Can dogs eat Lychee?
In small amounts, with care
In moderation - a small amount of peeled, de-stoned ripe lychee flesh is safe, but the stone and skin are hazards and unripe lychee can cause dangerously low blood sugar.

What happens
Ripe lychee flesh is not toxic to dogs and a small piece is harmless. Everything around it is the problem. The stone is large, hard and smooth, and it is a serious choking and obstruction risk - it is roughly the worst possible shape for a small dog to swallow. The skin is tough and indigestible. Most importantly, unripe lychee contains hypoglycin A, a compound that can cause a sharp drop in blood sugar; this has been linked to serious illness in humans eating unripe lychees on an empty stomach, and it is a genuine reason to keep unripe fruit away from dogs entirely. Ripe lychee is also very high in sugar, so it is a poor choice for a diabetic or overweight dog even when prepared properly.
How much is safe?
Half a peeled, de-stoned lychee for a small dog and one or two for a large one, occasionally. Given the preparation involved, blueberries do the same job with far less faff.
How to prepare it
Ripe fruit only, peeled completely, stone removed, flesh chopped. Never unripe lychee, never tinned lychee in syrup, and never leave a bowl of whole fruit where a dog can help itself.
Symptoms to watch for
Sugar in quantity causes loose stools. A swallowed stone shows as gagging, drooling, repeated vomiting, straining or a tender belly. Low blood sugar from unripe fruit would cause weakness, wobbliness, tremors or collapse and is urgent.
When to call the vet
Immediately if your dog has eaten unripe lychee or shows weakness or wobbliness. Also if a stone has been swallowed and vomiting, straining or gagging follows.

Common questions
What if my dog swallowed a lychee stone?
Ring your vet. The stone is large, hard and smooth, which makes it a real choking and obstruction risk, especially for a small dog. Watch for gagging, drooling, repeated vomiting, straining or a painful belly.
Why is unripe lychee dangerous?
It contains hypoglycin A, which can cause a sharp fall in blood sugar. That is why unripe lychee has been linked to serious illness in humans, and it is a good reason to keep green fruit away from dogs entirely.
Can dogs eat tinned lychees?
Better not. Tinned lychees sit in heavy syrup, which is a large amount of sugar for a dog. Fresh, ripe, peeled and de-stoned is the only version worth sharing.
