Everytime we come home, Lily (9 months) acts as though we've been gone for months. She squirms, wiggles, jumps, shakes, licks and generally acts as though she's having a seizure

She jumps until we pick her up but then is so hyperactive you can't even hold onto her! She's pretty calm otherwise. It's just when we come back...even if it's only been an hour. Does anyone else's pup do this? It's not really a problem...I'm just curious.
And here's another thing...she is a COMPULSIVE licker!!! I've never had or seen a dog that licks people as much as she does. She would lick our faces for hours if we'd allow it!
Do I have a neurotic baby???
