I've noticed in a lot of the pictures on this site that some people show their dogs in a show stack standing. Some throw the leash over the back, some let it dangle to the side, and some squat down.
Here in the United States it seems a lot of our professional handlers drop down below the dog so as to disappear instead of "hawking" over the top of the dog.
What is your preferrance and do your judges care? I had a judge yell at me once for not squatting behind my dog.
