I have a Chihuahua and a Boston Terrier/ Weiner Dog mix. They will both show an interest in the babies I have had in the house but have been trained to look but not touch. I would never leave the babies where the could reach them however if I was not in the room. Dogs will be dogs. They live fine with my big ducks however and have been trained not to touch them. I don't honestly feel it is the breed as much as it is the training they get when they are around them. Mine would never touch my ducks and are in the backyard with them every day but they had to be trained to leave them alone.
