I'll just call mine East Texas Boar Terriers!
I like that.
How can they determine what a pit bull is unless it has papers?
That's part of the problem, who can? Likely the one standing in front of it, looking at it. Odds are they won't know what they're looking at and will make an assumption.
It could very well be like in my town, an uneducated old pot bellied man that works for the city, and his phone rings when a stray dog shows up.
Being a city employee, his job is to drop what he's doing, go back to the barn and hook onto the little getter trailer they use.
He then shows up with a sack of snack or treats (likely yesterday's sack lunch leftovers) and attempts to coax it into the trailer.
By the time he's done dealing with this situation he's tired and angry, has missed his break or lunch, and could careless, he's taking the dog.
Right, wrong, no matter, you can see the troubles coming.
