The natural return of the wolf has wreaked havoc on pastoral practices. In order to protect their flocks, breeders have put in place protective measures: the presence of a shepherd to monitor the sheep as well as the establishment of enclosures. To complete this measure, Pyrenean Mountain Dogs (Patous), used secularly, have been reintroduced to the mountain pastures. The word patou designates the dog’s protective role and not its race. The dogs generally used are Pyrenean Mountain Dogs. The patou protects the herd against everything he considers a predator, one of which is the wolf.
