That isn't safety

I used to have a Bernese Mountain dog/German Shepherd mix...he was huge and buff. My grandmother was walking him one day and a turkey ran across the road in front of them. My dog took off running and dragged my poor gma down a hill. The neighbors said she looked like Wonder Woman flying down that hill

If those dogs are properly trained, nothing will cause them to bolt.

I will never understand why anyone would want to crop dogs ears.
