Sometimes it's the obvious!

For a while now Rosie has been sitting to far forward on the 'return to heel' - I was just doing some dumbell throws (in the kitchen no less, sorry fridge for the bump) and a lightbulb went off in MY head to click when she was nearly in position, ie., she went round behind me and I could see her face at my left and clicked - she was in stand rather than sit. Two more times in stand and then I just waited and 3 secs later she offered a sit, in perfect position. Three more perfect returns with a sit - we ended with a jackpot. She must have thought I was an idiot :)
