I understand your adoption dilema. With a baby in the house, I would advise adopting and older dog. They are much calmer than a puppy so would be a much better choice. A puppy is very active, likes to chew and has not learned any manners yet. I have adopted several older dogs over the years and have been very happy. I had an older dog when my last daughter was born. He would sleep next to her crib whenever she did and was very protective toward her. When you go looking for a dog, take the baby with you. See how the dog reacts around the baby. Find out from the shelter workers or th owner of the dog what kind of a temperament the dog seems to have. And never leave the dog and the baby alone unless the baby is in a playpen or a crib. It will take time for the dog to adjust to the baby but it will be well worth the time.
