Dog Sleeping On His Back

Why does my dog, a cocker spaniel, enjoy sleeping on his back?

Or why does any dog, for that matter.

I guess it must be comfortable for them. It just looks odd. :?

is so they can give you the money shot :-)

Aw, it's 'cause he loves you and feels safe with you. Or he's an exhibitionist. I vote for the former, though.

I'm not sure why dogs do a lot of things, but I agree with Anastasia on this one...your puppy certainly feels safe with you! Though I'm not sure what this means:

Our cat does that sometimes. It cracks us up. He just sometimes is on his back, legs in the air. We don't know why, but so funny.

jackson is all about the money shot (see the fuzza wuzza thread for his retrospective). Everybody else is right - it's a sign of trust when they expose their bellies like that

Aww, my dog (a large German Shepherd mix) sleeps on his back too. He sleeps against the wall, and his back paws are usually resting against the wall.

Oscar has to lean against the couch to sleep on his back. His chest is too big to stay in that position on his own.

completely unrelated: Weren't people told to have babies sleep on their backs to avoid SIDS?
