German shepherd lunged at me right in the Randolph East parking lot. It was perfectly calm and normal till it got right in front of me, then instantly snarled and jumped.
When approached by a loose dog on the trail, I yell "BAD DOG" regardless of it's behavior. It makes it clear to the owner that I am not okay with their dog. They often follow up with, "don't worry, he's friendly" to which I reply, "okay, I'm not". I've never had to do, but I would not hesitate to stab a dog with a trekking pole if it was aggressive. "BAD DOG" has always worked for me
Psyculman left us hanging in his hammock with that snarler......
