Guide Dog T-Shirt - Many service dogs are retrievers, but the one here looks like a German Shepherd to me. Dogs can be trained to help humans in many ways, from guiding the blind, to aiding search and rescue work, to providing comfort to the old or ill. The idea of guide dogs dates back to at least the 1500s, but was not terribly common until World War I when Germany established training schools to provide guide dogs to blind veterans. It wasn't until the late 1920s the seeing eye dogs gained any acceptance in the United States. Honor our canine companions with this helpful guide dog t-shirt!
