My 30-pound dog ate a whole cup of pitted cherries I left out, is that too much?

Short answer

That amount of pitted cherry flesh is not toxic, but it's a lot of fruit for one meal. The main risk is a stomach upset from the sugar and fiber, leading to vomiting or diarrhea. Watch for a soft stomach or any changes in his next bowel movement. If he seems uncomfortable or vomits, call your regular vet for advice on settling his stomach.

The flesh is safe, but pits, stems and leaves contain cyanide compounds. Always pit them first.

Dogs and cats carry the same rating (Feed with care), so the notes below hold for either pet.

Cherries (pits removed) is not poisonous to dogs, but it is easy to over-feed. Rich fat, salt or seasoning can bring on vomiting or diarrhoea within a day, and repeated large portions are a recognised trigger for pancreatitis.

If it ate some before you noticed, watch for vomiting, diarrhoea, loss of appetite, unusual tiredness or a painful, swollen abdomen over the next 24 hours. A one-off small amount in a healthy adult usually passes with water and rest; repeated exposure, a puppy or kitten, a senior, or a pet with an ongoing illness is a reason to call your vet the same day.

Why these cautions matter

Stone-fruit pits and some seeds release cyanide when crushed, and quite apart from that they are a choking and blockage hazard.

Cherries (pits removed) can turn up now and then, but not as a daily habit: keep the rest of the day's food unchanged and watch the next walk and the stool that comes with it.
