Two Couple Pack , its where you run your 4 dogs being judged by 2 akc judges. They judge the pack work as well as time clock. Who ever gets best time out of 15 min. & has the best compatable pack wins . They demerite ya for hooken,geten out to side & mouthen out of place. You got to have 4 nice clean hounds that all are capable of runnen the front & each hound has to contribute. And speed is your option. I have finished 4 AKC Master Hunter { TCP FC}. & have 2 more that needs 1 more win finishing.
