While we’re on the subject of canine comprehension, remember that "Far Side" cartoon where poor Ginger hears “Blah, blah, blah, Ginger blah blah blah"? Well, that's truer than you think. Remember, dogs think in a linear manner. Stringing a long line of words together requires a long thought process, something they are less skilled at than we are (Green Bay Packers fans notwithstanding). Consider developing a short training vocabulary. Keep out extraneous words. Think Hemingway, not Shakespeare. Leave the expansive narrative for that post-hunt campfire story. Your hunting buddies might be better at the long thought process than your dog, but I don't know your friends. Or your dog.
