Predation is a major problem faced by domestic sheep ( aries ) and goat ( hircus )

producers in the western United States. Producers have been incorporating livestock guarding

dogs ( familiaris ), llamas ( glama ), and donkeys ( asinus ), which appear to be

effective in reducing these mortalities. The increased use of guarding animals to mitigate predation

on livestock may reduce animosity toward predators and result in more positive attitudes

toward the conservation of carnivores.
