No they are not from the same breeder, however there is a common ancestor in their pedigree at the great grandparent level and Tana's pedigree (Driftway) features quite strongly in Toby's Sire, Sire's grandparents and Sire's great parents. I adopted Toby from a Lab Rescue org and was fortunate that his pedigree papers had been provided to the Lab Rescue when his owners surrendered him when their marriage broke up, so I know his full pedigree. Tana I got from the breeder (Guy Spagnolo - Driftway) when he was 10 weeks old, so have his pedigree papers as well.
