Conflicting Information About Dog's Lineage?? Painters Daily Double - Page 1

Hello all,
   I've run into a little dilema. I'm researching the dogs from my chocolate Lab's pedigree and history and I found conflicting information about the ancestry. I'm confused...here on Pedigreedatabase, there is a dog listed as a female, but on huntinglabpedigree, it is listed as a male. Same name, same reg. I registered my dogs pedigree, some of the dogs I searched were already listed in this databse. Now I've run into a problem because I cannot add Painters Daily Double; same name, same reg #, same lineage, same everything, but as a different sex...? I've put links for this dog, his/her name is Painters Daily Double. If anyone can help, I'd greatly appreciate it. Thanks!

I thought this name looked familiar. I also have this dog in my dogs pedigree. On my AKC papers it is listed as a male so I check further and according to the OFA website "Painters Daily Double" was a male born on October 4th 1981. You can researched his OFA number and AKC number as well as progeny at www.offa.org hope this helps.
