[NAGDU] the fetch command

[Madison Martin]

Hi all, I was reading a fictional book about these kids who visited a guide
dog school, and it talked about how the instructor was teaching the dog to
fetch a glove that he dropped while he was working the dog in harness. So I
was wondering, is this something that guide dogs are actually taught to do?
Or do you think that it was just made up for the book? I'm just curious
that's all. Look forward to hearing back from anyone who might be able to
provide an answer to this! Thanks
