CLARK COUNTY, Kan. -

A dog owner in western Kansas said he's not only mourning the death of his dog, but he wants justice.

Justin Underwood said his 9-year-old Border Collie, Mac, ran away from home last week. The dog ended up in a goat pen. Two days later he received a call from a woman, saying she had shot the dog because it was harassing her goats.

"There was no gun shots evident, no metal fragments, no nothing in the x-ray, and at that point we went to the sheriff's department because things weren't adding up," Underwood said.

The Clark County Sherriff's department sent the dog's body to a research lab at K-State. Results showed the dog had been strangled to death.

Underwood said Mac was trained to herd cattle, and would not have been dangerous to other animals. He does not understand why the woman killed the dog. He told Eyewitness News Mac had a collar, and was microchipped.

She faces possible misdemeanor charges.
