Overview
If your dog is walking on three legs, they’re usually trying to avoid putting weight on a paw, toe, nail or limb that’s sore or uncomfortable. It can be something minor like a small cut or something more significant, so it’s worth checking carefully rather than assuming it will sort itself out.
Common causes include a thorn, stone, broken nail, pad injury, a strain, or something stuck between the toes. Less often, it can be due to a sprain, a joint problem or another painful injury higher up the leg.
Things To Check
1. Notice when it started and whether it happened after exercise, a walk, play, grooming or coming in from outside.
2. Look closely at the paw, pads, nails and between the toes for swelling, cuts, broken skin, thorns, grass seeds, scabs or anything stuck there.
3. Compare the sore leg with the others for heat, obvious swelling or tenderness when you gently touch around the paw and lower leg.
4. Check whether your dog is licking, chewing or repeatedly holding the paw up, as that often points to local discomfort.
5. Look at the nail bed and claws for a cracked nail, bleeding or a nail that looks loose or twisted.
6. Think about whether the lameness is constant or comes and goes, and whether it’s worse on hard ground, after rest or after activity.
7. Check for other signs of pain such as whining, reluctance to jump, stiffness, a hunched posture or not wanting to walk much at all.
Common Causes
The most common reason is a minor paw problem such as a small cut, sore pad, something trapped between the toes or a broken nail. These can make even a normally calm dog carry the leg to avoid pressure.
Another common cause is a strain or sprain in the foot, wrist, elbow, shoulder or hip. In these cases, the paw may look normal, but your dog still doesn’t want to bear weight.
Sometimes the issue is irritation from rough ground, muddy conditions, heat, debris or a nail that’s become damaged. More serious joint or bone problems are less common but can also cause a dog to hop or refuse to use the leg.
What To Do
Keep your dog calm and limit running, jumping and rough play until you’ve had a proper look at the leg. If they’ll tolerate it, gently inspect the paw in good light and remove any obvious loose debris with care.
If you find a small superficial issue, keep the area clean and dry and monitor it closely. If your dog is only slightly reluctant to weight-bear and otherwise seems comfortable, short-term rest may help, but keep an eye on whether the limping improves.
If they don’t settle, worsen, or seem painful, it’s sensible to get veterinary advice rather than trying to push through it. A dog that’s walking on three legs is telling you something hurts, even if the cause isn’t obvious yet.
When To Contact A Vet
Contact your vet promptly if your dog is completely non-weight-bearing, the paw or leg is very swollen, there’s a deep wound or heavy bleeding, or the limp came on suddenly after an injury. You should also speak to your vet if it doesn’t improve within a day or two of rest, or if your dog seems unwell, distressed or in明显 pain.
