Blue nose American bully mixed with pit-bull he is gray but he has light brown Tri color patches over his back area and a couple of more places to. He has had his parvovirus shot already at 7 weeks. He’s a puppy so he is still learning i had him since birth. From what I’ve seen he’s not aggressive around any other dog no matter the size, like I said he is still learning so we are still potty training him but he is a great puppy.
