I killed an even dozen off a dead horse the year I got my 17 Hornet. But I split him open to allow some gut to fall out and then drug him behind the tractor for a few miles to lay a scent trail. Have another cripple that needs put down, and I should probably shoot him and do the same. Had a vet put down my kids pony one year and the coyotes wouldn't touch it. I reckon the drug made him smell/taste funny......
