nacho came rushing up to me, trying to jump in my lap, licking his paw and running in circles. after some bending and twisting i was able to see what looked like a giant zit in between his paw pads. he had licked it so much it was soaked and pink. he was limping and sad.
i dissolved some epsom salt in warm water and he put his paw in the bowl for a few minutes. i dried off his paw and put antibacterial ointment on the spot. i did this every 4 hours or so and by the next day it was a scab. the next day it was gone.
just a tip.
