I really don't see rottweiler, I still think the coloring comes more likely from black and tan coonhound, maybe dobie, I'd think that over rottie. One of my old co-workers had a black and tan and she reminds me of Ki, the way she barks, holds her tail, etc. as well as the "speckled" kind of tan/black fur she has on her belly, behind her ears, etc. (you know what I'm talking about. ) As to what else I have no idea, some smaller breed (she really is a lot smaller than she looks in pictures!), most likely she's a mix bred with a mix who knows.....all I know is she is 100% adorable.
