Wondering if anyone has tried the powders that you sprinkle on food to stop the dog from eating cat poop?

Here's the background. I have Piper (Yorkie), two Springer Spaniels and 4 cats. Piper and one of the Springers eat their own feces and the cats. I can pick up the dog feces in the yard and I've built a large crate around the cat litter box to keep the Springer out. I can't put the litter box up high because one of my cats is 15 and she can't jump. I don't want to put a shock collar on Piper and there is no way I can get 4 cats to eat pineapple and I don't even know if they should. And, the reviews on the automatic cat litter boxes aren't good. I've said all of this to let you know that I've explored many, many options. Thanks!
