Query: Horrible collar

We bought this collar as a replacement for an innotek one that broke. This collar is inhumane. This collar is activated by normal motion. You can see this for yourself by holding the collar in your hand and shaking it a few times (certainly less than your dog would shake it by running across the yard). It will shock you with just a few shakes. Go with a more expensive collar (the innotek one worked great). My dog was terrified to move when she had this collar on because it is triggered by normal motion, NOT just barking.
