don't know what kind of dog I'm expected to have, but the truth is, I have a standard Poodle, a female. She is 'all dog'--wants to kill cats, birds, mice, rats, rabbits, and roll in cow **** after she digs a giant hole in the yard after dining on a nice bit of week-old mouldy cat ****.
But when I come home, the first thing she does (while she's shaking herself silly) is grab my hand and lead me into the house.
I don't think that is 'biting'...
That is just a dogs way of saying 'C'mon, dude, you've missed all the good stuff...welcome home!'
