Please get into training with someone who is well versed in Working Dogs, Operant Conditioning and Classical Conditioning techniques.

Counter conditioning behaviors like this that have been rewarded (rewards don't have to be active and from you) takes time. Redirecting your dog once or twice doesn't cut it.

You need to gain a greater understanding of distractions, dog behavior and hone your own handling skills, as timing is EVERYTHING, especially with a reactive dog. Consistency from you is very important as well. It's most likely that this is simply reactive behavior than "protective" behavior as you are reading it.

If you have trouble researching trainers in your area, perhaps we can help you find a few to interview.

In the meantime, exercising him in your yard might be a better option than allowing this behavior to escalate further, and risking a mishap.
