The Saginaw Valley Kennel Club will have their annual dog show, including a rally trial and obedience trials, April 6th - 8th at the Birch Run Expo Center. Rally competitions will be held on Friday. Judging starts at 11 AM. Obedience and conformation trials run Sat & Sun, judging starts at 9AM (or maybe 8).
Had to mention this, as I am a member of the club. There will also be a variety of vendors at the show. Progressive Kennel Club holds a show at the Expo Center a couple weekends after this show.
