Does it make sense, to carry some dry dog food in your bag or pocket, to distract an aggressive dog? Suppose you are walking in a street or park, and suddenly you are confronted with an unknown dog, that threatens to bite you? Could that dog be calmed down, by offering him some kibble?

If so, how should this technique be applied, and what type of dry dog food would be suitable? Do you have personal experience with this approach? Or do you know a website that offers any information about this idea?
