2.5 year old, in tack male, started on livestock bred dog. Cant remember breeding but could find out if important. Started on cattle and sheep. Will herd them around but isnt finished. Very friendly, high energy!! Listens well, makes a big circle in pasture, but can get hung up on one cow. Will chase cats if not watched but can call off easily. Loads on pickup,SXS, and 4-wheeler. UTD on vaccinations. We are moving on from him because we dont use as much as we should.
