Ah okay, i might be thinking of pit bulls, are these the ones that have been made illegal? or at least i've seen lots of attacks in the news.

I personally wouldn't buy a dog unless from a breeder, and of course would view the parents temperament, but i know my MIL won't care about those things and is going to just view the puppy and go by how it is.

So i guess i just have to take the huge risk and hope they train it better than their cavalier (who still jumps on my toddler and is 5 years old).
