I wouldn't expect a 5-month-old dog of any breed to be a deterrent. It would be like expecting a 6th-grade child to be a deterrent. I'd suggest watching some of our training material on raising a puppy that you want to be some type of working partner. The key is to teach him about the world, keeping in mind your goals.

I have a young German Shepherd male, I got him at 8 weeks and he's now 3. He's just now starting to really show some territorial behaviors at my house. I know his bloodlines mature slowly and the change in him over the last couple of months has been interesting.
