When you introduce dogs and children, do it very carefully. Advise your child to be gentle and offer your dog a treat. Never allow young children to sit on the dog, pull his ears, hairs, or tail. Tell them not to run from the dog, scream sharply around him, stare at him, or hurt him. Never allow your kids to pick on your rottie. Here are other things that you should keep in mind before you bring a baby and a rottweiler together:
1) Before you introduce the baby to the rottweiler, the dog should already be fully trained on how to "stay" "sit" and "lie down" on command.
2) Make sure that the rottweiler is secured on his leash the first time that you introduce him to the baby. You can muzzle the dog if you are still uncomfortable with the leash. The problem with this is that you do not want him to associate muzzling with the baby. The dog should already be familiar with the having the muzzle on before meeting the baby.
3) Keep the dog away from the baby during the baby's first few days at home. Let the dog get familiar with the smell and sound of the baby. You need to be very careful during this time because some dogs may not comprehend that you have a new small human in the house and not a "prey animal".
4) Have the dog sit and stay before you bring the baby to the room and then reward the dog for staying. Move the baby closer to the dog while rewarding him for his good behavior. Once you are secure about the dog2s comfort level, allow him to sniff the baby. But remember, you should never leave the dog and baby alone together during the baby's first few weeks at home.
