aikido only worked against hotdog, with slaw and chili along with some onions.
What I found that worked well with dogs are lemongrass and ginger. we asians don't have problem with dogs.
Saw a show "the dog whisperer" or something like that. It's amazing the amount of psychology in animal control. the guy talked about energy and extending and center and personal space. he said something along the line, that if the dog sensed your energy collapse as in fear, the dog attacked. so much like aikido. saw he control the aggression of a nasty dog with a tennis racket (no, he didn't send it to the moon!).
