I'm really impressed with D.t. systems and their dog training collars. The collar I purchased for my dog has made a world of difference in her behavior. She used to be very disobedient and had a tendency to wander off, but now she listens to my commands and stays close to me. The customer service was also excellent, with quick response times and helpful advice. I highly recommend D.t. systems to all dog owners!
