I'm not sure suggesting a BC to someone looking for a second breed mostly as a performance prospect is all that bad. All breeds have their good and bad points. I think it's a stretch to say BCs are one of the most difficult dogs to train. Ever train a Basenji? Shar Pei?
I think it's a mistake for people to get a BC thinking the dog will be some sort of instant agility star that will make them look awesome in front of their peers. Not all BCs are great at agility. All will beed good training and handling to be all they could be. Not all people mesh well with them in terms of training or handling, not to mention every say life ( the sane xan ge said for any breed though). But obviously the breed has been proven over and over to have great potential to excel in sports.
All that said, I'm guessing Finkiemom has been around BCs enough to know if they interest her or not.
