Here's just a little vid we did over the Holidays, not great, but it was a nice little first start for a dual heel (is that what they call this? dunno :)
Anyway, we're much better at heeling individually. Sometimes when we heel together like this, we think we need to get Mum some Blue Cross Blue Shield, 'cause we get kinda wacky and start tripping her up, BOL! But then we settle down into a rhythm, and it works fairly well.
Mum thinks we need to do this more, she loves the tandem tricks we do!
