Title: This is not for stupid dogs
Review: After reading all the previous reviews, I had a feeling this might not work for all the dogs. But because all the other options were tried, I got one for my neighbor's wiener dog. The device worked properly, but this young wiener dog didn't respond at all. He kept barking regardless. I tried the device with several different ranges, but no, he was probably too dumb to understand it. There was a warning from other reviewers that this device may not work for small dogs, but better for medium size dogs. I hope this device will work for other people who have the same problem.
Is the review positive or negative?
