Those with dogs...

Erika • Finally preggers! Can`t wait to meet my new valentine. <3
I have two chihuahua puppies. 4 months old. And for the past week even before I found out I was pregnant they have had to be right next to me. They even get into bed go right under the blankets and curl up right next I my bloated belly. They will cry and cry and cry if they can't be laying on me or near me. Do they know? Is this really weird?
