Osteoarthritis is one of the most common conditions seen in dogs across all breeds and ages, yet it remains chronically underdiagnosed — partly because owners may not recognise pain behaviours for what they are, and partly because the disease progresses so insidiously. By the time a dog is visibly struggling to rise, changes in cartilage, synovial fluid, and bone may already be well advanced. Grant Sheppard's thesis takes a clear-eyed look at where osteopathic manual therapy sits within the broader management of canine OA — not as a replacement for veterinary medicine, but as a clinically grounded complement to it. Beginning with a thorough review of the pathophysiology, from the initial breakdown of articular cartilage through to osteophyte formation and gait compensation, the paper builds the anatomical and biomechanical case for why manual intervention makes sense. The assessment framework described is rigorous: gait analysis, passive range of motion testing, postural observation, and end-feel evaluation all form part of the osteopathic encounter. A 'bone-to-bone' end feel, for instance, may indicate osteophyte development long before radiographic changes become obvious. This kind of nuanced clinical reasoning sits at the heart of the thesis. When it comes to treatment, techniques such as Osteopathic Articular Balancing, joint distraction, and soft tissue mobilisation are examined alongside the evidence for their effects — including improvements in synovial fluid production, reductions in inflammatory markers, and gains in passive range of motion. Owner-led home stretching protocols and adjuncts like hydrotherapy are also considered. The evidence base, Sheppard acknowledges, remains limited in scope and quality. But the trajectory is clear. For dogs whose owners are engaged and whose condition is managed across multiple modalities, osteopathy offers something conventional approaches often cannot: a non-invasive, drug-free means of addressing the whole animal.
