Dogs Judge Books by their Covers

Abstract
Some animals use warning coloration to frighten other animals. To see if animals respond to humans who wear clothing with animal-like warning patterns, 22 impounded dogs and 15 living in kennels were tested. Dogs responded more strongly primarily with submission to people wearing narrow, regular striped shirts than to those with wider stripes, with irregular stripes, with spots, or to non-warning patterns of similar composition. If people wish to evaluate the temperament of dogs for adoption, they should not wear provocative clothing.
