When I wouldn't give him the keys to my car he would walk miles to the park whenever he got loose.
But the mind blower is he would viciously charge any dogs in sight. He charged three huskies, Saint Bernard, anything, any number. Scared the daylights out of me. Scared the hell out of the other dogs!
They are terriors which are real dogs, they have no fear.
Of course, at their size that isn't a plus.
My dog pulls me to see other dogs, but if he sees the dog is acting weird, he doesn't go near it realizing he could get hurt due to his small size.
As I walk down the street, he knows the homes of all his dog friends and tries to take me up the path of these houses to ring the door bell.
This is by far the most social animal I have had, very intelligent, and it acknowledges every human or pet it comes by.
He would let me know if he heard people messing about the neighborhood. No terrorists could sneak by him.
