Is there anything one can put on stuff to deter dogs from chewing on it?

My dog doesn’t seem to mind trying to take a bite out of pickles or raw onions if given the chance, so i’m wondering if there’s anything that dogs generally don’t like at all, that i can spray on some of my stuff that i don’t want her to chew to pieces. Cats are more finicky about things that they put into their mouths, but dogs…...not so easy! (well, they DO eat cat poop, so what else can one expect here, heh heh).
