I grew up with Chows, we had a lot of them over the years never more than 2 at a time. They are also supposed to be vicious dogs… but we never had an issue. I tell you I lucked out with Layla. She is so well behaved, so well mannered, so obedient, so docile, and so loving. She has a jumping issue with new people and she likes to flee people a bit too much but I will take that. =) Pits are very beautiful and I think you will do well in getting one, especially given the fact that you are saving a life. It’s a shame your shelter doesn’t test their personality, they would probably adopt more dogs if they did that.
