Can Dogs Eat Peanut Butter Cups?

Peanut butter cups combine two separate risk factors into one small, appealingly sweet package: the chocolate coating carries the usual theobromine risk, made worse by the fact that dogs often find these treats particularly tempting and will eat several at once given the chance, while the peanut butter filling itself is a genuine additional concern if the brand used happens to be sweetened with xylitol, which some peanut butters increasingly are as a lower-sugar option. This combination means a dog that raids a box of peanut butter cups could be facing two serious toxins in the same mouthful, rather than the milder profile you might assume from a food that's mostly peanut butter. Because the chocolate content alone is already enough to justify urgent action, and there's no reliable way to know from the outside whether the peanut butter used was xylitol-sweetened, any known ingestion of peanut butter cups should go straight to your vet as an emergency rather than being monitored at home.
