The pedigree shown for Tucker's Abbie is according to information which has been confirmed to me in conversations with Mr David Sanders of Aspenrare Kennels who owned Kotton, Kombat, Bishop etc. Current NKC and ABA pedigrees should show Abbie's breeding as described above, but some corrupted pedigrees may show Tundra as being out of Daguimol's Hammer and Blue Sky's Mamie.... this information is entirely inaccurate and David Sanders has no idea where this may have originated from and he has never used either of those two dogs in his breeding program.
