I can't beleive it was this easy ! I have purchased in the past a dog training collar that you pressed a button to send a shock to the dog when it did something wrong.... This was a little bit to hard for me to handle and felt it was a bit cruel, but that's just me...But I needed my dog to stop jumping on people when they came over or when I came home.... I studied this subject pretty intensley when I came across this particular product by watching a lot of YouTube videos ! Much to my surprise, it seemed to easy but it was exactly that !! I Highly Recommend this Dog Clicker Trainer !!!
