She sent me the pedigree of the Grade A dog, non-show lines, breeder was not a cavalier club member.
I doubt whether the breeder would have even known about SM four years ago. This was a lucky dog that inherited good genes from ancestors that were not from show lines.
I do not know the breeding of the affected dog.
Cavaliers......Tommy Tuppence 2000-2012 and a half share of Faith.
Japanese Chins.... Dandy, Benny, Bridgette and Hana.
