This dog’s name is Mister. It’s spelled “Mr.” I took the photo of this guy cycling with his dog running on his fourth or fifth round of cycling back and forth.
BTW, this was in mid-May.
Man cycling with his dog in the forest around Banff
He was going back and forth with his dog, a couple hundred meters and turning around. He could have made a little circuit and go around the river, there are two bridges to make a little circle and the distance would have been the same. But no, he was just turning his bicycle around.
Later I saw the guy and asked him about his dog, then he went on his way.
