Stone fruits — peaches, cherries, plums, and nectarines — all share the same basic safety profile for dogs: the fruit flesh is generally safe in small amounts, but the pits are where the real risk is, and it's more serious than most people realize.
Why the pits are the actual danger
Stone fruit pits contain amygdalin, a compound that releases cyanide when metabolized. A dog would typically need to chew and crack open the pit (not just swallow one whole) to release a meaningful amount, but repeated exposure or a dog that likes to crunch pits is a real risk. On top of the toxicity concern, pits are also a straightforward choking and intestinal blockage hazard, regardless of the cyanide issue — which makes them dangerous even setting toxicity aside.
Can dogs eat peaches?
Yes, peach flesh in small amounts is fine for most dogs — remove the pit entirely, and the skin can stay on if washed well, though some dogs handle it better peeled. Canned peaches in syrup should be avoided due to added sugar; fresh is the better choice.
Can dogs eat cherries?
The flesh is technically non-toxic, but cherries are the trickiest of this group specifically because of the "without pits" concern people search for — cherry pits are small enough to be swallowed whole more easily than a peach pit, raising both choking and toxicity risk. Given the small edible flesh-to-pit ratio on a cherry, many vets suggest just skipping cherries altogether rather than trying to carefully pit each one.
Can dogs eat plums?
Same rule — flesh in small amounts is fine, pit removed entirely. Plum pits are also linked to intestinal obstruction reports in dogs beyond just the cyanide concern, so treat them with the same caution as peach pits.
Can dogs eat nectarines?
Nectarines are essentially a fuzz-free peach, and the same guidance applies directly: flesh in moderation, pit fully removed.
How much stone fruit is safe?
Treat all of these as occasional treats — a few small pieces, not a regular snack. The sugar content is also worth keeping in mind for dogs with weight or diabetes concerns.
What to do if your dog swallows a pit
Monitor for signs of an intestinal blockage — vomiting, not eating, straining or inability to pass stool, lethargy — and contact your vet if any of these appear. If you know your dog cracked open and chewed a pit (not just swallowed it whole), contact your vet regardless of symptoms, given the cyanide concern.
If your dog got into grapes instead, that's a different and more urgent concern — see our grapes and raisins guide for that specific danger.
