We have two cats and a dog...but we're talking about finding new homes for the cats

I love them to death, but we *just can't* keep the dog from thinking they are toys and running around the house chasing them. They have their claws, and they've scratched the dogs nose on more than one occasion, but she just doesn't learn. She thinks the cats are the best toys ever!! So now, one cat spends all his time under the bed, and we never see him except at feeding time, and the other one spends all her time on the top shelf of our closet. We were talking about rehoming them before we were even trying to get preg, but have been hoping we could teach the dog, and give the cats some semblance of a quality of life. But it hasn't happened.
I'm not at all worried about the dog and the baby though. She has already demonstrated that she is great with kids, and she is (usually) very obedient. Though I know I'll get some weird looks from the neighbors when I start taking walks with an empty stroller to get the dog used to walking with it!!
