I had a unsettling experience on Friday while grouse hunting on the Mt Evans SWA. My GSP starting acting birdy along a creek which was very thick with brush along the banks. She then started acting very nervous, backing up and growling while focusing intently on the thick brushy area. She barked a couple of times and backed completely away from the creek. I never saw or heard anything in the area of the creek. I assume it was a mountain lion or a bear. Have you guys ever experienced anything like this with your bird dogs?
