I have been using the dog training collars from D.t. systems for a while now and I have to say that they are the best in the market. The collars are easy to use, durable, and highly effective in training my dogs. The customer service is also excellent, always responsive and ready to assist. I highly recommend D.t. systems to any dog owner looking for reliable and efficient training tools.
