welactin® Omega-3, you should tell your vet as the supplements may interact with other medications. Welactin® Omega-3 comes in two forms: liquid and soft gel tablets. 

The recommended dosage for Welactin® Omega-3 depends on which form you've purchased. A bottle of liquid form Welactin® Omega-3 comes with a scoop used to measure the dosage. For dogs under 9 pounds, administer half a scoop every other day. If your dog weighs between 10 to 19 pounds, give your dog half a scoop every day. 

These measurements increase by half a scoop for 20 to 25 pounds of additional body weight. For example, dogs that weigh between 20 and 45 pounds should take a scoop and a half every day and so forth. You should administer liquid Welactin® Omega-3 by pouring it over your dog's food. 

If you are giving your dog omega-3 tablets, give your dog one tablet for every 20 pounds of body weight. Follow the directions on the bottle carefully and consult with your vet about dosages if you are unsure. 


Welactin® Omega-3 and other omega-3 supplements are often recommended by vets to help manage chronic conditions. As omega-3 fatty acids contain no additional drugs, they are safe to give dogs long-term. Side effects are very rare.
