Indeed and its more likely that a trained dog will do as its told than the untrained one she had no problems with.
Its also pretty incredible that a dog won't be found to match the Dorothy and won't be trained to work with that Dorothy. Fitting the Dorothy to the dog would be like fitting the Dorothy to the slipper. If they can be trained to jump through fire or run at people with weapons, trotting beside a teenage girl shouldn't require too many doggy titbits.
