We might have to try the can of coins thing. I have been giving Agnes time outs in her crate when she starts getting bitey or barking at me. I know we're not stopped to use ta crate as "punishment" but it seems to be at least a little helpful and she still loves her crate because she'll go in on her own to nap. Biting means you have to sit alone for a few minutes and think about what you've done. Haha
