A lot of people are against shock collars, however, I have seen first hand how well they can work for training purposes. I have a family friend who uses one on their dog and she has reached the point where he puts it on her and doesn't even actually turn it on because she knows what she has to behave when it is on. Investing in one of these is the best thing you can do when you are training a new dog. You can invest in two of these collars and a remote for just $42.99 or the one collar and remote for $39.99 from Amazon.
