Overview
If your dog’s paw has suddenly become hot and painful, one common reason is that something may be stuck in it, such as a grass seed, thorn or small bit of debris. Other causes can include a cut, bite, irritation, infection or a sore nail, so it’s worth checking carefully rather than assuming it’s just a minor niggle.
Things To Check
1. See whether the paw is more painful after a walk, play, woodland access or muddy turnout, as this can point towards something being picked up outside.
2. Look closely between each toe, around the pads and along the nail beds for a thorn, seed, bit of glass, burr or other visible debris.
3. Check for redness, swelling, a small wound, discharge, scabs or a dog that keeps licking or chewing the same spot.
4. Compare the sore paw with the others for heat, shape changes or any sign that one toe or pad looks different.
5. Gently check the nails for cracks, splits, bleeding or a nail that seems loose or painful when touched.
6. Notice whether your dog is reluctant to bear weight, keeps lifting the paw, or pulls away when you try to examine it.
7. Think about recent grooming, trimming, running on rough ground or contact with something irritating, as these can sometimes trigger soreness too.
Common Causes
Foreign bodies are a frequent cause, especially grass seeds, thorns and small bits of grit or stone trapped between the toes or in the pads.
Minor cuts, grazes or a cracked nail can also make a paw feel hot and sore.
Sometimes the issue is irritation from something your dog has walked through, or licking that has made a small problem feel worse.
Less commonly, a deeper infection or an abscess under the skin can cause the paw to become noticeably painful and warm.
What To Do
Start by keeping your dog calm and preventing more licking or running around.
If your dog will allow it, gently part the fur and inspect the paw in good light. If you can easily see a small piece of debris sitting on the surface, you may be able to remove it carefully, but don’t poke around if it seems stuck or if your dog is very sore.
Rinse away dirt with clean lukewarm water and dry the paw well afterwards. If there’s an obvious cut or the area looks raw, keep the foot clean and limit activity until it settles.
Monitor the paw over the next few hours. If the heat, pain or limping is getting worse, or you can’t find an obvious cause, it’s sensible to get veterinary advice.
When To Contact A Vet
Contact your vet if the paw is very painful, your dog won’t put weight on it, there is swelling, pus, bleeding, a deep wound, or you suspect something is embedded. It’s also worth calling if the problem doesn’t improve quickly, or if your dog seems unwell in any other way.
Products That May Help
For paw and coat routines, a general pet care collection can be useful for keeping on top of washing, grooming and everyday hygiene around the feet.
