TL;DR: Arthritis in dogs rarely starts with a limp. The early signs are stiffness after resting, slowing down on walks, hesitating at the car or sofa, and simply doing less than they used to. It is most common after age eight, but injury and hip or elbow dysplasia can bring it on much younger. Weight control, gentle daily movement, and vet-prescribed pain relief are the three things that change the picture most. Never give a dog human painkillers.
Osteoarthritis is one of the most common and most missed conditions in dogs. Estimates suggest around one in five adult dogs has some degree of it, and the majority of dogs over eight. The reason it slips past so many owners is simple: dogs do not complain. They just quietly do less, and we call it getting old.
What are the early signs of arthritis in dogs?
Watch for changes in how your dog moves, not for obvious pain. These are the clues that show up first:
- Stiffness after resting. The classic one. Your dog gets up creaky after a nap or first thing in the morning, then loosens up after a few minutes of walking.
- Slowing down on walks. They start out fine and lag on the way home, or the walk you both used to enjoy now needs to be shorter.
- Hesitating before jumping. A pause before hopping into the car, onto the sofa, or up the stairs. A dog that used to launch now thinks about it first.
- Reluctance on slippery floors. Laminate and tile become a problem because sore joints cannot brace against a slip.
- A changed sitting or sleeping position. Sitting with one leg kicked out to the side, or shifting position far more often at night.
- Licking one spot. Persistent licking over a wrist, elbow, hip, or knee often marks the joint that hurts.
- Muscle loss over the back end. Thinner thighs and a narrower rear are a sign your dog has been unloading a painful leg for months.
- Grumpiness when handled. A patient dog that suddenly objects to being brushed, lifted, or touched near the hips is telling you something.
- Less interest in play. Not joining in with other dogs, or giving up on games after two throws instead of twenty.
Any one of these on its own means little. Two or three together, building slowly over months, is the pattern worth a vet visit.
Which dogs are most at risk?
Age is the biggest factor, but not the only one. Excess weight matters enormously, because every extra kilo loads joints that are already sore and drives inflammation. Large and giant breeds carry more risk, especially Labradors, German Shepherds, Golden Retrievers, Rottweilers, and Bernese Mountain Dogs. So do dogs with hip or elbow dysplasia, and any dog that has torn a cruciate ligament, which very often leads to arthritis in that knee within a few years.
Small breeds are not exempt. Dachshunds, Yorkshire Terriers, and other small dogs get it too, and it is often missed for even longer because a small stiff dog is easier to carry past the problem.
How can you spot it before it shows?
The honest answer is that most owners cannot spot a 5 percent drop in daily movement by eye. It happens too gradually. What you notice is the day your dog will not get in the car, by which point the joint has been sore for a long time.
This is where tracking daily activity genuinely helps. A dog activity tracker like Rocket logs how much your dog actually moves each day, so a slow downward drift over a few weeks shows up as a line on a chart instead of a vague feeling that they seem tired lately. It is not a diagnosis, and it never replaces a vet exam, but an early, measurable change is exactly the prompt that gets a dog seen sooner. If you want a baseline to compare against, our guide to how many steps a dog should take a day sets out normal ranges by size.
What should you do if you suspect arthritis?
Book a vet appointment. Diagnosis is usually a hands-on exam checking each joint for pain and range of motion, sometimes with X-rays to confirm the extent. Bring specifics: when the stiffness is worst, what your dog now avoids, and how far they walk before flagging. A short phone video of your dog getting up after a nap is often more useful than anything you can describe in the room.
Then expect a plan built from several pieces rather than one fix:
- Weight first. Getting a dog to a lean body condition is the single most effective thing owners control. If your dog is carrying extra, our guide on how to tell if your dog is overweight shows how to check at home.
- Vet-prescribed pain relief. Dog-specific anti-inflammatories, and newer injectable options your vet can talk through. Never human painkillers.
- Controlled, regular exercise. Short walks more often, on soft ground, instead of one long hard outing. Swimming and lead walking suit sore joints far better than ball chasing. Our senior dog exercise guide covers how to structure this.
- Home changes. Rugs on slippery floors, a ramp into the car, a supportive bed, and food and water bowls raised to a comfortable height.
The bottom line
Arthritis is manageable, and dogs caught early do markedly better than dogs caught once they are limping. Trust the small stuff: the pause before the jump, the shorter walk, the leg kicked out to the side. If your dog is doing a little less every month, that is information, not just age.
