I can totally relate! Both Winston and Champ are STILL dealing with their gross little warts!!! We're going on about five months now...... So, Winston was the first to show his; it was on his outter muzzle and grew to be HUGE (See pic below). We eventually had it taken off because it kept getting ripped open during Champ and Winston's wrestling matches!! Our vet told us that they are less likely to go away on their own when they are on the exterior. Having said that, most of Champ and Winton's warts on the inside resolved themselves within a couple of weeks.
I've heard that the supplement Lysine is supposed to help.
If they're getting big and are ripping open, I suggest having them removed. The procedure was pretty simple. Otherwise, I'd give them a bit of time.
Good luck!
