Well, as you might remember, as soon as I got rid of the warts on Scamp, Jazz got 'em. I've been putting Desitin on them as Anita suggested, and they were staying the same or getting less. Finally, talked my vet into giving a shot for it, and it seems to be working. She had only two warts on her last night, and she just got the shot Monday.
I told him he needs to keep that mess handy, just in case! Just thought I'd pass it along, though. He did say with some horses it works; others it doesn't.
