Short answer: Sudden non-vocal limping in dogs is most often soft-tissue strain, a torn cranial cruciate ligament (CCL), a paw pad foreign body, or early stages of immune-mediated polyarthritis. Rest 24-48 hours; see a vet if it persists, worsens, or the leg won’t bear any weight.
🚨 Red flag — call your vet now if: Visible bone, open wound, leg held at an abnormal angle, or complete non-weight-bearing = emergency.
What you should actually do
- Most strains improve with 48 hours of strict crate rest + leashed bathroom breaks.
- Non-weight-bearing lameness almost always needs same-day veterinary evaluation.
- Check between the toes and pad – foxtails, grass awns, and cuts are easy to miss.
- Sudden hind-leg lameness in a medium/large dog after running = suspect torn CCL.
- Limping that shifts legs day-to-day suggests immune-mediated joint disease, not injury.
Dogs don’t always yelp when they’re in pain – many breeds are stoic, and dogs in chronic pain learn to mask it. The pattern of the limp tells you more than the noise. A dog that limps after running and improves with rest probably strained something. A dog that holds a leg up entirely and refuses to put any weight on it has either a fracture, a severe sprain, a luxation, or a CCL tear.
For sudden mild limping with a known trigger (a run, a slip, a fall): strict crate rest for 48 hours, gabapentin or vet-prescribed carprofen if available, and reassessment. If at 48 hours the dog is still limping, or if at any point the dog can’t bear any weight, you need imaging – X-rays at minimum. The most commonly missed diagnosis at this stage is partial CCL tear, which is hard to diagnose without a sedated drawer test or X-rays showing joint effusion. Catching it early matters because untreated partial tears progress to complete tears within months.
