Dogs are just like people in a lot of ways,
More like people in some ways than people
are.
"Mean" dogs are not tolerable in any circumstance.
Dangerous dogs are a different matter. If
these "guard" dogs are loose, then they are
not true guard dogs, who *KNOW* their boundries and will defend those boundries
with dedication not often seen in even couragous men. Sounds like they are just
plain ole mean dogs, as you said.
I don't know how sound this advice is, but it
has worked for me the few times I've used it
myself.
Do as the others say, First contact the owner, which you say you've done. Next it's animal control. That will usually resolve it. They will capture and destroy the dog if it is not kept under controll. , , Usually.
Since you know of the problem, you know to be armed with pepper spray, ammonia or something else.
Lacking those things,
You become the mean dog, a mean dog like the mean dog has never seen. The dog rushes you you rush the dog, (s)he barks, you scream!
You *must* belive only one thing, and belive it over all other things, to the point that nothing else matters, that you will eat this dogs heart for dinner.
This cannot be successfully faked. You might confuse a dog by "acting" mean, yelling and such, and this may have some effect. But you cannot lie to a dog. They are naive in this way, they don't understand fakery and bluffing, and they know the difference between playtime and worktime. Dogs understand true honesty, and if you honestly intend to eat that dogs heart for dinner, and the dog only intends to make you go away, they will get the picture.
I'm one of those kids who got mauled as a little one. My folks get me a dog right away to help offset the inevitable fear that comes from almost being a predators dinner. It helped I am sure, but it was about 10 years before I was once again cornered by a neighborhood shepard absolutely paralized with fear when something snapped and I decided to find out who was going to eat who.
I luckily had a swiss army knife.
That was dog1
There was another later on,
I am the third dog.
