One of my dogs is a malamute mix, and though she doesn't act quite like that, she is horribly stubborn! She KNOWS what she's supposed to do, but she just gives me that "Make me" look and does exactly what she's not supposed to. Rotten sometimes.

How vocal is yours? My dog is so vocal. She talks all the time. Not a bark, but that "baying-howl" kind of sound (I don't know what the vocalization is actually called). And all kinds of growls, groans, and other sounds.
