A dog accused of mauling llamas in central Oregon was put to death Friday and his owner arrested for threatening an animal shelter director and fighting with sheriff's deputies.

Tazz, a 115-pound Akita-Malamute cross, received a lethal injection shortly after noon, ending a two-year legal battle by his owner, Ray Bowlin, 48, to save him. Bowlin argued the animal had been falsely accused and fought the case to the 9th U.S. Court of Appeals in San Francisco, which turned down his pleas on Tuesday. A last-minute effort to get the U.S. Supreme Court to grant a stay in the case failed.The Deschutes County Commission had ordered the dog destroyed under a county ordinance aimed at protecting livestock. The commissioners said Tazz was one of two dogs that attacked four llamas at the Patterson Ranch in January 1987. The llamas were disemboweled but survived the attack.
