Lying on a bed and sleeping is easy - any young pup can do it,  but it takes years of practice and considerable skill to excel at the art of off-bed sleeping (the wolfhound equivalent of off-piste skiing), as Branigan demonstrates in a short master-class.
A Master Class in Sleeping
~ by Branigan
First, the elementary position,
a good starting point for those struggling with the concept.
. . . then a 90 degree roll establishes the second (intermediate) position.
The body is then turned parallel to the bed, allowing all four limbs to be fully supported . . .
. . . and the resumption of deep, satisfying, wolfhound sleep.
Warning: we recommend that young dogs attempt
this only under adult supervision.
The process begins with a gentle slide from the bed . . .
Next, the intermediate roll is reversed, so facilitating
a further slide onto the floor.
A full body twist is then performed (quite advanced, this) so that as the rear end slides off the bed, the front swivels round.
