when Teddy was 1 yr old, he was attacked by a weimaraner who wasn't contained.. my brother took a few pics of that encounter by his bad mobile phone as he didn't feel the need to intervene.. this is the pic of that weimaraner,(I took this pic on a different day as this dog will be let lose most of the time) the weimaraner came running ferociously at teddy as if he'd engage in a fight!! Teddy was ready to take on the challenge!! The weimaraner approached teddy very angrily as teddy also gave a deep growl and was eager to attack, but I pulled teddy backwards.. The weim came too close but teddy was also extremely angry, and was vibrating with fury!! I mean even the leash was literally vibrating by his growl!! I pulled teddy further backwards while he was struggling to find a way to get that weim!! I mean teddy was eager to get him in a fight.. having been deterred by teddy's deep growl and dauntless will to really engage him in a battle, he backed away, while teddy was really steaming with fury!! The weim took a turn, and ran inside his house and went behind his car.. (you can see his leash in the pic) teddy triumphantly stood his ground and saw the weim escaping.. and he was calm in a few second and continued with walking.. ;)
