She's absolutely gorgeous!! It's hard to tell simply from a picture, but she really looks like she could be all (or atleast mostly Toller). Her coat is a bit short, and she's a little heavy for the average female Toller but besides that, it's the only breed I can see. She looks pretty young to me, which could explain the shorter coat. I'd guess around 6-8 months old. She sure is a beautiful girl .
