The rising prevalence of osteoarthritis (OA) in companion animals-particularly dogs, cats, and horses-is significantly driving the global companion animal osteoarthritis market. In canines alone, estimates suggest that approximately 20% of dogs over one year of age show clinical signs of OA, and this prevalence can escalate to as high as 80% in older dogs, according to both clinical observations and radiographic studies. Similar trends are observed in felines, where OA is often underdiagnosed but increasingly recognized in aging cat populations, with some studies indicating radiographic signs in up to 90% of cats over 12 years old. Equine OA also remains a leading cause of reduced performance and early retirement, especially in sport and racehorses.
Several factors are contributing to this increase in OA prevalence, including extended pet lifespans due to advances in nutrition and veterinary care, rising rates of obesity (a major OA risk factor), and improved awareness and diagnostic capabilities among veterinarians and pet owners. These trends are expanding the demand for early diagnosis, chronic disease management, and pain relief solutions.
This growing burden has catalyzed significant investment and innovation in OA therapeutics, including the development of novel biologics, regenerative therapies (e.g., stem cells and PRP), monoclonal antibodies (such as Zoetis’ Librela and Solensia), and other multimodal pain management approaches. Pharmaceutical and biotech companies are actively developing long-acting, targeted therapies that offer better compliance and improved quality of life for pets, particularly as pet owners increasingly seek premium and preventative care. In parallel, the surge in veterinary visits and emphasis on mobility monitoring and wellness programs is reinforcing a robust market for diagnostics, supplements, joint-support diets, and rehabilitation services.
Altogether, these epidemiological and behavioral factors are not only expanding the companion animal OA patient pool but are also transforming the disease into a cornerstone segment of the global animal health industry-creating long-term growth opportunities across therapeutics, diagnostics, and supportive care solutions.
Despite strong market performance and widespread adoption of OA-targeting monoclonal antibodies like Librela, the recent public controversy-including calls for outright bans and new data suggesting a nine‑fold increase in musculoskeletal adverse events-poses a reputational and regulatory challenge. Heightened scrutiny from regulators like the FDA and EMA may result in tougher post‑market surveillance, label revisions, or prescribing restrictions. In the short term, veterinarians and pet owners might pivot toward more conservative options, such as established NSAIDs or supplements, potentially slowing growth in the biologics segment. However, transparent safety studies, improved pharmacovigilance, and clear risk-benefit guidelines could restore confidence and ultimately solidify the position of mAb therapies as a premium OA treatment-assuming manufacturers respond proactively
