Video worked. That is what Maude did, when her butt/girly parts needed clean-or if she had an itch above her tail-and couldn't reach. Have you tried cleaning him? Scratching his butt, and above his tail? Does he have a tail pocket?
I am glad it finally worked. Duke gets a cleaning everyday. He must have still had a itch! Yes he does have a tail pocket that we have to clean daily or it gets nasty.I thought I was going crazy trying to get this to post!
I posted on your other thread about this ... could just be an OCD thing, that is what is was with our Nitschke... he dd not have a tail pocket so I know it wasn't an itch he could not reach - just bored was my guess.
