She is too cute!! I'm not sure about being part Rottie, she has
some of the colors, but that is all. Her tail is curled up, she may be part German Shephard; they often look like rotties as babies (color wise). Who knows, she may very well have Rottie in her...her ears do hang down like a rottie
.
Even if she isn't a rottie, raising her right is still VERY important!! You will find a ton of info here to help you with her!
