SISTERS, OR -- Authorities are searching for a dog believed to be responsible for at least two attacks in the Sisters area, this month.

On Tuesday, a family in the Crossroads subdivision reported their small dog "Lexi" escaped her yard and was attacked by a black medium-sized dog wearing a multi-colored collar, near Bluegrass Loop and Crater Way. They were able to scare it off, but Lexi had to be euthanized due to her injuries.

The Sheriff’s Office is also investigating a report earlier this month of another dog attack. They say a dog being walked by its owner, near the same intersection, was attacked by a black dog on March fourth. In that incident, the dog received non-life threatening injuries. A deputy responded but wasn't able to find the suspect animal. 

DCSO is asking for the public's help in locating the black dog and its owner. Anyone with information is asked to call non-emergency dispatch at 541-693-6911.
