I did a quick Google, so I know they can get them, didn't go any further 'cause I would rather hear from you folks than 'Wikipedia'. At this point I'm not even sure that is what he has on his pad, I haven't taken him to the vet yet. He licks it pretty often and for long periods of time when he does, to the point that, if I didn't know better, I might suspect he had piddled in the spot he was sitting. He gets it that damp with the licking. It looks and feels kinda like a raised callous. It's on the bottom of the pad. If it turns out to be a wart, what, if any, treatment is used for dogs? I had a plantar wart on the ball of my foot as a teen and the several "freezing" treatments were not fun:(
Could this have anything to do with the thyroid meds? Maybe he needs an adjustment in dosage?
Thanks in advance for any input.
