Dr Ewen Blaikie, local veterinarian and small animal orthopaedic surgeon, recently spoke about the challenges arthritis poses for pets and what owners should watch out for.

Signs Your Pet Might Have Arthritis

Arthritis does not always announce itself with obvious symptoms like limping or stiffness. Sometimes changes are subtle:

  • Pets might show small changes in movement or behaviour, such as reluctance to jump, difficulty climbing stairs, or appearing stiff after resting.
  • Limping or stiffness can be signs, but these aren’t always obvious.
  • Cats often show arthritis differently than dogs, tending to hide discomfort and showing less obvious symptoms, like reduced grooming or quieter behaviour.

Causes of Arthritis

Osteoarthritis, the most common form, occurs when joint cartilage gradually wears down. Certain conditions increase the risk:

  • Cruciate ligament disease, hip dysplasia, or elbow dysplasia can lead to arthritis later in life due to joint instability or wear.
  • Osteochondritis dissecans (OCD), a joint developmental disorder, may also increase arthritis risk.
  • Some breeds are genetically predisposed to arthritis, so knowing your pet’s breed risk can help with early monitoring.

How Arthritis Progresses

Arthritis worsens over time as the joint’s cartilage erodes, leading to inflammation, swelling, and pain.

  • Pain often develops gradually but can flare up suddenly.
  • Untreated arthritis can lead to chronic pain, decreased mobility, and muscle loss.

Treatment and Management Options

While arthritis cannot be cured, various treatments help ease symptoms and improve mobility:

  • Medications: Non-steroidal anti-inflammatory drugs (NSAIDs) reduce pain and inflammation, while disease-modifying drugs support joint health.
  • Supplements: Nutraceuticals like glucosamine, chondroitin, and omega-3 fatty acids can help protect joints and decrease inflammation.
  • Weight control: Maintaining a healthy weight reduces stress on affected joints.
  • Exercise: Gentle, low-impact activities such as swimming or controlled walking help keep muscles strong without overloading joints.
  • Surgery: In severe cases, surgery may be required to repair damaged joints or remove painful growths.
  • Physical therapy: Specialist rehab programs can improve mobility and decrease pain.

With early detection and ongoing management, pets with arthritis can continue to enjoy an active and happy life. Regular veterinary check-ups are essential to tailor treatments specific to your pet’s needs and ensure their comfort.
