What would your GSD do if someone walked in unannounced at night?
What would you say is a "normal" reaction, from a balanced dog, in the following scenario?
You and your family are in your basement, sound-proofed home theater.
Your dog is loose, and resting in his crate, upstairs.
A close relative (doesn't know the dog) sees your vehicles in your driveway, assumes you're home, rings the bell, and walks right into your home.
Would your dog attack and / or bite?
Would it just bark and do nothing more?
Would it do nothing?
I'd like to know what your dog would do?
What would you consider "appropriate?
