Lychee

Lychees (also called lychees) sound harmless at first – exotic, sweet, juicy. For dogs, they are still not a good choice. The fruit flesh is not directly toxic in tiny amounts, but the pits and skin pose real risks. Add to that a hefty sugar content, and unripe lychees can even contain toxic substances. In short: It is best to keep lychees completely out of the dog’s reach.

Why are lychees problematic for dogs?

There are several reasons why lychees are not suitable for dogs – and unfortunately, they add up.

1. Unripe lychees can be toxic

Unripe fruits contain natural toxins that can manifest in various ways:

• Low blood sugar (hypoglycaemia): If blood sugar drops, weakness, trembling, seizures – and in the worst case even a coma – are threatened.
• Gastrointestinal problems: Unripe lychees irritate the digestive tract and can trigger vomiting or diarrhoea.

2. The pit is toxic

The pits of the lychee contain substances that can be harmful to dogs. If the dog chews or swallows a pit, there is a risk of poisoning. Moreover, lychee pits are hard enough to cause a bowel obstruction in smaller dogs – this is a medical emergency.

3. The skin is difficult to digest

The rough, leathery skin has no place in a dog’s stomach. It irritates the gastrointestinal tract and can lead to vomiting, diarrhoea or abdominal pain.

4. High sugar content

Lychees are naturally very high in sugar. If fed regularly or in large quantities, this promotes overweight, dental problems and, in the long term, even diabetes. Fruits high in sugar should generally remain an exception in dog food.

Can my dog eat the flesh of a lychee?

The flesh of a ripe lychee is not toxic for dogs – but that is no free pass. If at all, the following applies:

• Only ripe fruit: Unripe lychees can be toxic; this is not a myth. So make sure to check the ripeness.
• Remove pit and skin completely: Really completely. No “I think the pit is gone” – check.
• Less is more: Due to the high sugar content and possible stomach irritation, the flesh may only be considered as a tiny, occasional treat – not as a snack in between.

What to do if the dog has eaten a lychee with the pit?

If it happens – the dog has grabbed the whole lychee, pit included – there are two risks you need to keep in mind.

1. Poisoning from the pit

If the pit has been bitten or chewed, toxic substances can be released. Possible signs:

• Vomiting
• Diarrhoea
• Weakness or lethargy
• Breathing difficulties

2. Bowel obstruction from the pit

An undigested pit can also get stuck in the intestines, especially in small dogs. Watch out for:

• Constipation or difficulty passing stools
• Loss of appetite
• Abdominal pain or restlessness

Monitor your dog closely after the incident. If it shows vomiting, lethargy or shortness of breath, call the vet immediately or go straight there – better safe than sorry.

Better fruit options for dogs

If you want to occasionally give your dog a fruit, there are significantly better alternatives to choose from:

• Blueberries: Rich in antioxidants, good for heart health – and most dogs love them.
• Strawberries: Low in calories, high in vitamin C, good for skin and coat.
• Apples (without seeds): High in fibre and easy to digest – but be sure to remove the seeds.
• Watermelon (without seeds): Refreshing, low in calories and ideal on warm days.

These fruits are well tolerated, provide useful nutrients and come without the risk of poisoning that lychees carry.

Conclusion: Better skip lychees

Lychees do not belong in dog food. The risk profile – potential toxins, toxic pit, hard-to-digest skin, high sugar content – is simply too high for the effort to be worth it. If a small piece of flesh (without pit, without skin, ripe) does end up being eaten, that is probably not an emergency. But as a conscious snack choice, there are much better options. If your dog has eaten a lychee with the pit or shows signs of poisoning, do not hesitate: go straight to the vet.
