We don't have a problem with people teasing the Filas, (lol) but I used to have problems with morons teasing my German Shepherds. We had a neighbor brat who used to throw things at Purdue and bark at him from the other side of the fence, knowing full well that Purdue wouldn't leave the yard. The kid was 10 years old - plenty old enough to know better. One evening we were out in our yard at the same time his mother was in the garden in their side yard that adjoined our back yard. He made a big deal out of showing off to his mother and acting afraid, then ran and climbed up a ladder leaning against their house. His mom made a nasty comment to my mom about how "poor little Michael is so afraid of your dog, he has to climb the ladder to feel safe!" My mom thoroughly enjoyed telling her that the first trick I ever taught him was to climb ladders.
It also didn't matter that her 45 pound dog routinely used our front yard for her personal toilet and had bitten our 10 pound, 14 year old terrier. (Of course, Purdue took care of THAT problem. No one was allowed to hurt Mickey! It was the only time I ever saw him try to hurt another animal.)
She really had to eat crow one day when her 9 month old baby crawled out in the road because her 13 year old daughter wasn't watching him. Purdue had a fit, barking and crying and ran out to the road and stood over the baby until I went out and picked him up out of the road. I was so angry I was shaking, and told her she needed to pay more attention, my dog could've been killed trying to save her baby. They left him alone after that! They didn't bother me much anymore, either, come to think of it. Oh, well, I was 16 years old and full of righteous, red-headed indignation. It probably was a bit much. (g)
It all makes you wonder what is wrong with these people, doesn't it?
