Hello Sheena, I directed the hogwash statement at the need for Laura to see Cathy's dogs pedigree's(and clearances) in order to solve the problem of heart disease in the Cavalier. Now if Laura would like to see Cathy's pedigree's in order to help her own breeding program..I could understand that... Merry Christmas.
