Excellent - love it when they get each other back!
Bella's got a friend who's a beautiful blue merle rough collie called Sassie - Bella really loves her, literally does full bum wags when she meets her. Anyway they always have a good wrestle and Bella loves to just bury into her fur and pull at it - last time they were playing like this and Sassie worked out a really good use for Bella's ears - got her on her back so that her ears were splayed out on either side, and then placed a paw on each ear and pinned her down by them!
It didn't last long though, Bella wriggled and kicked her little legs like crazy and soon escaped, she is a llittle houdini!
