My big permanent blind on river has a long time beaver hutch about 10' from boat blind. Beavers generally swim thru decoys mornings we,re in blind and dive under dog platform to get to hutch. My older lab, now 12 would sit in dog door and watch them swim in & dive about 5' from her nose. New C.L.F this year, just 11 months old now and a lot more wired than old dog. Kind of curious as to what her reaction to that close encounter will be.
