Can you bond with a fish? Not sure about that. However, I think my dog Norman had. On several occasions from the porch I would see a pretty good size bass chasing bait fish up the side of the dike. Norman, on dry land of course, would be running almost side by side as the fish cornered dinner. Saw that more than one time. Never went to check it out. Didn’t think it was any of my business. Now here comes some tough times.
