Assistance dog candidates are generally selected with care for appropriate health, temperament and characteristics. Large established organisations such as The Guide Dogs for the Blind select and maintain their own breeding stock to ensure healthy pups with desirable traits.[5] Someone may carefully select prospect puppies from reputable breeders, or they may choose to commence training with a dog who was already part of the family. The reality TV show Rescue Dog to Super Dog featured the process of carefully selecting rescue dogs from shelters to train as assistance dogs.[6]
