Everything You Need to Know about Osteoarthritis in Dogs

Osteoarthritis in dogs is a long-term, degenerative joint disease in which the cartilage that cushions the joints wears down, causing pain, stiffness and less movement. It's most common in older, large-breed and overweight dogs, and in dogs with past joint problems like hip dysplasia or a torn cruciate ligament. There's no cure, but a vet-guided plan built on weight control, the right exercise, pain management and joint support can keep most dogs comfortable and active for years.

Osteoarthritis in dogs is a common problem. A 2015 review and the American College of Veterinary Surgeons both describe it as affecting roughly one in four dogs.

Osteoarthritis involves inflammation and breakdown of the synovial joints. This degenerative joint disease is a common chronic problem in senior dogs, particularly in large breeds. Its development is affected by age and weight. The key is to identify the problem early on and start care to improve quality of life and keep the dog active.

What Is Osteoarthritis in Dogs?

The cartilage acts as a cushion to move the joints freely through their full range of motion. However, they degenerate over time, leading to loss of movement and pain. Age, injury, disease, or repetitive trauma could cause the cushion to break. The cartilage thinning, fluid build-up, and bony outgrowths around the joints worsen joint inflammation and decrease the range of motion. Other possible causes of joint degeneration include developmental malformation, infection, trauma, or immune-mediated abnormalities.

A quick note on food: for a dog with sore joints, the goal is high protein with fewer calories, and a reduced-fat recipe makes that easy.

Osteoarthritis can develop in any joint of the body but is mostly seen in the lower spine and limbs. It could be classified as primary or secondary. Primary osteoarthritis is usually associated with aging or those which are of unknown cause (idiopathic). Secondary osteoarthritis occurs because of another joint problem, such as dysplasia (hip/elbow), cruciate ligament tear, patellar luxation, or other injuries. Regardless of its classification, the series of changes as the disease progresses degrades joint health.

What Are the Risk Factors of Osteoarthritis in Dogs?

Age and weight are the most important factors, with middle-aged to senior dogs being most at risk. Obesity as a result of diet or improper nutrition is one of the most common factors.

Another contributing factor is a lifestyle, including exercise and repetitive stress from athletic activities.

Genetics is also said to play a part, having a predilection to large or giant breeds such as Labrador Retrievers, Golden Retrievers, German Shepherds, Rottweilers and Mastiffs. Breeds prone to hip and elbow dysplasia or cruciate ligament tears, including many bully breeds and Cane Corsos, are also at higher risk of secondary osteoarthritis.

Other risk factors include infections and injuries of the joints, such as Lyme Disease or dysplasia and ligament tears.

Symptoms are not apparent until the joint is badly damaged, which is why osteoarthritis is hard to detect in its early stages. As part of their natural instincts in the wild, some dogs are good at hiding pain until they can no longer hold it, but by then, the case is already severe. It is crucial to stay up-to-date with regular veterinary visits if your dog is predisposed to developing osteoarthritis. They can help monitor your dog’s weight, and lifestyle, notice early signs, and address the condition before it becomes serious.

Since weight is one of the biggest risk factors, keeping your dog lean is one of the simplest things you can do for their joints. A lower-fat food lets you keep meals satisfying with fewer calories in the bowl.

What Are the Signs of Osteoarthritis in Dogs?

Early signs are easy to miss and often get blamed on "just getting older." Watch for:

• Stiffness when getting up, especially after rest or in cold weather
• Reluctance to jump into the car or onto furniture, or to use stairs
• Lagging behind on walks or wanting to turn back early
• Limping or favoring a leg, which may come and go
• A change in posture or gait, such as a swaying or bunny-hopping back end
• Muscle loss over the hips or back legs
• Licking or chewing at a joint
• Irritability when touched in certain spots, or less interest in play
• Swollen joints, or a grating sound or feeling when a joint moves in advanced cases

Pet parents may also notice general signs like lethargy and lower energy. If you notice any of these, book a vet visit. Starting care early makes a real difference.

How Do Vets Diagnose Osteoarthritis in Dogs?

It is important that you bring your dog to a vet if you suspect that they are suffering from or have observed some signs of osteoarthritis. The veterinarian would start by conducting a physical examination. This would include palpation of the joints and assessing the range of motion. Swollen and relatively warm joints indicate inflammation. The presence of thickening, muscle atrophy and crepitus will also be checked. To further evaluate the condition and see the extent of damages, if there is any, the veterinarian may also order radiographs (x-rays). In some cases, more advanced imaging techniques may be done, such as CT and MRI. Samples may also be taken for joint fluid analysis and bloodworks. Arthroscopy may also be performed, wherein a small incision is done to evaluate the joint structures using an endoscope.

Is There a Treatment for Osteoarthritis in Dogs?

Managing osteoarthritis could be through surgical or medical intervention.

Surgical options could be a preventive, repair, or salvage procedure. The purpose of preventive procedures is to improve the function and structure of the joint and delay the onset of arthritis, allowing the joint to function more normally. This is usually applied in cases of ruptured ligaments, patellar luxation, elbow and hip dysplasia, limb deformities, fractures, and joint dislocations. Once arthritis has already occurred, repair surgery such as joint replacement is an option to reduce pain and improve the function of the affected limb. However, if the arthritis is beyond repair, salvage surgery such as arthrodesis and Femoral Head and Neck Excision (FHNE) are performed to make the patient comfortable and mobile again. This is usually a last resort because the joint can no longer function normally.

Medical intervention may include the use of drugs, weight loss, warm compress, exercises, physical therapy or a multimodal approach to ensure joint health. Medications to address inflammation, pain, and to slow down the disease progression are usually prescribed. These would include corticosteroids, NSAIDS, Adequan, gabapentin, tramadol, and amantidine. Your vet will choose and dose these based on your dog's health, since some are used with caution in dogs with liver or kidney disease. Never give your dog human pain relievers such as ibuprofen, naproxen or acetaminophen. They can be toxic to dogs. Supplements such as glucosamine, chondroitin, omega 3 fatty acids, glycosaminoglycans, antioxidants, and other joint-support products are often used long-term alongside your vet's plan.

Alternative therapies such as acupuncture, cold laser, physiotherapy, physical therapy, chiropractic manipulation, swimming and underwater treadmill are also utilized for the management of osteoarthritis .

Weight management is important to all dogs, with or without osteoarthritis. The excess weight exacerbates osteoarthritis as it inflicts pain and speeds up cartilage breakdown. Keeping your dog at a healthy weight from puppyhood is one of the best ways to lower the risk. If at some point, being overweight is a risk factor, your veterinarian might prescribe a therapeutic weight loss diet. Some of these formulas also contain joint-support ingredients. For everyday support, Bully Max 9-in-1 Vitality Chews include joint support along with gut, immune, skin and coat support.

Can You Prevent Osteoarthritis in Dogs?

You can't always prevent it, especially in dogs with genetic joint problems, but you can lower the risk and slow it down:

• Keep your dog at a healthy weight for life, starting in puppyhood.
• Feed large-breed puppies a food made for growth and avoid overfeeding. See our guide to the best pitbull puppy food.
• Hold off on high-impact training, like repeated jumping or weight pulling, until your vet confirms your dog's growth plates have closed.
• Build fitness gradually and warm up before hard exercise. Our guide to how much exercise dogs need can help.
• Get injuries and limping checked early, since untreated joint injuries often lead to arthritis.
