I guess you don't have sharks where you live. A tradesman I had working for me last week told me a friend of his had a dog taken by a bull shark, in a river less than an hour north of me. He was pig hunting with the dog. The dog chased the pig into the river, the shark took the dog, not the pig. If it had been a pet dog, it would have made the news. Dusk and dawn, we stay away from the water.Deja loves the river too. Whenever dogs are playing in the river, large fish show up. I often throw dog treats onto the surface and it makes the fish jump at so the dogs see them. It's a lot of fun to see their reaction.
