We got some sort of new collar that's supposed to train the dog not to bark. Whenever she barks (which is whenever she'd rather be tear-assing through the house, destroying everything in sight, than sitting quietly in her crate playing with her toys), it releases a burst of nontoxic lemon scent. The dog is supposed to dislike the lemon scent and learn not to bark.
I think my dog might like the smell of lemons.
