".....breeder and many others in my breed won't let you have one of their puppies if you plan to send them away to obedience or behavioral modification camp because it's just one big steaming pile of dung in regards to how it ends up for the most part. "<end quote from Eater>
One of the greatest and most loved, funniest dogs in our breed <Rott> we've known was an amazing SchH<Schutzhund> 3 male, who loved playing with Wubbas and logs, children and smashing watermelons. He literally dragged my prone 170 pound husband <who was engaging him with a Tuggie> down the driveway one day. He was a dog who EXUDED presence, friendliness and charisma but could be VERY VERY serious. We are forever honored to have met him and he is related to both of our girls.
