TJW Adjustable Ultrasonic Outdoor Dog Bark Controller, Dog Anti Barking Birdhouse Shape 4 Levels

I have a Yorkshire Terrier who loves to bark at noises and birdsI purchased this and followed instructions this does not make anydifference. likewise with the bark collar and the batteries do notlast very long. All these products are waste of money and will only get overthis problem with training.

We purchased this to try and control neighbours dog barking but can't hear anything coming from it, even at the highest setting. We purchased dog training whistles instead which you can definitely hear the high pitch (although this hasn't worked on the neighbours dog either!)

hasn't stopped next doors dog howling . why do people with dogs think its OK to have dogs barking all the time.if you have one of those for a neighbour don't bother with this.

It seemed to work at the beginning but has never worked since a complete waste of money

Don’t work waste of money

This really works amazing

Great
