A dog guide with barely any cane skills?

I'm studying to become an orientation and mobility specialist so thought this film would be interesting. It was unrealistic that the main character was considering (and I think ended up qualified for?) getting a dog guide when she had hardly mastered any foundational cane skills, which is a must to even be eligible for a dog guide as orientation skills are extremely important. She spent the majority of her time holding on to her aide - improper human guide technique - might I add, and the few times she used her collapsible cane it was poor: narrow arc, probably out of step (sounded faster that her walking pace), and her arm was dropped to one side (should be held at midpoint). She was scared about crossing the street (using an APS - but what about an intersection without one?) and it sounded like the idea of a dog guide (of which only about 1-2% of people with low vision or blindness in the U.S. have) would make her 'more independent' when she told her aide she would be fine now without him around all the time when she was getting a dog guide. This is not the case... the cane and dog guide are different modes of mobility with pros and cons. They're just different preferences (and can even be used in conjunction for certain tasks). Speaking of the dog guide, how the heck is she apparently qualified for one so soon after the onset of her mysterious blindness? No foundational cane skills or year+ long wait list? Just snap your fingers and you have yourself an expensive, trained dog guide? Ridiculous movie.
