I have four - 2 sl and two wl- I am considering rehoming my one year old all black Bomber son and my 3 year old black Drache Feld boy. Both of these dogs are very trained and well behaved but high drive. No issues.
The 3 year old also has protection training.
It kills me as I write this and my concern is how do they get to a nice home- not becoming kennel dogs like so many gsds. Here they live like people. This is not about money or trying to sell them.
