What we do with our dogs is team work. You want to find dogs with personalities that you do well training; some are very stubborn (we call it hard) while some are very soft (cannot take much yelling). All dogs will have issues (genetic flaws) in their working ability; we find that there are some flaws we hate training on while there are other flaws that we don't mind training on and are good at training on. Since these flaws are genetic, they will always be there and training will be required to manage these flaws.
I suppose you could think about our dog handler teams like beach volleyball doubles; pairing two players can make a poor team (teammates always fighting with each other) or a great team (individuals with complementary skills that cover the other’s flaws).
Since we started competing with our dogs we have been watching a handler from Ontario running a line dogs she has been breeding (she breeds, trains, and competes with her own dogs); her dogs are consistently in the top 10 of North America. We believe her dogs have the personalities and working characteristics (styles) that we would do well working with and this male has characteristics we feel will complement those in our female.
