The flesh alone is low risk, but cherry pits, stems, and leaves contain a cyanide-releasing compound and are also a choking/obstruction hazard — treat whole cherries as unsafe.
Cherry pits, stems, and leaves contain amygdalin, which releases cyanide when metabolised — the concentration here is much higher than in apple or pear seeds, making accidental ingestion of pits a genuine concern, particularly if a dog chews and swallows several. The pit is also a significant choking and obstruction hazard on its own, regardless of the toxin.
| Timing | What to expect |
|---|---|
| Within hours | Vomiting, breathing difficulty, dilated pupils, bright red gums (signs of cyanide exposure) |
| Separately | Vomiting, straining, lethargy — signs of pit obstruction |
