Title: Didn't phase my dog
Review: The first time I tried this, I had to press the button several times before my dog even noticed it. And then, he only did so with mild interest. My dog is a Great Dane though, I don't know if it makes a difference, but from what I've read it seems to work well on smaller dogs, and that may mean that smaller animals have more acute hearing. For instance, my cat HATES it. His ears fold back and he runs off. I was really hoping this would work for my big boy, but he really doesn't seem to care.
Is the review positive or negative?
