Dog becomes seeing-eye for his best friend – another dog

File photo shows Amos (right) and Toby. Amos was born blind, but he is lucky to have his own guide dog – Toby, who is a border terrier. He defends Amos from other dogs and helps him find his water bowl. Volunteer Jess Martin, who has had Toby for the past nine years, adopted the blind Amos from a rescue center in North West England last year. She said Toby was a bit wary of Amos initially, but he soon ended up becoming this adorable blind pooch's best friend. [Photo: IC]
