I think Koda will be fine, Michelle. So many of my friends have successfully added a baby to the mix when the dog was there first. And these are friends that REALLY loved their dogs/treated them like kings and queens before the baby.
None of that changed - the dogs are still part of their growing families. There were definitely some transitional issues, but that's to be expected. None of my friends had negative outcomes. In fact, every year, I look forward to seeing all the family christmas cards with the now-older dogs in the middle of the pile of kids, looking happier than happy.
I think most dogs are real troopers when it comes to adapting to new things. Especially when it comes to babies. The key for you - Koda is so well trained, and she knows her boundaries. That will be so huge for you in a very good way!
Here are some tips I can think of - buy your stroller a little early, and, as silly as this sounds, start walking Koda next to the stroller so she gets used to the feel of the wheels next to her. And of course, all those "textbook" tips of getting Koda used to the smells will definitely help. Get those diapers into the house early (they have a certain smell) along with some desitin, a baby blanket, etc.
You'll be fine. I am so excited for you - such a very special time in your life - treasure it!
