and my dog is so small, that it doesnn't matter whether she barks, because she is as little as a cat, so she can't scare them away. And she never bites anybody! Never! :)
But carrying my cell phone and imitate to take picture is a good idea. Earlier I imitated to write the car number of those who stopped bye and didn't want to leave, this was also useful.
but this man are usually just alone there.
I don't know darude if kicking would be useful! :) I can kick, but they must be stronger than I am.
