Just saw this and wanted to say I too have a little boy that HUMPS .. Check out the video that was posted from the YORKIE TALK TEXAS MEETUP in WACO TEXAS.. The little boy doing the humping is my boy... Im proud of him yes but not for humping and we have tried everything... Hopefully he will grow out of it....
He also marks everything.. We love our belly bands... He marked peoples feet to every single chair to ever spot of pee if a pup peed he marked over it.. It was hilarious he sure keeps me busy!
I use command words...
NO HUMP
NO MARK
and it works but in a crowd of people at a meetup I AM NOBODY HE IGNORED ME
