Oh, I forgot about pinapple
i have heard this works well too, someone else will have to direct you on how much to give though. I can't get my cats to eat pineapple (lol) so I use Forbid powder (this is the only one I found that's safe for cats so it may be the safest one for small dogs too) Here are the active ingredients of "Forbid": Purified vegetable protein fraction and sodium glutamate. You can try the pineapple first though
