COOL!! THANKS FOR THE PICS. Nice looking pitt! Never thought I would say that in a lifetime. That is quite a "buck" you have made for training.
That buck has been around the block many times. There are a number of tooth marks in it and there have been several dogs that have used it. I never, when I built it, would have guessed a Chessie or a Golden would ever use it. Let alone a Terrier (or mixed terrier) breed!
"Determining and applying the criteria for when and when not to use correction is the essence of the art of dog training. I make a distinction between a mistake and a lack of effort." - Mike Lardy - Volume I "After Collar Conditioning"
