Let me know if this link works. PEDIGREE RECORD © 2008, AQHA. All Rights Reserved.
I will add her to allbreed right now just in case the link doesn't work.
[Edit]: Hm, seems someone already put her in Allbreed but the sire's side doesn't match whats on record for AQHA. http://www.allbreedpedigree.com/dry+doc+smokin+peppy
It has her sire listed at Mr Peppy San. I'm going to try to edit it if it lets me. If it doesn't, I'll add another one.
