CM: Dogs are predators, so it's natural for them to see a movement, such as bait whizzing by, and want to chase after it. But dogs can be conditioned out of this behavior. Begin in a park or another safe environment away from the water, and use your pole without the hook. Begin the activity by exercising your dog until he's very tired. Then, move the pole a little. If your dog doesn't move, reward him with a treat or affection. Then, move the pole a little more. Again, reward your dog for remaining calm and submissive. Continue the exercise until you can cast the line without a reaction from your dog.
