If introduced correctly, there shouldn't be any problems with your dog and the baby. Chances are that if you greet the dog in your usual manner when you return from the hospital, he/she will be okay. But, remember that the dog was here first and may react just like a first child would. Give him/her the same amount of love and affection that you did before the baby was born and you will be fine. Yes, there are precautions you'll need to take when having a baby, but getting rid of the dog isn't one of them. In fact, it is unfair to deny a child from growing up with a dog. There is no better way to teach a child how to be loving and compassionate.
