As far we know Alaska was this dog:

In this photo she partecipated to an expo' (we were there) and she wins CAC, i think she had a pedigree (or not?)
After that she disappear and a very strange female, named Alaska, was registered in Italy with (new?) RSR pedigree.
I call it a "fake pedigree", rules (broken) or not.
