Osteoarthritis or OA, sometimes referred to as “doggy arthritis,” is a chronic joint condition that affects many aging dogs—but it’s not just a problem for seniors. Though commonly diagnosed in dogs seven to eight years old, dogs as young as one may be affected, particularly if they have developmental joint issues. This degenerative disease causes the cartilage in joints to break down over time, leading to pain, inflammation, and decreased mobility.

What to Watch For

Is your once-playful pup moving a bit slower lately? Common signs of osteoarthritis include stiffness (especially after rest), limping, reluctance to jump or climb stairs, and a general decrease in activity. Some dogs may even show irritability due to ongoing discomfort.

What Causes Osteoarthritis in Dogs?

Osteoarthritis can result from everyday wear and tear, but several factors increase the risk. These include age, breed (larger dogs like Labradors and German Shepherds are more prone), previous joint injuries such as fractures or ligament damage, joint abnormalities like hip or elbow dysplasia, and obesity, which puts extra strain on the joints.

While there’s no cure, early diagnosis and proper management—through weight control, medications, supplements, or physical therapy—can greatly improve your dog’s quality of life. So, if your furry friend seems a little stiff, don’t chalk it up to “just getting old”—it could be osteoarthritis, and there are ways to help your dog feel better.

4. Reluctance to Move: Dogs may have trouble getting up or hesitate to do stairs.
