our pooch is the same way, he hogs the bed too. Luckily he is a small dog, half CArin and half Jack Russell. He looks just like "Toto" from the Wizard of OZ.
They certainly becoome an important part of one's life.

Now if we can just get Captain Jack, our black cat and him to share our kiing-size bed!!!
Jack meows "soulfully" until my wife or I get up and let him out at 4 AM. Has he got us trained or what!!
