I agree with eve. Although you may have some bad habits you,ll need to train her out of. Which isn't a problem providing the ppl around you stick to the new rules.
My dad always let's dexter get away with throwing the ball at him rather than putting it in his hand. I just about get him out the habit and then I'll have to vist my parents for something.

I've tried explaining and he says I'm being fussy

but my parents are providing free dog sitting so I can't complain too much.
Clover who I taught correctly from the beginning always delivers to everyone's hand

but I'd learnt a lot of lessons by the time I got her and we got things right from the outset.
Good luck
