If you want both a stopped and a running contact how do you train it? I have trained a stopped contact before and I have a dog who is small and training a running contact was not an issue because she doesn't jump over the yellow. But what if you want the choice to use both with the same dog? Also, what if I want a running A-frame but always a stopped dog-walk? Any special issues I'd run into there?
Here is a great example of a dog with both a stopped and running contact.
