Gorgeous dog on the bottom, well both are my friend. I have two boxers , I'm afraid they wont move unless the treat jar is disturbed. I hope if it comes down to it they will act.
Honestly after being thru training of three different Shepherds i found 99% of dogs won't do anything more then act tough. Now i am speaking strictly of taken care of dogs, and not the abused and unloved dogs thats a whole different issue and they will most of the time attack
They actually test our dogs in training in scenarios like one being will they attack a stranger who gets to close to the car if the owner aka me is unconscious in the driver seat or if they are in the car alone and someone gets in, another one is they test with me in MY home then they have me leave then the trainer tries to get in the house.
Thankfully not one of my three trained shepherds have fail the test they did in fact attack and the two above actually pack attack big time. My black one Tee she is the muscle, and niki the one above is the chasers and tracker. she's about 20 lbs smaller then my black one so she doesn't have the wight but she has the strength once she get ahold of you.
Thankfully people are more afraid of dogs then they are of guns so usually when someone gets frisky and they see the dog or dogs they seem to rethink their options
