We purchased our first German Shepherd from Thinschmidt and couldn’t be more pleased. I researched several different breeders not only in California but across the U.S. I couldn’t be more pleased with Assertive K9 for the quality of dog we received as well as the overall process from first contact with them to bringing our dog home. I get compliments every day from people not only in his appearance but also in his temperament. I recommend using this family if you ever want to purchase a German Shepherd. You can truly see the difference between how our dog interacts with people and other animals verse other dogs who have not been bred for temperament.
