Title: Do not use !
Review: I placed this collar on my dog it took several barks from him then all of a sudden he yelped really loud and all 4 paws left the ground, he leaped about a foot into the air. I instantly removed the collar and had to calm him down. I never put it on him again this is not the way to train a dog it's cruelty. I felt so bad I did this to him. I sure wouldn't want 2 prongs sticking in my neck shocking me.
