Summary: Human clinical studies and a recent meta-analysis7 have found that dietary supplementation with fish oil and fish oil-derived fatty acids (in particular omega-3 fatty acids) provides benefits for patients with rheumatoid arthritis. Although the pathophysiology of rheumatoid arthritis in humans differs from the pathophysiology of OA in dogs, both conditions have an inflammatory aspect that could be sensitive to omega-3 fatty acids. In 2 recent studies, the effects of dietary supplementation with fish oil omega-3 fatty acids in dogs with OA found that feeding a diet containing 3.4% to 3.5% omega-3 fatty acids improved some clinical outcomes and weight bearing. In clinical practice, many dogs with OA are treated long term with NSAIDs such as carprofen, and neither of the aforementioned studies9,10 examined whether dietary supplementation with omega-3 fatty acids would allow a decrease in NSAID dosage. The purpose of the study reported here, therefore, was to determine the effects of feeding a diet supplemented with fish oil omega-3 fatty acids on carprofen dosage in dogs with OA.
Conclusion: Results suggested that in dogs with chronic osteoarthritis receiving carprofen because of signs of pain, feeding a diet supplemented with fish oil omega-3 fatty acids may allow for a reduction in carprofen dosage.
