I mean really? It's a well known that the scent of a dog can spook fish. Dogs go out in the water (some species do) and splash around and make noise. Combined with their heavy scent and the strong sense of smell fish have, it will put fish off the bite most of the time. Not to mention the pain it is to other anglers who may not want to deal with a dog running up to them and barking or licking, etc. The other day, I saw a guy sitting on a rock with his rod laying next to him while he was tying up. Another guy's dog ran over to him and after a few seconds, got tangled up in the guy's line and when it tried to run away, it drug the guy's G Loomis rod about 8 feet over some big rocks. Aren't dogs supposed to be kept on a leash?
