PREDATORS -- Stevens County officials have ranted about wolves and endorsed a coyote hunting contest, but free-running dogs are making the headlines for destruction to livestock and pets.

According to the Association Press, after the latest attack by a pack of wild dogs killed a 350-pound llama at Deer Park, the Stevens County sheriff's office is warning residents in the southern part of the county to protect their animals and families.

Deputy Keith Cochran told KXLY they are concerned because the dogs are cruel and bloodthirsty and killing for fun.

Since the end of March, there have been at least 15 attacks that have killed more than 100 animals. Dogs killed a number of goats last week and the llama on Tuesday night.

One resident, Temma Davis, says neighbors are worried about kids getting off school buses or riding their bikes.

The animal attacks have happened at night, but people say they are starting to see dogs in the early morning.
