My dog macy has been "pregnant" for 7 weeks. She looks pregnant and she acts like she is, but when we feel around her stomach we don't feel anything moving. She is eating quite a bit and she drinks a lot to. She pees almost every hour, but never seems to poop. For the last couple days she hasn't pooped and I'm getting worried. Is this normal for her not to poop? Is it bad for us not to feel the puppies moving yet?
