Sounds like your neighbors are honest to god dog people, and the those are the best kind! (next to chicken people of course)
As to those people who dont believe the little trouble maker could do it all by himself, weeelllll,,,, let me tell you a story.... lol
I knew a lady who had a shephard mix. Well, he didnt like being left home alone. So one day he took it apon himself to damage thier back door in such a way that it opened and let him out, (wide french doors). then he carefully removed every cushion from the living room, to the back yard, where he destroyed it. THEN, he actually hauled the entire (remaining) sofa out the door, and ripped it to shreds. The neighbors called her at this point, when they came home, and saw him tugging it out the door inch by inch. They didnt dare go in the yard, but boy was he in trouble when she got home, and having been forwarned, snuck up on the house, and actually caught him head and shoulders deep in the back of the couch!
He earned a dog run, and a crate after that, and was never to repeat the episode, but boy his life was on a thin string for a long time! and he had no accomplices! he was one on one with that couch!
I love pits, they are a special breed, but give me my nice quiet lab mixes any day! or better yet, a flock of chickens!!
You have done well, with this situation, good neighbors are worth thier weight in Gold!
