Does omega-3 algal oil improve osteoarthritis in dogs?

[UK] Owners of dogs showing signs of osteoarthritis are being asked by the University of Bristol’s School of Veterinary Sciences to take part in the first study of its kind to find out whether an omega-3 oil derived from algae can help dogs with osteoarthritis (OA).

The double blind placebo-controlled trial, funded by the Dogs Trust, is led by Dr Jo Murrell and a team of animal health and welfare specialists in the Vet School.

The aim of the study is to investigate whether docosahexaenoic acid (DHA) reduces pain and improves quality of life in dogs with OA. Dogs will be randomly allocated to either the treatment or placebo group and will be given capsules on a daily basis throughout the study.

DHA is an omega-3 fatty acid found in fish oil and in higher levels in algae. Fish oil supplementation can have a beneficial effect on some aspects of OA in dogs and recent research has shown that DHA may have specific anti-inflammatory effects when given in higher quantities than are present in fish oil. There are no known side effects associated with DHA. What your dog eats is important for their overall health in many ways, for example they benefit from the nutrients in fruit just like humans do. You might be thinking ‘Can dogs eat fruit‘? because of the high sugar content, and the answer is that only certain fruits are safe, such as apples and apricots.

OA, also known as degenerative joint disease, is the most common type of arthritis seen in dogs and is a very common cause of chronic pain, particularly in older dogs. OA is often a point of discussion for dog owners. Sharing their advice on how they support their dogs helps owners support their canines through this awful, common disease. OA is sometimes featured in dog guides similar to, highlighting how common of an issue this can be if reputable dog guides are providing information on how to treat or prevent it. They do this because it’s hard to spot if you don’t know the telltale signs. OA is a slowly progressing disease where the cartilage in the dog’s joints breaks down and causes friction between the bones resulting in outgrowths of new bone forming, known as osteophytes.

Signs of OA include difficulty jumping up, stiffness after walks, difficulty walking up stairs, and reduced willingness to exercise or play, and the study team would be keen to hear from the owners of dogs experiencing these problems.

Owners will be asked to bring their dog to the Vet School for five separate visits over a four-month period and at each appointment complete questionnaires to assess the dog’s pain, stiffness and quality of life. The dog’s bodyweight distribution will also be measured at each appointment using a pressure sensitive plate.

Megan Goff, Research Technician in Companion Animal Studies, said: “”By taking part in the study your dog can help us understand the role this specific omega-3 plays in alleviating pain associated with osteoarthritis. The knowledge we gain from this research will make a contribution towards improving potential treatments available for osteoarthritis and improve the lifelong welfare of the many dogs worldwide affected by osteoarthritis.”

Some pet owners are already giving their dogs unprescribed medication to help alleivate the pain their dogs are feeling with products like CBD tinctures and treats available on and other websites. Others may not be as aware of the symptoms and warning signs, and may not be medicating their pets at all.

Members of the public who own a dog of any age or breed weighing over 12kg that is showing signs of osteoarthritis of the hind limbs and who are not receiving regular medication, are invited to take part in the project by emailing [email protected] or telephoning 07510 993922.
