Just because Baby lives with two dogs doesn't mean that he is comfortable with all dogs. This weekend, we took Baby with us to a friend's house. Our friend had a small, hyper dog that loved to play fetch and never sat down. For some unknown reason, Baby started crying when he was around that dog. We have no idea why the dog upset him, but it did. The dog wasn't mean, didn't bark, and ignored Baby. At first we were really puzzled as to what was making Baby upset. But we guessed it was the dog, And our suspicions were confirmed when Baby was perfectly fine as soon as the dog was put away in a bedroom.
So just because your baby or child grows up with dogs doesn't mean that he'll be comfortable around every dog.
