My dog has had the training three times. We have always been concerned that it would work in the real world because she is very curious and loves to chase lizards or anything else that will run. Two days ago while on a walk with my wife our dog stopped and pionted at the base of a large bush. This was her first encounter with a rattler and when that snake started to buzz she, the dog, took off in the opposite direction. What a relief to know this training worked for our dog. The dog came home but I think my wife is still running. Ed
