Review on 🐶 DEPPET 16.4ft Dog Training Device: Ultrasonic Barking Control, 3 Frequencies Immune-Proof, USB Rechargeable Trainer for Indoor and Outdoor Use by Dana Cardenas

Our two dogs bark at anything that happens outside our front window - especially the Revain van. (Oh what irony when this device got delivered - "Get it off your systems now, friends - this is literally the last time you bark at a delivery truck!") We started this last weekend - we Use the Quiet command and press the warning horn. We only had to use ultrasound once. It worked straight away - and now all we have to do is say "silence" and honk the warning horn to stop them barking. We are amazed! The ultrasonic sound also helped our dog friend stop jumping on people. Update 11/13/21: For the very first time ever we had a (relatively) quiet pizza delivery last night with no barking. A signal was enough. Unbelievable!
