If the JH was never tested by the owners any further due to funds or time, I would look at her pedigree. I've seen pedigrees where mom didn't have a title but yet produced some FC offspring.Genetically speaking even if the dams are littermates they will bring a different percentage of the sire and dam genetics to the table. However, training could be a factor and the JH could actually be the better dog. You know may or may not know if the JH had the opportunity to be exposed to good training. The title will increase the value some and if she was a FC/AFC it would be even higher.
