Heck, even huskies can be aggressive. I rescued one girl who'd been abused for more than eight years. She didn't trust anyone. But she would walk up to people, pretty as can be, sniff their knees, and when the person reached down to pet her, she'd snap at them, no warning at all. She scared the heck out of me for a while, even. Could never let strangers near her, not even after we gained her trust.
But...what's this about the White House staff blaming the dog? They have the muzzle on Biden, don't they?
