Fur babies and newborn babies

Tere
I have the most adorable little Doxie. He will be two this coming February. But... I'm also 16 weeks pregnant. I'm a little bit concerned about having the two because I'm not sure if he's going to be a little jealous when baby gets here. He's already jealous of my boyfriend. How did you ease your fur baby with your newborn baby? My dog is pretty sweet and likes to cuddle and sleep almost all day (only wakes up to eat, go potty outside, get a little attention, and goes back to sleep). I know I would never leave the two alone, especially when he jumps so easily on the bed.
