What You Need to Know

Longan is a small tropical fruit closely related to lychee and rambutan — all three are in the soapberry family and share similar safety profiles for dogs. The translucent white flesh without seed or skin is safe in small amounts. The seed however contains saponins — compounds that cause digestive upset and irritation — and must be removed completely before any dog access.

The sugar content of longan is very high — higher than most fruits at approximately 15g of sugar per 100g of flesh. This makes strict portion control essential, particularly for diabetic dogs or dogs prone to weight gain. A few small pieces of flesh is the appropriate amount — not a bowl full.

Longan is available fresh in Asian grocery stores during summer months and canned or frozen year round. Fresh longan has a papery brown shell that peels away easily revealing the flesh inside. Canned longan in syrup contains too much added sugar — always use fresh or frozen plain longan without syrup. Remove the seed and skin completely before serving.

Longan is sometimes called dragon eye fruit because the peeled fruit with its dark seed visible through the translucent flesh resembles an eyeball. It has a sweeter and less floral flavor than lychee making it more readily accepted by dogs. The same preparation rules as lychee apply — flesh only with seed completely removed in very small amounts.
