Overview
A red lump between your dog’s toes is often caused by irritation, a small injury, something trapped in the skin, or a grass seed getting caught in the paw. You can't tell the exact cause just by looking, but checking the area carefully can help you decide what to do next.
Things To Check
1. See whether the lump is on one paw or several, and whether it appeared after a walk, run, grooming session or time in long grass.
2. Look closely for a grass seed, thorn, splinter, cut, puncture mark, scab or any discharge around the lump.
3. Check if the skin is warm, swollen, painful to touch, or if your dog is licking, chewing or holding the paw up.
4. Compare the lump with the same area on the other paws to see if it feels similar or clearly different.
5. Notice whether the lump seems soft, firm, fluid-filled or open, as this can help you describe it to your vet if needed.
6. Check for mud, debris, matted hair or damp skin between the toes, especially after walks in grass or wet ground.
7. Watch for limping, repeated paw licking, swelling spreading into the foot, or any bad smell from the area.
Common Causes
Grass seeds are a common cause, especially if your dog has been in fields or long grass. They can irritate the skin and may work their way into the space between the toes.
Small cuts, scrapes or a trapped bit of debris can also cause a red, sore lump. Sometimes this starts as a minor irritation and becomes more obvious over a day or two.
Inflamed skin, a small cyst, an infected hair follicle or a paw pad irritation can look similar at first. Less commonly, a lump may be linked to a growth or another skin problem that needs a vet to examine it.
What To Do
Gently part the fur and rinse the area with clean lukewarm water if your dog will tolerate it. Pat it dry afterwards, because damp skin between the toes can stay irritated.
If you can see a loose bit of debris sitting on the surface, remove it carefully only if it comes away easily. Don't dig around in the skin or try to squeeze the lump.
Try to stop your dog licking or chewing at the area, and keep walks short until you know whether it is settling. If the paw gets dirty again, clean and dry it after exercise.
Monitor the lump for changes in size, colour, heat, pain or discharge over the next 24 to 48 hours. If it is getting worse, or your dog is lame or very uncomfortable, it should be checked by a vet.
When To Contact A Vet
Speak to your vet sooner if the lump is growing, oozing, bleeding, very painful, or if your dog is limping or won’t put weight on the paw. Grass seeds can sometimes move deeper into the skin, so persistent or worsening paw lumps are worth a proper examination.
