Is Plum safe for dogs?
Prunus domestica
The plum tree is a fruit-bearing species in the rose family, known for its edible stone fruits. While the fruit flesh is generally safe, the stems, leaves, and seeds contain cyanogenic glycosides that can be harmful if ingested.

Safety status
What this means for your dog
Dogs are more likely than cats to crack a plum pit because of their stronger bite, which makes them the higher-risk pet for cyanide poisoning from this plant. The cyanogenic compounds live in the inner kernel, leaves, stems, and especially wilting material — not the ripe fruit's flesh.
What to watch for
Vomiting, diarrhea, and abdominal pain may come first; the cyanide signature follows — panting, rapid or labored breathing, brick-red gums, dilated pupils, weakness, and shock. Whole-pit ingestion can also cause GI obstruction.
Time window
Cyanide onset is minutes to about an hour after kernel ingestion; signs can progress within hours. Uncomplicated GI upset typically resolves in 24-48 hours.
When to call the vet
Call immediately if a pit was crushed or chewed open, or if leaves or wilting material were eaten. Any labored breathing, gum-color change, or collapse is a same-minute emergency. Whole-pit swallows warrant a same-day call for obstruction risk.

Common signs
Vomiting, diarrhea, abdominal pain, and potential respiratory distress.
Escalation note
The stems, leaves, and seeds are toxic due to the presence of cyanide precursors. If ingestion occurs, contact your veterinarian or an animal poison control center right away.

Questions about Plum
Are plum trees toxic to dogs?
Plum trees (Prunus domestica) are potentially toxic to dogs. The fruit flesh is generally safe, but the stems, leaves, and seeds contain cyanogenic glycosides — cyanide precursors — that can cause vomiting, diarrhea, abdominal pain, and potentially serious respiratory distress.
What part of a plum is dangerous to dogs?
The pit (seed), stems, and leaves are the dangerous parts, all containing cyanide precursors. The risk is highest when a pit is crushed or chewed open, releasing the toxic kernel inside; a whole swallowed pit is lower in cyanide risk but poses a GI obstruction hazard.
What are the signs of cyanide poisoning in a dog that ate plum pits or leaves?
Early signs include vomiting, diarrhea, and abdominal pain. The more serious cyanide signature follows within minutes to an hour of kernel ingestion: panting, rapid or labored breathing, brick-red gums, dilated pupils, weakness, and shock. Gum-color changes or labored breathing are same-minute emergencies.
What should I do if my dog ate part of a plum tree?
Call your vet or the ASPCA Animal Poison Control Center at (888) 426-4435 immediately. Call right away if the pit was crushed or chewed, or if leaves or wilting material were eaten. Cyanide onset can occur within minutes to an hour after kernel ingestion, so do not wait for symptoms to appear.
