red lump behind front leg dew claw

Question
my female lab has gotten a red lump directly behind her right front dew claw, where the dew claw attaches to the leg. It almost looks like a pad growing. What could it be and should i take her to vets immediately?

Answer
Without a photo, I can't even guess.  Could be anything from a histiocytoma, which is normally benign and will eventually go away, to a cyst (maybe an impacted grass seed), to a tumor.  

If it's hard, it's most likely a tumor of some sort.

If it's soft and squishy, probably a cyst of some sort.

I don't know if this require IMMEDIATE attention, but it will require a vet to tell you exactly what it is.  

You could try a day or two of soaking the foot several times a day in epsom salts and then wrapping the leg with a ton of neosporin on the spot.  If it's a cyst, it might drain itself and heal.

But if you live and run your dog in an area where there are foxtails, you might want to consider a vet appointment sooner than later.
