I just got a four month old blue-nose pitbull. She just showed up on our doorstep, and the owner told us we could have her or he will put her down. He could not take care of her. I have six kids ages 1 to 14. I need to know if she will stay calm and sweet as she is now, or should I worry. The only thing she does that bothers me is she will bark at my neighbors when they are outside. Not every neighbor, just certain ones. Other than that she is great. She licks all the time and snores louder than my husband. Is It normal to snore to?
