Well, I don’t know about most people with pitbulls, but my husband and I are both scientists, with Ph.D’s.He is a biologist; I am a statistician and a professor. We are lifetime dog owners and lovers. We got out first pitbull 4 years ago. She is the best dog we’ve ever had. Very people friendly. They are not a dog for everyone because of their energy. You need to be willing to spend time with them. I don’t think that willingness has much to do with IQ, however. And no, we don’t take her to the dog park because we don’t trust the other dogs!
