The Great Pyrenees is a livestock guardian dog. They are happiest when working. They sleep a lot during the day and are on patrol most of the night. The Pyrs are bred to be independent thinkers and do best when the job of protecting the herd is left in their care. They have not let a predator such as a coyote or neighborhood dog into the pasture on our farm. Even a ten week old pup has a very ferocious bark. We have discovered that they will guard chickens as well as alpacas, cats, bunnies, and anything else that we introduce to them as part of the "herd". If they perceive a person to be of questionable character, they will quietly move between us and the guest or between the alpacas and the guest. Occasionally, the male alpacas will have an altercation and begin to fight. The Pyrenees that is in charge of the herdsires will grab the tail of the offending alpaca and pull him off the other one. We really appreciate the vigilence, loyalty, and affection of our Great Pyrenees. They allow us to sleep better at night.
