Congratulations to all!
I've been giving this one some thought. I wouldn't worry too much about how the dog is going to "feel" about the baby. I would focus on strengthening basic training and -- VERY KEY -- logistics.
I have never juggled dog & baby...but I have juggled babies and toddlers, and I have juggled a puppy and three young kids. So that gives you some sense of my perspective.
Here are some ideas on logistics:
(1) Get your V used to sometimes pottying outside on his own. Now would be a great time to install a fence! There are going to be times when the dog needs to pee and your hands are very full. You will be sooooo glad to open the door and let him out into a safe environment.
(2) Get a comfy glider where you can sit, rock, & feed the baby. Train your dog to lie on a dog bed or mat within your reach while you sit in the glider and read a book or whatever. The dog should LOVE having you sit in the glider not paying too much attention to him (because you are very occasionally handing him great treats!).
(3) Let your V spend time in his crate while you are home. Don't be a wimp about this. It is good for both of you. Keep frozen kongs or chewies on hand and work on a rock solid "kennel up" command. You will sometimes need to get the dog out of the way in a safe place -- immediately and without fuss. Get everyone used to it now.
(4) Have some chats with your spouse about where everyone is going to sleep. Does the dog sleep in your bed? Is he in your bed because you *want* him there or because you couldn't bear to have him cry in his crate? FYI, many babies do NOT happily drift off to sleep alone in a crib.
Work it out now before you are too tired to think straight....
(5) Partition the house with baby gates now, so that you can easily either separate dog from baby OR keep dog with you when you are stuck somewhere caring for the baby. You don't want him in the upstairs garbage while you are bathing baby in the downstairs sink or swiping things off the counter while you are putting baby down for a nap. My guess is that a V will be as smart as a toddler in terms of sensing (and seizing!) opportunities to misbehave. :
I'm sure that there are plenty of others...but that's a start. Maybe others have even better ideas to add.
