not working for dogs or cats can not recommend
This is awesome. Tried the barking collars with no luck but this device really works on our toy Poodle x bichon friese. Has definitely changed her barking at the TV when she sees other animals and stops her in her tracks when she here’s the next door dog bark and tries to join in. It really does make her take notice and stop to listen to your directions. Totally inaudible to the human ear. Best device for unwanted barking. Haven’t been in the situation to repel an aggressive dog yet. Yes I recommend but might not work for every dog. You can only try. Worth paying the cheap price to try!!
