Generally such an attack is caused by jealousy. If the baby is a new addition to the household and takes up a lot of the parent's time and attention which had previously been given to the family pet they will understandably resent the interloper. Try to show the dog it is still loved and important to you and introduce it to the baby while demonstrating affection to each to link them both with you. The dog should twig that he is not excluded and accept the new addition.
Rabies maybe, ask a vet or a trainer.
If you are talking about the pet dogs such as bulldog or sheepdog they can never attack.
