I know this is an old thread but I've housed/borrowed Geronimo while getting him bred to a gyp my ex-partner owned. Geronimo is off of Max. I have 2 males around off of Geronimo that don't really lack anything. Both are really smart have great ability and they're both from 2 different breedings. I know of a Champion and some other winners he's thrown also. I love the Midnight crosses I have and have seen. I know Geronimo's original owner and was said the dog had passed recently. But can anyone point me in the right direction of working Midnight blood or a proven stud? I would be more than greatful to breed to and/or work the blood in a more pure form. Much appreciated for any help. I'm in the tri-state area.
