Lychee — Food safety facts
Feed with care · Dogs · full breakdown on the linked food page
Flesh only, and only a little — it is very high in sugar. The pit is a choking and obstruction hazard.
Dogs and cats carry the same rating (Feed with care), so the notes below hold for either pet.
Lychee 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
Added sugar brings empty calories, and over months that means weight gain and dental disease — both far harder to undo than to avoid.
Stone-fruit pits and some seeds release cyanide when crushed, and quite apart from that they are a choking and blockage hazard.
