A few weeks ago I ordered an ultrasonic dog repeller from an Asian dealer and it finally arrived this week. It wasn’t very expensive. I think one reason why is because this product has never been scientifically tested to prove that it works. The reason I say this is that this product apparently is not sold (legally) in the U.S. because it is considered to be ineffective.
I bought a cheap 9 volt super heavy duty battery at the dollar store and put it in the repeller. I aimed it at a female chihuahua, and pressed the button. It got her attention immediately. But not what I had expected. She looked at it and her ears pointed at it, and she turned her head from side to side, but didn’t make much of a fuss, and she didn’t turn and run. It looked like my first attempt at repelling a dog ended in failure.
I bought a squeaky toy, mainly because I plan on putting a Blue Blinky inside of it (later blog). It’s a green octopus made from translucent plastic. I had to remove the squeaker to make room for the battery and circuit. I tried the squeaker on the two dogs (above) and got much better results than with the ultrasonic dog repeller. They hear the loud squeeeeek! and they’re running away! They don’t like it at all! :-))
