After reading about Ketschker's turns online I decided to give them a shot with our dogs.
First of all, the best way to describe a Ketschker is to say that it is a combination of a front cross followed by a blind cross. You set it up by starting to front cross but you don't complete it and instead finish with a blind cross. But, you don't actually switch sides of your dog.
Sounds confusing...it makes more sense to see it.
I had heard that it really benefits dogs with longer strides, which surprisingly is true of my Lexi. It is said to make turns more efficient and to increase acceleration out of the turn.
