I think three days is a very short period of time to have bonded with an adult dog. I'm not sure I'd be willing to purchase an adult Pit Bull unless it was EXTREMELY sociable and not at all interested in "social climbing". Usually, but not always, the gamebred ones are like this. I'd also not be interested unless I was sure that it was properly socialized. In other words, I'd have to truly know the dog and witness it in various social situations.
