Overview
If your dog has a cut on its leg, the first things to check are how deep it is, whether it’s still bleeding, and whether the skin around it looks swollen, warm or sore. Small grazes and shallow cuts are fairly common, but there can be several causes, from a scrape on a fence to a paw or leg rubbing against something rough.
If it looks minor, you can usually start by keeping it clean, stopping your dog licking it, and watching for any change over the next day or two.
Things To Check
1. Check whether the cut is still bleeding or whether the blood has already stopped and formed a scab.
2. Look closely at how deep the cut seems and whether the skin edges are slightly open or gaping.
3. Check the skin around the cut for redness, swelling, heat or tenderness when touched gently.
4. See if there’s any discharge, dirt, grit or a bad smell coming from the area.
5. Watch how your dog is moving. If they’re limping or avoiding weight on the leg, that can give a clue about soreness.
6. Check whether your dog is licking, chewing or rubbing the area, as this can make a small cut worse.
7. Think about what may have caused it, such as a rough surface, a sharp edge, a thorn, a nail or a scrape during exercise.
8. Look at the whole leg, not just the cut, to see if there are other small grazes, swelling or bruising nearby.
Common Causes
The most common cause is a simple scratch or graze from everyday activity, such as running through undergrowth, brushing against fencing, or bumping into furniture or garden items.
Sometimes a cut on the leg can come from a claw, a thorn, a small bite, or a rough patch of skin that’s been rubbed repeatedly.
Less commonly, a cut can be linked to a deeper puncture, something stuck in the skin, or irritation that’s been made worse by licking or scratching.
What To Do
If the cut looks small and your dog seems well, gently rinse it with clean lukewarm water and keep the area as clean as you can. Try to stop your dog licking or scratching it, and limit very muddy or rough exercise until it starts to settle.
Check the cut again later the same day and over the next 24 to 48 hours. If it looks cleaner, less sore and no longer active, that’s reassuring. If it becomes redder, wetter, more swollen or more painful, it’s sensible to speak to your vet.
If you can think of what caused it, removing or avoiding that hazard can help prevent another small injury.
When To Contact A Vet
Contact your vet if the cut is deep, won’t stop bleeding, is gaping open, or if your dog seems very sore or lame. You should also get advice if you notice swelling, pus, heat, a smell, or if the wound doesn’t start looking better within a couple of days.
It’s also worth calling sooner if you suspect something may be embedded in the skin, or if the cut is on or near a joint and your dog isn’t moving the leg normally.
