Handheld Dog Repellent, Dual Channel Electronic Animal Repellent, Handy Ultrasonic Dog Deterrent for Outdoor Camping Garden, Bark Stopper + Good Behavior Dog Training

This is by far the best training device I have used with my dogs. We have 2 toy poodles that are 8 and 2 years old the they will bark uncontrollably when the doorbell rings or when someone goes by outside.With this device I just quickly press the button while saying “no barking” and the stop immediately. It must be VERY loud to them, so I have been using it sparingly, but it is well worth it.

Didn't work on my dog but my cat hates it.

Didn’t do anything but make my dog look at it funny then start barking at it

Worked for what seemed like a day or two then noticed that it started having less effect and the dogs barked through it. The power button eventually caved in and this was returned for a refund.

So far works well with a range of twenty feet. Use it for barking dog next door by my bedroom window. Price was good but got new battery for it.

This gadget really works! Now all I have to do is look at it and my dogs stop barking. Also it is good for when I walk them--for use on other dogs behind fences.

After a couple of uses my Yorkie understood not to jump on his elderly, deaf, blind housemate. Now I just hold it up and he walks the other way.The only issue was once we installed the battery the back would not fit back on. The opening to slide the back into is actually below the battery line so there is no way to secure the back. Still works we just taped it closed.

Very cheap. Button pushed in too far after one day and could not be placed back into position even after taking it apart
