Children Under age 2 Children under the age of two really aren't aware of the dog as a real presence. Although they may talk to the dog and call it by name, the dog doesn't really mean any more than a stuffed animal. At this age the dog considers the child a potential littermate. Playing with the child as it would a puppy from its own litter. You must teach the child to respect the dog and the dog to behave properly with the child.
Supervision is mandatory whenever an infant and dog are together.
Separate the child and dog if play gets to rough or you feel the dog is getting tired or uncomfortable. Don't relegate your dog to the back yard. He is a family member and deserves and needs to be with you. Behavior problems won't be corrected by barring the dog from the house. Take time to spend a few minutes of quality time with your dog each day.
