The ASPCA lists plum as toxic to dogs — cyanogenic glycosides in the stems, leaves and stone. The stone is also a well-sized intestinal obstruction, and prunes add a laxative effect on top.
Don't feed it. If your dog has already eaten some, call your vet or poison control with the amount and the timing and follow their advice.
Never induce vomiting and never give any medicine unless a vet tells you to — it can do more damage than the poison. What we will and won't tell you.
Can cats eat plums? — Don't feed it to cats either.
No — plums should not be given to dogs. If yours has already eaten some, call your vet. The ASPCA lists plum as toxic to dogs — cyanogenic glycosides in the stems, leaves and stone. The stone is also a well-sized intestinal obstruction, and prunes add a laxative effect on top.
Watch for: Bright red gums; Dilated pupils; Panting or labored breathing; Collapse or shock; Or, if the stone is stuck: repeated vomiting, no appetite, a painful belly. Some signs lag by a day — call, don't wait.
More than a taste can cause real illness, and the risk rises with the amount and with a smaller pet. The safe amount is none — if your dog has had more, call your vet.
