Why did he hide? It wasn't because the collar hurt him. He hid because his whole world changed in that moment. For possibly his entire life no handler or owner has been able to stop him from running away. It is likely that this running away is why he ended up in rescue in the first place. He had to process this new reality where he ran away and yet I was still able to correct him. Eventually he came to me, exhausted and, if I am being honest, a little defeated. We walked back and he napped for over an hour.
Later in the day we took another walk and Loki was a different dog. He realized the major plus side to wearing a remote collar. How fast can a shepherd mix run? Very very fast. He zoomed around the field and when he found a deep snowbank he purposely dove face first into it over and over again. Whenever he began entering an off-limit zone I simply had to verbally call him back and he happily romped back to me and sat down. I did not have to use the remote once during the entire walk.
This is one of the reasons why I love remote collars. A dog who might otherwise not get to really run free outside of a fenced area and be safe gets to enjoy that freedom. Owners get to allow their dogs to run and play and be dogs without sacrificing peace of mind that they can get their dog back at any time (so long as the dog stays within the radius of the collar. In this case a 1/2 mile). I use them on my own dogs when we are hiking or going to a new place. If you have a dog who may not immediately be reliable with Recall a remote trainer is a wonderful second option. AND! In almost all of Lawrence (excluding Mass. Street) it is a legal leash.
