My Boo is sick

My dog has been sick tonight.  He never poohs in the house and he did tonight.  He couldn't even get up to go out.  He just laid on the floor and let go.  Cleaning up wasn't so bad this time.  At least it wasn't full on liquid.  But between the throwing up and poohing... he was one sick baby.  I just wish I knew what was wrong with him.  He would barely move.  He didn't wag his tail. At least he has started to feel a little better... I think.  He is moving around some and going out to use the bathroom.  So I wonder what had him sick.  I do know that if he doesn't act like his self tomorrow, I'm liable to take him to the vet.  Alicia takes sophie and duchess to Baird's... that might be where he ends up.
