Aloof.
He isnt agressive by any means. but he is not going to run/walk/crawl on our walks, in a store, at the park to a stranger. At the park he will keep his distance, and survey if he feels the need too.I could have him on a 30 foot leash, out as far as he can go on a sidewalk,a nd if a stranger walked past, he would keep to one side and not even attempt to meet the stranger lol. No I have never tested this theroy on leash, but offleash have seen it many times.
In the house he is different. he is more intrested, which i assume is becuase now they are on his property. He will walk up sniff them out, get a pat or two and go lay down.
