Common Causes
Osteoarthritis
Schedule Vet VisitThe most common cause of joint stiffness. Cartilage breaks down over time, causing inflammation and pain. Affects 80% of dogs over 8 years. Worse after rest, better with gentle movement.
Hip Dysplasia
Schedule Vet VisitMalformed hip joint causing progressive stiffness and pain in the rear legs. Genetic but worsened by rapid growth, obesity, or overexercise in puppies.
Elbow Dysplasia
Schedule Vet VisitDevelopmental abnormality of the elbow joint causing front leg stiffness and lameness. Common in large breeds.
Previous Injuries
Schedule Vet VisitOld injuries to joints, ligaments, or bones can lead to early-onset arthritis and stiffness, even in younger dogs.
Lyme Disease
Schedule Vet VisitTick-borne infection that can cause joint inflammation, shifting stiffness between legs, and lethargy. May come and go.
Immune-Mediated Polyarthritis
See Vet ImmediatelyThe immune system attacks the joints, causing stiffness, fever, and pain in multiple joints. Less common but can affect younger dogs.
Spinal Issues
See Vet ImmediatelyIntervertebral disc disease (IVDD) or other spinal problems can cause stiffness, reluctance to move, and changes in posture.
Muscle Soreness
Monitor at HomeOverexertion from unusual activity can cause temporary muscle stiffness that resolves within a day or two.
How to Photograph for Best AI Analysis
Getting a clear photo helps our AI provide more accurate insights. Follow these tips:
- Record video of your dog getting up from lying down — this shows stiffness clearly
- Film your dog walking after rest and again after 10-15 minutes of movement
- Capture the first few steps when your dog wakes up or gets up
- Show your dog attempting stairs or jumping (if they still try)
- Film from multiple angles — side view and behind
- Note any changes in posture like hunched back or lowered head
When to See a Veterinarian

- •Stiffness is severe — your dog struggles to stand or walk
- •Sudden onset of stiffness (was fine yesterday)
- •Stiffness accompanied by fever, lethargy, or loss of appetite
- •Your dog cries or yelps when moving or being touched
- •Stiffness is progressively getting worse
- •Your dog is having accidents because they can't get up in time
- •You notice muscle wasting (legs looking thinner)
- •Stiffness in a young dog (under 5 years)
