Joints and mobility · Updated 2026-10-19
Canine osteoarthritis
A progressive, painful joint disease that can reduce mobility, sleep quality and willingness to exercise.

Signs to watch for
- Stiffness after rest
- Reluctance to jump or use stairs
- Shorter walks or lagging behind
- Licking painful joints
- Behaviour or sleep changes
Causes and risk factors
Cartilage breakdown and joint inflammation may follow age-related wear, developmental joint disease, previous injury, obesity or abnormal joint loading.
How veterinarians diagnose it
A veterinarian combines history, gait and joint examination with imaging where needed. Similar signs can come from spinal or neurological disease.
Treatment and management
Management is usually multimodal: weight control, tailored exercise, rehabilitation, environmental changes and veterinarian-prescribed pain relief. Supplements are not substitutes for proven analgesia.
Prevention
Keep dogs lean, build exercise gradually, avoid repetitive high-impact work in growing dogs and investigate persistent lameness early.
Outlook
It cannot usually be cured, but many dogs remain active and comfortable with ongoing monitoring and adjusted treatment.

Arthritic dog: what to change first
| Area | Practical step |
|---|---|
| Weight | Ask for a body-condition target and measured feeding plan. |
| Floors | Add non-slip runners and routes the dog actually uses. |
| Exercise | Regular moderate walks; avoid sudden intense sessions. |
| Furniture and car | Provide ramps or steps; stop repetitive jumping. |
| Pain relief | Only medication prescribed for this dog; never human products. |
Lameness and slowing have many causes. Sudden severe pain or inability to bear weight needs prompt veterinary care.
Stiffness is pain until a veterinarian says otherwise
Slowing on walks, reluctance to jump, stiffness after rest, difficulty with stairs or a change in temperament can all reflect joint pain, but none of these signs names a cause. Other bone, muscle, nerve and internal problems can look similar, and more than one problem is common in older dogs. Describe what has changed, when it started and whether good and bad days alternate; a short video of the dog moving at home is often more useful than a waiting-room demonstration.
Do not give human painkillers. Ibuprofen, paracetamol and similar products can seriously harm dogs, and a dose found online cannot be made safe for an individual animal. Pain relief choices belong to the treating veterinarian, who weighs the dog's age, other illnesses and medications. A dog that suddenly cannot bear weight, cries out or seems acutely painful needs prompt assessment rather than a wait-and-see approach.
Combine daily support with an individual treatment plan
For an overweight dog, gradual weight management can reduce joint load and support comfort, but the response varies and does not replace pain relief. Ask the veterinary team for a target body condition and a measured feeding plan rather than estimating portions. Ask the treating team to tailor the duration and type of activity to pain, mobility and other illnesses. Short, comfortable walks may suit some dogs; stop and ask for reassessment if lameness or distress worsens. Avoid sudden intense activity or a swimming programme without individual advice.
Adapt the home: non-slip runners on smooth floors, ramps or steps for furniture and vehicles, a supportive bed away from draughts, and raised bowls if advised. Keep nails short and trim fur between pads for grip. Physiotherapy, hydrotherapy and other supportive options can help some dogs when delivered by qualified professionals working with the treating veterinarian. Review the plan regularly, because needs change and what worked last year may not fit now.
Track comfort over weeks
A simple weekly record helps the veterinary team judge whether the plan is working: rising from rest, willingness to walk, use of stairs, play and sleep. Note good and bad days rather than single impressions. Report changes in appetite, vomiting, dark faeces or thirst while the dog is on prescribed pain relief, and keep recommended blood tests.

Preparing for a canine osteoarthritis consultation
- Record when these signs began and how they changed: Stiffness after rest; Reluctance to jump or use stairs; Shorter walks or lagging behind. Record appetite, water intake, toileting and any medicines or supplements.
- The listed urgency is prompt; worsening breathing, collapse, seizures or severe pain can make any situation an emergency. Ask the clinic rather than relying only on this category.
- Ask what else could explain the signs, which tests would change the plan and how discomfort will be managed. Symptoms alone cannot confirm this condition.
- Before going home, agree what to monitor, when to recheck and which signs mean calling sooner. Follow the individual treatment plan; do not copy another pet's prescription.
