I just wanted to say, it is so refreshing to see someone thinking about breeding, looking for a mentor, health checking, and working/proving their dog. Bravo, OP! Good luck to you! I really hope you have great success. Beautiful dog btw! I know some around here aren't crazy about people breeding "white gsds," it is def a topic for debate. But I am just happy to see someone that is willing to go the extra mile while considering breeding(health checks, mentors, titling, etc). Like I said, hope it all works out for you!!
