Osteoarthritis in Dogs

What is arthritis in dogs?

Arthritis is the medical term for inflammation of the joints. Osteoarthritis (OA), in particular, is the most common form of arthritis in dogs. Most cases of osteoarthritis occur in dogs when the smooth cartilage that cushions the joints begins to wear down. As this protective layer thins, the bones may rub against each other, causing swelling, stiffness, and pain.

These early changes often show up in small ways: a dog who takes a little longer to stand, pauses before jumping onto the bed, or wants shorter walks than usual. It’s easy to assume these are normal signs of aging, but they can be early hints of arthritis. With timely care and a plan tailored by your vet, many dogs with OA can continue to enjoy the activities they love.

What are common signs of osteoarthritis in dogs?

Dogs may not yelp or cry when they’re hurting. Instead, they can show discomfort through changes in how they move or behave. These signs don’t confirm OA on their own, but they’re important to share with your vet.

Signs and symptoms of osteoarthritis include: 

• Slowing down on walks
• Being less playful
• Stiffness, especially in the morning or after naps
• Trouble getting up after resting
• Hesitating with stairs or jumping
• Taking longer to sit or lie down
• Limping or favoring one or more legs
• Popping or cracking sounds when the joint moves
• Acting sore when touched in certain areas (which can look like drawing back, discomfort on their face, or similar reactions)
• Licking their joints
• Whining, panting, or whimpering
• Loss of appetite
• Accidents in the house
• Depression or irritation

If something about your dog’s movement or mood feels “different,” trust that instinct. Pet parents are often the first to notice tiny changes. Osteoarthritis pain can often be missed, even when joint changes are present. This is one reason why early, small signs matter.

What causes osteoarthritis in dogs?

Osteoarthritis can range from mild to severe and has several possible causes. Any dog can develop the disease: young or old, large or small. Here are the most common causes and contributors:

• How a dog’s body is built: Some dogs have joint shapes or bone structures that put extra pressure on certain joints, increasing the chance of cartilage wear. Cartilage is the elastic, slippery tissue that covers the ends of bones and allows them to slide easily in joints.
• Large-breed size: Bigger dogs, including Labrador retrievers, golden retrievers, and German shepherds, may be more prone because their joints carry more weight throughout life.
• Extra weight: Overweight dogs put extra pressure on their joints with every step, which causes extra wear and tear on the joints.
• Joint issues early in life: Some dogs are born with joints that do not fit together quite right (dysplasia). This can make the joint wear down unevenly, starting when they are young.
• Past injuries: A past injury, like a torn ligament, a dislocated joint, or a broken bone near a joint, can lead to osteoarthritis later. It might show up months or even years after the injury.

Even when the exact cause isn’t clear, your veterinarian can help identify what’s affecting your dog’s comfort and guide you toward steps that support long-term joint health.

How do vets diagnose osteoarthritis in dogs?

Your vet will likely start by asking what you’ve noticed at home: changes in walking, jumping, playing, resting, or using the stairs. These details help guide the physical exam and testing plan. 

Diagnosis may include:

• Physical examination: Your veterinarian may gently move each joint to check for stiffness, swelling, or discomfort. Watching your dog walk or trot can also show changes in pace or how much weight your dog is putting on each leg.
• X-rays: These images show changes in and around the joints.
• Blood tests: Testing can help rule out infectious causes of joint inflammation, such as diseases spread by ticks.

With this information, your veterinarian may be able to diagnose osteoarthritis and build a plan that fits your dog’s needs.

How do veterinarians treat osteoarthritis?

Osteoarthritis is typically progressive, meaning it worsens over time. While there is no cure, many dogs feel much better with the right treatment plan. Your vet may recommend: 

• Pain relief medications, especially anti-inflammatories made for dogs. These help reduce joint inflammation and improve comfort. A blood test may be recommended before starting long-term anti-inflammatory medicine.
• Diet changes, especially if your dog needs to reach a healthier weight. Even small reductions in excess weight can significantly decrease stress on joints and improve mobility.
• Joint support supplements made to help maintain healthy cartilage and joint fluid.
• Low-impact exercise or simple physical therapy routines to help maintain muscle mass and joint stability.
• Surgery, especially for underlying issues like a torn ligament in the knee.

For some dogs, your vet may also talk about newer pain treatments for arthritis, like a monthly shot. They can help you weigh benefits and potential risks for your dog. 

If your dog is prescribed long-term medications, your veterinarian may recommend regular blood and urine tests to monitor liver and kidney health and check red blood cell levels. These tests can help detect subtle changes early and support safe, effective treatment.

Your dog’s plan may evolve over time, so regular checkups help fine-tune what’s working best.

How can you care for a dog with osteoarthritis at home?

Caring for a dog with osteoarthritis often begins with small adjustments to their everyday environment and routine. These simple changes can make a meaningful difference:

Start with small, supportive changes at home

• Soft, supportive bedding gives sore joints a comfortable place to rest.
• Rugs or nonslip mats help prevent slips and falls on smooth floors.
• Ramps or steps reduce the need for jumping into the car or onto furniture.

Keep movement gentle and consistent

Staying active still matters, but when a dog has osteoarthritis, steady, low‑impact movement is important.

Gentle, steady activity can help keep joints flexible:

• Choose short, regular walks rather than long or intense outings.
• Avoid rough play or high‑impact exercise unless your veterinarian recommends it.

Check in with your vet before starting or changing your dog's exercise routine.

Consider supportive, non‑drug therapies

Just like humans, dogs can benefit from physical therapy and non-drug therapies that support their comfort and mobility as part of their broader care plan, such as:

• Laser treatments
• Massage
• Hydrotherapy
• Acupuncture

These therapies are available through your local vet and/or veterinary professionals certified in canine rehabilitation therapy.

As you spend time together, note any changes in how your dog moves or behaves. Your observations help your vet adjust the care plan, so your dog stays as comfortable as possible.

How can you help prevent osteoarthritis in dogs?

While osteoarthritis can’t always be prevented, there’s a lot that you can do to help protect your dog’s joints. Here are a few simple habits to start building now:

• Maintain a healthy weight to reduce pressure on joints.
• Encourage regular, low-impact exercise.
• Schedule routine wellness checkups so your vet can detect early joint changes.
• Get any injuries treated by a vet promptly to help protect your dog’s joint structures.

These steps help support joint health through every stage of your dog’s life.

When should you see your vet?

Call your vet if your dog becomes stiff, sore, or unwilling to walk, climb, or jump. Sudden limping, crying out, or refusing to get up or put weight on a leg should be examined quickly.

If anything seems “off” or unusual about your dog’s joints, it’s always safest to reach out to your vet. Early evaluation allows for timely diagnosis and appropriate next steps to protect your dog’s health and mobility.

Final thoughts

Osteoarthritis often begins quietly, with small changes that are easy to write off as “just getting older.” But old age is not a disease. If you notice stiffness, hesitation, or a shift in your dog’s usual energy, those details matter. Sharing them early with your veterinarian can make a huge difference in your dog's comfort and mobility. With the right plan, many dogs stay active and happy for years. Paying attention to change and acting quickly helps your dog keep enjoying daily life, right by your side.
