My youngest daughter was brought home from hospital and put into her pram so that I could say hello to the dogs first. Baby cried, hubby went to pick her up ..............and was attacked by one of the dogs!

I had to grab the dog before she made contact. ;) (why did I do that? :) )Hubby was all set to punish her, but I wouldn't let him. After all, the dog was protecting the baby :D You just won't know how the dogs will react until baby comes home. All I can suggest is to be very careful. You will know the dogs best, or at least your parents will, so they will be able to watch the body language.
By the way, my daughter learned to walk using the dog as a climbing frame :D
