CARLTON  — A Ramsey County sheriff’s deputy accused of repeatedly hitting his police dog has pleaded guilty to a charge in Carlton County.

Brett Berry, 48, of Arden Hills was charged in June with animal cruelty and assaulting a public safety dog, both misdemeanors. He pleaded guilty to animal cruelty Tuesday, and the other charge would be dropped as part of a plea agreement.

Berry was staying at the Black Bear Casino and Resort with other sheriff’s deputies for K-9 certification trials in June when security video showed him beating his K-9 partner, Boone. Casino security staff told Carlton County sheriff’s deputies that Berry was asked by security to leave the resort lounge earlier that evening after customers reported “unwanted advances.”

On video, security observed Berry return to his hotel room and then walk to the parking lot with his dog. The video shows Berry getting upset with the dog and yelling at it before slamming it to the ground.

A criminal complaint said the dog appeared afraid of Berry and ran from him, getting stuck between two doors in a lobby vestibule. The complaint said Berry began beating the dog.
