Overview
Red, swollen paw pads often mean the paws have been irritated, rubbed, burned, cut or otherwise stressed. It can be something minor, but there are several possible causes, so it helps to check the paws carefully rather than guessing.
If the swelling is mild, your dog is still happy to walk, and there’s no bleeding or obvious wound, you may be able to monitor it briefly at home while keeping the area clean and dry.
Things To Check
1. Check when the redness started and whether it appeared after a walk, run, grooming session, hot pavement, mud, or time in grass.
2. Look closely for cuts, punctures, thorns, grass seeds, gravel, burns, scabs, or anything stuck between the toes.
3. Feel the paw gently for heat, tenderness, or a firm lump that seems different from the other paws.
4. Notice whether your dog is licking, chewing, limping, or holding the paw up more than usual.
5. Check if one paw is affected or if several paws are red, which can point to different causes.
6. Think about any recent change in walking surfaces, cleaning products, bedding, or grass treatment.
7. Watch for discharge, an unpleasant smell, broken skin, or swelling that seems to be getting worse.
Common Causes
Minor irritation is one of the most common reasons, especially after walking on hot, rough, salty or muddy ground. Friction, over-licking and small scrapes can also leave paw pads looking red and puffy.
Something trapped in the paw, such as a thorn, grass seed or small stone, can cause local swelling and soreness. In some dogs, an insect sting or contact with an irritating substance may do the same.
Less commonly, redness and swelling may be linked to an infection, an allergic skin flare-up or a deeper injury that’s not easy to see straight away.
What To Do
Start by gently cleaning the paw with lukewarm water and checking between the toes. If you can see a small piece of debris sitting loosely on the surface, remove it carefully, but don’t dig around if it seems stuck.
Keep your dog from licking the area as much as possible, and limit running or rough ground until the paw looks calmer. If the paw was dirty, a simple rinse and careful drying can help reduce further irritation.
Monitor for changes over the next 24 hours. If the redness fades and your dog is comfortable, it was likely a short-lived irritation. If it stays swollen, becomes more painful, or starts to discharge, it needs more attention.
When To Contact A Vet
Speak to your vet promptly if the swelling is sudden and severe, your dog is lame, the paw is hot and very painful, there’s a wound or puncture, or you suspect something is stuck deep in the pad.
You should also get advice if the redness is spreading, there’s pus or a bad smell, or the problem isn’t improving within a day or two of gentle home care.
Products That May Help
If your dog's paw pads are sore, dirty or irritated, a gentle pet care routine can be useful as part of keeping the area clean and comfortable.
