Osteoarthritis
Osteoarthritis (arthritis or degenerative joint disease) is one of the most common chronic conditions affecting older dogs and cats. It occurs when the smooth cartilage within a joint gradually wears down, leading to inflammation, discomfort, stiffness, and reduced mobility over time.
Arthritis can affect pets of any age, but it is more commonly seen in senior pets, overweight animals, large breed dogs, and pets with previous joint injuries or orthopaedic conditions. Because arthritis develops gradually, many pets show subtle signs that are often mistaken for “normal ageing.”
Signs of Arthritis in Pets
Pets with osteoarthritis may show:
- Stiffness, especially after rest
- Slowing down on walks
- Difficulty jumping, climbing stairs, or getting into the car
- Reluctance to play or exercise
- Limping or altered gait
- Trouble rising after lying down
- Muscle loss
- Behavioural changes such as irritability or withdrawal
- Sleeping more than usual
Cats are particularly good at hiding pain, so signs may be more subtle. Arthritic cats may stop jumping onto furniture, hesitate before jumping, sleep more, groom less, avoid stairs, or have litter tray accidents due to difficulty climbing into trays.
Diagnosing Osteoarthritis
Diagnosis is based on your pet’s history, clinical examination, mobility assessment, and sometimes X-rays. Our veterinarians will assess your pet’s joints, mobility, muscle condition, and overall comfort to help develop an individual treatment plan.
Early diagnosis and management can significantly improve quality of life and help pets remain comfortable and active for longer.

Managing Arthritis
While arthritis cannot be cured, there are many ways to successfully manage pain, improve mobility, and slow progression of the disease. Most pets benefit from a combination of treatments tailored to their individual needs.
Management options may include:
- Weight management
- Joint supplements
- Prescription arthritis medications
- Monthly arthritis injections
- Controlled exercise programs
- Physiotherapy and rehabilitation
- Home environment modifications
- Pain management plans
- Supportive bedding and non-slip flooring
Maintaining a healthy body weight is one of the most important ways to reduce stress on painful joints and improve mobility.
