Neighbor threatens me with his fighting dog, Dobermann.

Every time I meet my neighbor, I get scared. Especially when he's on the move with Doberman and in jumper boots.
When the cattle storm up the aisle and braid their teeth, I have real anxiety every time.
The neighbour doesn't know the obligation to use a leash.
Now there was a problem because of the parking lots and I have the impression the neighbour uses his dog consciously as an indirect means of pressure. In any case, nobody dares to contradict him at the tenants' meeting.
Can one do nothing there ?

The police said, as long as he does not bite ...

I mean, if he bites, it's already too late!
