I'd say Border Collie mix (not sure with what though). I don't see any Toller at all in her (well, except for the orangey-brown colour) judging by body style, head shape and ear set. She does have similar markings to Tango's brother, Winter like Sarah already pointed out but a lot of dogs can have those same markings.

Here are some pics of Winter for marking comparison:




We'll have to see what she looks like when she gets older to make a better guess, pups are hard. Also, the other reason I say there isn't Toller in her is because fortunately there aren't a whole lot of people irresponsibly breeding Tollers. They're still considered a pretty rare breed right now.
