We have a white GSD that's absolutely, unequivocally, without a doubt, the sweetest dog I've ever known in my life. She's the only dog we have that doesn't try to kill our dog-aggressive border collie.. She'll go over to say hi, wagging her whole body, and the BC always growls and bears teeth. Always. Every single time. Yet, the white GSD never gives up. In three years, she's never given up hope that one day the BC will decide she wants to be friends.
We've actually witnessed the GSD lick the BCs teeth before as she snarls and growls.. She tries so hard to make friends, it's just heartbreaking to see her rejected over and over again.
Sweetest.dog.ever.
