A dog that suddenly starts limping gets your attention fast. Limping can range from a thorn in the paw to a serious joint injury, and figuring out the cause matters. Here's what to look for.
Start With the Paw
The simplest explanation is often the right one. Check your dog's paws for:
- Thorns, glass, or splinters stuck between the pads
- Cuts or abrasions on the pads or between toes
- Burned pads from hot pavement (common in summer — if it's too hot for your hand, it's too hot for their paws)
- Broken or torn nails — especially painful if the quick is exposed
- Swelling or redness that might indicate a sting or bite
If you find something minor, clean the area and monitor. Anything deep, bleeding, or swollen warrants a vet visit.
Soft Tissue Injuries
Dogs can sprain or strain muscles and ligaments just like people. Playing too hard, jumping off furniture, or an awkward landing can cause a soft tissue injury. These usually show as:
- Mild limping that gets worse after rest
- Reluctance to put full weight on the leg
- Improvement over a few days with rest
Common Orthopedic Conditions
When limping persists or comes and goes, a structural problem may be the cause:
- ACL/CCL tear — The cranial cruciate ligament (the dog equivalent of the human ACL) is one of the most common orthopedic injuries in dogs. Signs include sudden lameness in a back leg, sitting with the leg kicked out, and difficulty rising. Often requires surgery.
- Luxating patella — The kneecap slides out of place, common in small breeds. You may notice your dog skip or hop for a few steps, then walk normally again.
- Hip dysplasia — A genetic condition where the hip joint doesn't form properly. More common in large breeds like German Shepherds, Labradors, and Golden Retrievers. Causes stiffness, bunny-hopping gait, and difficulty with stairs.
- Arthritis — Degenerative joint disease affects many older dogs. Limping is often worse after rest and improves with gentle movement. Cold or damp weather can make it more noticeable.
When It's an Emergency
Get to a vet immediately if your dog:
- Won't put any weight on the leg — non-weight-bearing lameness suggests a fracture, severe ligament tear, or dislocation
- Has a visibly deformed limb
- Is in obvious pain — crying, whimpering, snapping when touched
- Has sudden swelling in a joint or limb
- Was hit by a car or had a fall
Age-Related Considerations
Puppies and young dogs are more prone to growth plate injuries and conditions like panosteitis (growing pains). Senior dogs are more likely dealing with arthritis or degenerative conditions. Middle-aged, active dogs are the typical CCL tear candidates.
What to Do While You Wait
If the limp is mild, restrict activity (no running, jumping, or stairs), and observe for 24 to 48 hours. Don't give human pain medications — ibuprofen and acetaminophen are toxic to dogs. Your vet can prescribe safe anti-inflammatory options.
