I got the information from a Facebook board. The guy that owned the blue (don't know if he did the breeding or not) posted some info up and I've screen shorted it, deleted his name and uploaded it to Photobucket but Photobucket has got a virus on my phone and won't let me get the link. I must have tried two dozen times now
I remember you being friends with the man, but with 100% certainty I can say that (if the breeding of those blues I mentioned is true) Skull is a blue carrier
Genetically speaking, those dogs couldn't be blue if he is the real father and he didn't carry the dilution
