Ranger working on thresholds!

Ranger is a 10 month old Rottweiler puppy here for a two week board & train.  I trained him on his basic obedience and remote collar.  Ranger started as a nervous, insecure guy and in almost two weeks has become obedient and secure!  He loves running off leash and I love having the ability to call him back to me.  I think his Dad will be very happy with the new Ranger!
