Yes she has!
When you compare her to a normal SS chestnut she is darker (similair to a normal SstyS chestnut) so she has DP. A hetero DP horse looks like he/she should have at least one Ssty but doesn't have it (so like your gal she looks like a SSsty chestnut [one sty] but has none) , or that it looks like a SstySsty chestnut but only has one (like this girl for example (she has DP) (http://www.huntandjump.com/horse.php?horseid=3611869); look how she looks the same as this normal SstySsty chestnut:http://www.huntandjump.com/horse.php?horseid=3473519)
You can also tell by her mane, flaxen chestnuts with DP will get yellowish manes like she has! Congratulations on your DP girl! :)

The mane and tail tells you nothing with DP.

Oh, I read somewhere in the forums that yellowy manes with flaxen chestnuts indicated DP.. Let me see if I can find it..

Since Gael said it I kinda assumed it was correct, sorry if I gave you incorrect information Forestshadow!

But she is as dark as a SSsty mare (and has no Ssty herself [she is SS]) so that's why she is a DP carrier!
