Dogs can eat plums, but only in moderation and only if the pit is completely removed. The flesh of the plum is generally safe and can provide some vitamins and fiber, but the pits are toxic because they contain amygdalin, which can convert to hydrogen cyanide, a deadly poison for dogs. The pits also pose a choking hazard and can cause digestive damage or intestinal blockage. Additionally, plums are high in sugar, so feeding too much can lead to stomach upset, obesity, or diabetes in dogs. Dried plums (prunes) should be avoided altogether due to their high sugar content and potential toxins. If feeding plums to dogs, always remove pits and stems, and give only small amounts as an occasional treat.
