Had one before and someone took it off our dogs neck. Therefore had to purchase another.It is the only thing that he recognises and does 99% of the time stops him barking.

It is very good it works to calm the dog down and found it to be very successful.

Would highly recommend adopted an eleven month lab... using the coller we now have her under much better control.Only down side it needs to be waterproof land love to swim.

Works well from good distance

This collar is an excellent training aid

It worked like a charm...
