What can be done to help a child get over a fear of dogs?

I would like a dog. My husband isn’t keen but has expressed an interest in getting a pretty mid-brown dog, Labrador type. (He encountered one recently and fell for its looks). But my younger daughter, who is 10, is terrified of dogs and has got really upset by the dog talk in our house. Not only is she very scared but is also very stubborn. She says that their teeth are very dangerous.

So we have put the dog-owning on hold, despite the concession from my husband. However, I would like to help her get over this fear that she has. Do you have any methods?

We have a friend who has two dogs, one older and the other a couple of years old. The older one she tolerates as he is laid back but the barky, jumpy younger dog causes her to get hysterical.
