A vicious dog attack left a Lecompton resident’s pet Chihuahua with life-threatening wounds Saturday afternoon. The Douglas County Sheriff’s Office responded to an incident about 2 p.m. in the 600 block of Whitfield Street in Lecompton after a loose Rottweiler wandered onto the property and attacked the Chihuahua, leaving it with serious injuries and puncture wounds.

Sgt. Steve Lewis, a sheriff’s office spokesman, said the Rottweiler was taken into custody and transported to the Lawrence Humane Society. The former rescue dog had a history of abuse by a previous owner, Lewis said, and a record at the Humane Society as a prior offender. The Chihuahua was transported to Bradley Animal Hospital in Lawrence.

“He’s got about a 50-50 chance of making it through,” Lewis said.

Douglas County does not require dogs to be kept on a leash at all times in public, unless they have been established as dangerous.
