Before my short foray into Gordon Setters and now my commitment to Whippets I bred and showed Kelpies originating from the Butterbone and Spectre lines.
Back in the 90's we would stack our kelpies, however these days most are free stood.
The Kelpie in the stack above looks to be a KLA Kelpie (back on Windari) of a nice type. I say this because of the two tone shading. And if that's the case the handler comes from show parents and has been doing this since he can walk, his mother has corgi's. (I could be wrong).
Looking down on the shoulders place feet evenly at the front, (you did this well) with your girl Myf don't stretch her rear end as much as she doesn't have as much length of stifle.
Kelpies are shown on a check chain and we would gather this up with a hand behind each ear, this would get the head up and show off the arch in the neck, (so rather than stretch out, move the head back to the shoulders and up) which is a requirement, tossing a treat gently out in front about 40cm will make the dog look and have that keen kelpie expression.
But since this is all for fun Myf go with whatever works for you.
