Fast frantic digging= like a frantic tail wag. She'll do this on our legs (ow ow ow) when we walk in. Or, if she's in a playful mood, she'll dig on rugs.
wait, let me switch to first person...
Slow dab of the paw, one paw=Yo, hey, move the stuff off your lap. I require a place to lie down.
Faster poke of the paw=I'm cold and you're a clueless pain the ass, human. Let me under my blanket. Now.
Leaning over on her side and digging under the counters=I'm bored and have no idea what that is under there, but I'll eat it anyway. Care to give me a snack instead?
Reaching up and patting our face=You're kinda cute. Want to scratch behind my ears? Sure ya do.
Digging at Soozee's face=We're siblings and here's the proof: I'll annoy you until you go rawr and then everyone will say "HEY, LEAVE that POOR LIL DOG ALONE" I excel in sister torture.
She's much less crazed when strangers come over, although she still dislikes teenaged girls. And if a stranger tries to pat her she growls, moves away, and then when they straighten up, rears up on her hind legs and rests her front paws on their legs. Until they lean over again to pat her and she growls. Sounds obnoxious, but, really .... okay, it is obnoxious.
