Negative Positive
Title: pet training
Review: It didn't seem to work on my dog (big dog who is 11 yrs old) because when I pressed it he didn't seem to be bothered by it or his ears didn't perk up however when my daughter's dog who is only 5 yrs old came over and I pressed it, his ears jetted straight up! So I'm figuring it's his "older" ears that cannot hear it as well or it's not as sharp on his ear as a younger dog.
Is the review positive or negative?
