A new baby in the house can be very stressful for new parents, especially if there are other children to care for. You might feel that you no longer have time for your pet, or the pet might be a danger for your child. Don't believe any of the old wives' tales about animals being vindictive and jealous towards children, most pets accept new children when it's handled correctly, and if you are prepared to work with your pet. Most problems result from pack order problems - the dog does not want to relinquish his status in your "pack". You should start well before your new arrival. You might want to speak to a professional behaviorist if you think your pet might be "jealous" of your child.
