Zeus having a bit of fun, lovely side gait but that tail, OMG! The tail should ideally not be raised above the level of the back, but it looks like no one has told Zeus that! Mind you he's not a show dog, so it doesn't matter and let's face it that is a tail to be proud of!
In case you haven't noticed, Zeus is not on a lead, just taking Ian round on a ball on a rope. What a star!
