Can dogs eat cherries?
The full picture
Cherries are one of those fruits where the risks outweigh the benefits. The pits, stems, and leaves contain cyanogenic glycosides — compounds that release cyanide when chewed or broken. One or two accidentally swallowed whole typically pass without issue, but several pits, or a chewed pit, present a real poisoning risk. Pits are also a classic intestinal blockage hazard for small and medium dogs. Maraschino cherries add the further problem of high sugar and sometimes artificial sweeteners. Safer sweet-fruit alternatives (blueberries, watermelon) make skipping cherries the sensible choice.
If your dog has just eaten cherries
Do this now
- If your dog ate only the flesh (no pits, stems, or leaves), watch for stomach upset but no immediate emergency
- If pits were eaten — especially chewed — call your vet; cyanide symptoms can develop within hours
- If a whole pit was swallowed, watch for signs of intestinal blockage (vomiting, reduced appetite, no poo) and call your vet
- Signs of cyanide toxicity include red gums, difficulty breathing, dilated pupils — emergency vet immediately
