Authorities say two German shepherds belonging to a western Montana police chief are being held in quarantine after attacking a boy.

The Independent Record reports the dogs belonging to Boulder Police Chief Rick Streib will remain quarantined a minimum of 10 days.

Boulder City Attorney Steven Shapiro says a complaint was filed to the police office reporting the dogs jumped a fence surrounding the police chief's yard on Dec. 13 and attacked a boy walking to school.

Shapiro told The Associated Press he hasn't yet received a report, but initial information is the boy may have been bitten. He didn't know if the boy needed medical attention.

Streib says he doesn't think the dogs are vicious and plans to follow procedures so they can be returned to his custody.
