I'm writing in regards to a blister I found on my dogs front

Customer Question

Hi there, I'm writing in regards ***** ***** blister I found on my dogs front left paw and there seems to be one possibly forming on his other paw. I was wondering if you happen to be able to guess where it was from. Could it be a foxtail or a splinter that became infected? I just soaked it in warm epsomsalt this evening. I'd appreciate your advice. Thank you!I added a photo below for your reference.

I'll follow up for Dr. D for you. Thank you for the photo. Yes, a foreign body abscess may have ruptured and evacuated itself. It doesn't appear that anything remains in that cavity. It's not unusual for multiple foxtails to be found in the paws - in different stages of abscessing. The main differential diagnosis is canine pedal furunculosis whose etiopathogenesis is unclear but one hypothesis is that sterile pedal furunculosis is a persistent, immune-mediated, inflammatory response to keratin and triglycerides liberated from ruptured hair follicles, sebaceous glands, and the panniculus (fatty layer of the skin). It's more common in short-haired breeds such as Vudu in which foxtails are less of a concern because there isn't hair between the digits which traps foxtails. The epsom salt soak was smart. You can continue soaking the affected paws twice daily for 15 minutes and see if these lesions resolve over a week's time but if more appear or you don't see a positive response to soaking, please have Vudu's vet take a look at the paws and mention pedal furunculosis to the vet who may not be aware of this vexing skin disorder.
