We've covered that to. I tell her to leave it (and she listens) when she is carrying the ball in the house ect (because she ends up breaking something )

I am going to try practicing it more with her though.

We rarely use the ball with her now but when another dog in the park has brought one she doesn't necesarily have the ball she just thinks its hers. She will start snarling when she sees the dog with the ball, How do I scold her in a situation like that?
