Arthritis Is Far More Common Than Most Owners Realise
Studies suggest that as many as one in five adult dogs is affected by osteoarthritis. Among dogs over seven years of age, that proportion rises sharply. Despite this prevalence, arthritis is frequently underdiagnosed because dogs are highly effective at masking pain. By the time an owner notices obvious limping or reluctance to move, the condition is often already well advanced.
What Is Happening Inside the Joint
Osteoarthritis involves the gradual deterioration of cartilage, the smooth tissue that cushions the ends of bones within a joint. As cartilage breaks down, bones begin to contact each other more directly. The body responds by producing bone spurs and increasing joint fluid, which causes swelling, stiffness and pain. The joint becomes a site of chronic, low-grade inflammation that worsens with time and is not reversible.
Recognising the Subtle Signs
Because dogs rarely vocalise pain from chronic conditions, owners need to watch for behavioural changes rather than waiting for obvious symptoms.
- Slowness to rise after rest, particularly in the morning
- Reluctance to climb stairs, jump into the car or get onto furniture previously used freely
- Reduced enthusiasm for walks or shorter self-imposed distances
- Irritability when touched around certain areas of the body
- Licking or chewing at specific joints
- A change in gait, even subtle, such as favouring one side
Pain is not always dramatic in dogs. A dog that has stopped doing something it used to enjoy is telling you something significant.
Factors That Influence Progression
Body weight is one of the most powerful variables in arthritis management. Every kilogram of excess weight places additional load on affected joints. Even a modest reduction in body weight in overweight dogs produces measurable improvements in mobility and comfort. This is one of the few interventions that is entirely within an owner's control.
Exercise also plays a role, though the type matters. Short, frequent walks on even terrain are generally better than infrequent long walks with variable terrain. Hydrotherapy has strong veterinary support for maintaining muscle mass and joint mobility without the concussive impact of land-based exercise.
The Role of the Sleeping Environment
During rest, arthritic dogs need adequate cushioning to protect painful joints from pressure and a surface that is warm enough to prevent stiffness. Getting up from the floor is often the hardest moment of the day for an arthritic dog. A bed that is the right height and firmness can meaningfully reduce this struggle and the associated pain.
Working With Your Vet
Arthritis management is a long-term, multifaceted process. Veterinary input is essential for pain assessment and medication where appropriate. Owners who monitor their dog's mobility closely and communicate changes to their vet are far better positioned to adjust management strategies before significant deterioration occurs.
