Every dog is different. Individual allergies and sensitivities are common — always introduce new foods in small amounts and watch for adverse reactions. This site is for informational purposes only and is not veterinary advice. Always consult your vet.
The Full Picture
The flesh of a ripe plum is not toxic to dogs, but the pit makes plums dangerous. Like cherries and peaches, plum pits contain cyanide and are hard, sharp-edged objects that can cause choking, damage to the mouth and digestive tract, or intestinal obstruction. The roots, stems, and leaves of plum trees are also toxic. Given the difficulty of safely removing the pit and the risk if a dog gets hold of a whole plum, it is best to avoid plums and offer safer fruits such as blueberries or watermelon instead.
What You Should Know
Plums should be kept well away from dogs. If your dog has eaten plums, watch for symptoms such as vomiting, diarrhea, lethargy, or loss of appetite. In an emergency, contact your veterinarian or an animal poison helpline straight away.
