Youngstown police are investigating the death of a 3-day-old infant after being bitten by a dog.

The mother of the infant tells 21 News that her baby was on the floor at the time of the incident.

Introducing a baby into a home with a dog isn't always an easy task. The American Society for the Prevention of Cruelty to Animals offers tips on how to make it easier.

The ASPCA says that teaching dogs skills to interact with an infant and preparing the dog for new experiences are important.

Making a plan for the new arrival in the family is the first thing the ASPCA says should be done. This includes teaching the dog basic obedience skills, gradually introducing the dog to new sights, sounds and smells and anticipating changes in any daily routines that affect the dog.

The organization lists basic manners that they consider the most important: the commands “sit,” “down,” “stay” and “wait;” teaching dogs to leave things alone and set down things they might be holding; greeting people politely; crate training; and how to come when called.

Along with teaching basic obedience skills, the ASPCA recommends that owners prepare their dogs for lifestyle changes, such as a change in the daily routine. This can mean varying feeding times, walking times and waking up in the middle of the night.

The ASPCA also says that dogs should be introduced to new rules before a baby arrives, such as no jumping or not being allowed on the furniture.

Introducing dogs to new sights and smells associated with a baby will help the pet transition easier, according to the ASPCA. They recommend unwrapping new baby supplies, such as toys, car seats, high chairs and swings, and introducing them to the pet one at a time.

Dogs should also be trained for instances when a baby tugs on its ear or tail and for the baby's movement. The ASPCA says dogs need to learn to view these as positive experiences, by the owner gently tugging on the dog's ear and then giving it a treat. The organization also says that getting on the floor and crawling toward the dog should help the pet become accustomed to a baby's movement.

The organization says planning the first meeting between the dog and the new infant is crucial. They address that new parents may feel nervous about letting the dog have extended interaction with the infant. The ASPCA recommends putting the dog on a leash and allowing it to sniff the infant for short periods of time. After a good interaction, the dog should be rewarded with treats.

They warn to never force the dog to interact with the baby. They say letting the dog approach the baby on its own is best.

If the dog seems aggressive toward the baby, the ASPCA recommends finding a professional trainer or behaviorist to help train the dog. They say that punishing an aggressive dog physically or verbally can backfire by causing the dog to associate the bad things with the baby being present.
