Mine are the same way.
I've never seen them real agressive in fact, only heard from my x-wife that they would be super protective when I wasn't home.
And of course seen it on the to occasions where we have had nightly "visitors."
Sam'll turn into a werewolf when that happens.
I can just picture that Coyote.
"Nope, that big thing is stopping......................it is stopping................................SHIT it aint........RUUUUUUUUNNNNNNNNNNNNN!"
Be like running down a narrow street in Eastern Europe, chased by an Abrams M1.
Tank ain't a Rottweiler, Justin.
He is a mix.
Just like I'd never have a purebred German shepherd, I've had a bunch of dogs that were ´bout 50 % shepherd.
Completely different thing.
Also, I've never cut the ears half way off of one of mine, just to make them look even more like Nazi dogs.
I do teach them to heil, though.
