I was also wondering what kind of dog it is- is he some kind of herding type? I have a border collie/black lab mix, and she chases & herds a lot of things she shouldn't like small kids if they are running around and small animals. I have had a hard time teaching her to not chase my cats, but she is good around them now. However, other cats that a are outside is a different story. I keep her on a leash most of the time now unless she is playing fetch, which she LOVES to do, and it seems to keep her out of trouble. I have also heard that agility training is really good for dogs that like to herd. Maybe it is worth a try for you, and it might be fun.
