She is a pit bull terrier. Yea, she is so adorable but she will protect us. My late dog, Lilly was such a timid dog and very easy going with everyone. Whenever my next door neighbor comes by, she would growl and bark. She never did that with anyone else. Then she passed away. We got the pit bull and she has the same personality except for being timid (alpha female) but she is so friendly with everyone except for my next door neighbor. she starts growling and bark like an aggressive pit bull do if he stops by. So that means she is capable of protecting us by appearing aggressive when needed. lol
