What causes a dog to get arthritis?

Ever noticed your pup slowing down on walks? Maybe they hesitate to jump on the couch these days, or limp a little after napping. These small changes might not seem like much, but they could be early signs of something more—like arthritis. It’s a common issue, especially as our furry friends get older, but what really leads to those stiff joints?​

Age plays a big role, no doubt. Just like humans, a dog’s joints wear down over time. The cartilage that cushions bones gets thinner, making movement less smooth. But it’s not just about getting old. Some breeds are more prone from birth—think larger dogs like Labradors or German Shepherds, whose bodies carry more weight on their joints. Their genetics can set the stage for arthritis later, even if they’re active and healthy as puppies.​

Carrying extra weight doesn’t help either. A few extra pounds puts way more pressure on knees, hips, and elbows. It’s easy to overfeed those puppy eyes, but consistent overeating can speed up joint strain. Past injuries matter too—even a old sprain or broken bone that healed might leave joints weaker, making them more likely to develop arthritis down the line.​

Daily habits add up. Dogs stuck in small spaces without enough movement can have stiffer joints, just like humans who sit too much. On the flip side, intense exercise without warm-ups—like sudden sprints on hard pavement—can jar joints over time. And let’s not forget the weather; cold, damp conditions sometimes make existing joint issues worse, though they don’t cause arthritis on their own.​

Paying attention early makes a difference. Regular check-ups can catch signs before they get severe, and simple tweaks—like softer bedding, controlled playtime, and a diet that supports joint health—can ease strain. It’s also smart to stay mindful of local rules around dog care; keeping your dog at a healthy weight and ensuring they get appropriate exercise isn’t just good for them, it’s part of being a responsible owner.​

Your dog can’t tell you their joints hurt, but their actions speak volumes. Whether it’s a senior dog slowing down or a young pup with breed-specific risks, knowing what contributes to arthritis helps you keep them happy and mobile. After all, a pup who can chase a ball or climb the stairs is a pup living their best life.
