Review on Ultrasonic Dog Deterrent - Dog Dazer II by Nicole Cook

As delivery drivers, we are always exposed to all sorts of dogs when delivering packages to houses and apartment buildings. Dogs always run to the front gate/front door and bark uncontrollably. Some of us have even been bitten because owners don't keep their pets on a leash when they are supposed to walk their dogs. So I decided to try this product to see if it would help on my shipping routes. Unfortunately, this product didn't live up to its name. The dogs just kept barking and barking and "didn't walk away". I think it's more educational than deterrent. During my 10 hour shift I must have tried this device on 30-40 dogs without success.
