Is the Rat Terrier a good breed for inexperienced dog owners to own?

On the one hand Staffies are very good dogs with people, and especially children, and on the whole they are not aggressive towards people, which would make them good for inexperienced dog owners. But they can be stubborn and they do need discipline from the beginning and a lot of attention and training, so in that regards they may not be the best dog for inexperienced dog owners. Except if the owners take them to training from puppyhood.
