I own a mixed-breed pittie and she is the sweetest, gentlest dog I have ever known.
I think any kind of vicious dog running around loose is fair game for the cops.
We had a real sweet Pit Bull next door. They kept her in the yard. Mr. GG2 used to play with her and give her treats when he was over there. I wasn’t afraid of the dog but never trusted it. My hairdresser has a Pit named Tank who runs and hides if anything happens. Scared of its own shadow. And I think when they are mixed the other breed mellows out the Pit Bull. I’m sure your dog is a fine dog.
But overall they are just IMO not good companion animals.
