From "Ask the Pro - short bird success", p. 36 of latest Retriever News.
" To get a dog comfortably marking, and looking for, the short bird we should simplify the mark. There are many ways to teach a dog how to mark the short bird. One of the most basic principals is to throw the mark first as a single and then incorporate your test around this bird afterwards."
Is this repeating a mark? I guess I don't understand what he means by "incorporate your test around this bird afterwards".
