If there is undisputed proof or an owner's admission I do not see an issue with changing a pedigree. My debate would be when the proof was found or when the admission was made.

My only issue with changing would be the "when' the information came forth (undisputable proof/owner admission). If I owned Buck in current time it would be greatly beneficial to know his actual parents as that may very well explain some things and better yet may help guide me in my breeding program with Buck. On the other hand if the information comes forward when Buck is mostly found in the fourth, fifth and sixth generation of my pedigrees it would be of little to no concern for me (if that makes sense).

I also think there will be a lot of apathy to the issue because it only affects a small percentage of pedigrees. Meaning, if I did not have Buck dogs, nor would I even choose to own Buck dogs, I could care less how Buck was bred.

On the grander scale, I think it is very important that truth and accuracy prevail, so for my one vote, it would be to show things in their most accurate setting. EWO
