Rechargeable Rainproof Anti No Bark Shock Dog Trainer Stop Barking Dog Training Collar

Excellent fast delivery.As for the dog training, so far so good.We have a year old Belgian Malinois who is dog aggressive, all he needs is to hear the beep from the collar, it interupts what he's doing and he will then listen to you. We have yet to try him off lead with it. But I am quite impressed so far.
