More: Moose passed on 3/3/2022. He spent every day of his life hiking the pattee/crazy canyon trails outside of Missoula, MT. Every day. This was one of his last hikes. In one week, he went front running up hills to being unable to lift his back end. He was diagnosed with acquired myasthenia gravis. He was such a good boy and is now in a place where he runs and chases deer all the time.
