I figured out what was causing the hack. Brissy is most playful first thing in the morning and then again in the evening. While observing her playing in her outdoor pen at night I noticed her rooting in the grass and dirt with her nose. I mean she was really going at it. I think she was getting dirt in her sinuses then wanting to hack it out. She figured it out herself because she stopped this behavior and the hack stopped too!! Yea!! Smart puppy!!
