What Is Osteoarthritis?

Osteoarthritis (OA), also known as degenerative joint disease, is a progressive condition that leads to the breakdown of cartilage in the joints. As the cushioning deteriorates, pets experience pain, swelling, and reduced mobility. This condition is especially common in senior pets but can affect animals at any life stage.

In Santa Monica, where pets enjoy active lifestyles and long lifespans, osteoarthritis is a common concern among aging dogs and cats. National data suggests that at least one in four dogs will develop arthritis in their lifetime—making proactive care essential.

Recognizing the Signs

Cats and dogs may express joint discomfort in different ways. Some pets show visible signs, while others may exhibit subtle behavioral shifts.

Common Symptoms of Osteoarthritis

  • Limping or stiffness, especially after rest
  • Reluctance to jump, climb stairs, or play
  • Difficulty rising or lying down
  • Increased irritability or withdrawal
  • Overgrown nails from decreased activity
  • Changes in grooming habits (especially in cats)

If you’re seeing these signs, it may be more than just “slowing down.” This guide from AAHA outlines key pain indicators in pets.

Why Early Detection Matters

Osteoarthritis is easier to manage when caught early. Senior pets should receive wellness exams at least twice a year, even if they appear healthy. Preventive testing recommendations include bloodwork, urinalysis, and mobility evaluations to spot subtle changes.

Diagnosing Osteoarthritis

At Santa Monica Veterinary Group, our diagnostic process may include:

  • Orthopedic exams
  • Gait and range-of-motion assessments
  • X-rays to visualize joint changes or bone spurs
  • Advanced imaging (MRI or ultrasound) for soft tissue evaluation

We customize diagnostics based on your pet’s lifestyle, breed, and age. Visit our Services page to learn how we support early detection and mobility care.

Treatment Options

Medical Management

The most common first-line treatment for OA includes nonsteroidal anti-inflammatory drugs (NSAIDs) to control pain and inflammation. These are often combined with joint supplements and omega-3 fatty acids. See Purina’s guide to supplements for senior dogs.

Regular bloodwork is essential to monitor liver and kidney health when using long-term medications.

Integrative Therapies

Santa Monica Veterinary Group offers additional therapeutic options including:

  • Laser therapy to reduce pain and stimulate healing by enhancing circulation and cellular repair.
  • Physical rehabilitation to preserve mobility and strength through guided exercises, range-of-motion techniques, and strength conditioning.
  • Acupuncture, a key component of Traditional Chinese Veterinary Medicine (TCVM), which uses fine needles to stimulate specific points on the body. This promotes natural healing processes, improves energy flow (Qi), and can help manage chronic pain, arthritis, and even internal conditions like gastrointestinal or respiratory issues.
  • Assistive devices (e.g., harnesses, slings, ramps) to support daily movement and improve quality of life for pets with mobility challenges.

These integrative therapies are designed to work alongside traditional medicine, offering a well-rounded, personalized approach to your pet’s care. To learn more about our holistic services, visit our veterinary services page.

Nutrition & Weight Management

Excess weight places stress on joints. Our team can develop a customized weight loss or weight maintenance plan with therapeutic diets and calorie control.

Supporting Your Senior Pet at Home

Keep Them Moving—Gently

Regular low-impact activity helps keep joints lubricated and muscles strong. Short walks, swimming, and indoor play are great options. Avoid high-impact activities or rough terrain.

Considering Cognitive Changes

As pets age, arthritis can overlap with age-related cognitive decline (similar to dementia in humans). Signs include:

  • Disorientation
  • Changes in sleep-wake cycles
  • Vocalizing or pacing at night
  • Loss of housetraining

Frequently Asked Questions

How do I know if my pet’s slowing down is due to arthritis?
Changes like hesitation on stairs, limping, or decreased enthusiasm for walks can be signs. Some pets may become more withdrawn or irritable.

Can cats get arthritis too?
Yes, though they often hide their pain. Look for reduced grooming, avoiding jumping, or changes in litter box use.

Is osteoarthritis curable?
No, but it’s highly manageable. With the right care, many pets live full, active lives.
