Back in the ‘70’s, I had a wolf/dog whose mother was a long haired German Shepard and father was a Timber Wolf...
His name was “Smokey” and he was about 110 lbs. and solid black...Even with the size and ancestry, he was a big pussycat...
The smartest and greatest dog I have ever been privileged to have in my life was a German Shepard. Best dog breed EVER.
