How much lychee for your dog?
Most guides say "a few pieces". Enter your dog's weight and get the actual daily ceiling, worked out from lychee's calories and the 10%-of-daily-calories treat rule vets use.
Assumes a healthy, neutered adult at a stable weight, and that this is their only treat that day. Puppies, pregnant, very active or unwell pets need different amounts — ask your vet.
Why this verdict for dogs
A little peeled lychee flesh is non-toxic, but the seed is toxic and a choking hazard and the fruit is very sugary.
Lychee is a case where the fruit and the seed sit in completely different risk categories. The translucent flesh is a harmless novelty; the glossy brown stone inside it is not.
How much is safe?
A small amount of peeled, de-seeded flesh occasionally for a dog, and none for cats. The flesh is high in sugar, and lychee seeds contain compounds that interfere with blood-sugar regulation — the same family of compounds implicated in illness clusters linked to eating large amounts of unripe lychee. That risk sits with the seed and with unripe fruit, not with a piece of ripe flesh.
What happens if a dog eats too much?
Sugar-driven stomach upset and diarrhoea come first. The seed is the serious hazard: hard, smooth, and almost perfectly sized to obstruct a small dog's intestine, on top of the compounds it contains. Unripe fruit is worth avoiding entirely.
How to serve it safely
Peel off the rough skin, remove the stone completely, and offer one or two small pieces of ripe flesh. Never leave whole lychees where a pet can reach them — the skin and stone go down together with the flesh. Canned lychee in syrup is not suitable.

Frequently asked questions
My dog swallowed a lychee seed — is that an emergency?
Call your vet. The obstruction risk alone justifies it, particularly in a small dog, and the seed's compounds add a reason not to wait and see.
Can cats eat lychee?
There is no reason to offer it. Cats gain nothing from fruit sugar, and the seed hazard is worse in a smaller animal.
