Negative Positive
Title: Worthless
Review: This item was purcheased for the purpose of seeing if it did what it says it does, it does not. I am a Military Working Dog Trainer and we used this item on 20 K-9s ranging from Sheps, Mals, Labs and mixed breeds. The K-9s ranged from high drive to low drive and no drive at all. Everytime it was used not one dog was effected by it. Do not waste your money.
