unfortunately it won't though hun!
People think 'ohh my dog is soft as butter it would never turn' but unfortunately it is a dogs nature to protect itself when it feels threatened and they only have teeth and claws with which to do this.
i have a dog and a baby, and yes normal my dog is soft as butter but that doesn't mean i would ever leave her in the room with my dd. dp and i have gone out of our way to make sure that she cannot get up on to anything in the kids bedrooms. DSD and DSS both have high sleeper beds and there is nothing near DD's cot that she can climb on.
We have taken an immense amount of time to slowly introduce the dog and the baby and the older kids. she is very good, and we sit with baby on one of us and the dog on the other, keeping her head away from baby and gently guide baby's hand to stroke and we remove it if she tries to grab at the dogs fur etc. we also are very careful now we are weaning dd that the dog is not near her if she is sat on the floor or one of us when she is eating (although she is a bloody good hoover). the dog gets lots of treats for being good and staying away from baby when she is told to and she gets told off and sent to her bed when she misbehaves. we also have a cage that she can go and hide herself in when things all get too much for her and both DSD and DSS know not to go near her when she is in her bed or cage as that is her 'safe' space.
she is a rescue dog and although we were told she had come from a loving home we don't believe it for a second due to some of her behaviours and her abject fear of all men. she is terrified of men's feet, high vis jackets and men in wooly hats - she doesn't become aggressive (that we have seen) but she does bark a lot and back away.
