It was fun to have a few minutes to watch the way he closed off his nostrils before heading under the water, and he was fairly close and undisturbed by me. Last February, I was walking the dog past a dock and heard a funny noise. I saw this otter watching us, and sort of snorting at us. The dog was intrigued enough that I was afraid he’d jump in to play. I am still not sure if the otter didn’t want us to move out of his way (we were near a place where they have a trail across the road) or whether the otter was either scolding the dog or wanting him to play.
