🚫 NO EATING – LYCHEE IS DANGEROUS FOR DOGS
Lychee (litchi) can be toxic to dogs, especially when the fruit is immature. The flesh and seeds contain natural toxins that interfere with vital metabolic processes.
🧪 Why Lychee Is Harmful
☠️ Toxic Compounds in Lychee
- Hypoglycin A (also found in ackee fruit)
- MCPG (methylenecyclopropylglycine)
These substances disrupt fat metabolism and energy production in dogs.
⚙️ How Lychee Toxins Affect a Dog’s Body
- ❌ Inhibit CoA (coenzyme A) and carnitine function.
- 🔁 Disrupt gluconeogenesis (synthesis of glucose) and fatty acid metabolism.
- 📉 Result in severe hypoglycaemia (dangerously low blood sugar) and metabolic acidosis.
⚠️ Without prompt treatment, these effects can be life‑threatening.
🩺 Symptoms of Lychee Poisoning
Symptoms may appear several hours after ingestion and can progress rapidly.
| Symptom | Description |
|---|---|
| 🤮 Vomiting | Common early sign |
| 💩 Diarrhoea | Often watery |
| 🤢 Abdominal discomfort | Whining, hunched posture |
| 😴 Lethargy / drowsiness | Unusual tiredness |
| 🫨 Convulsions (seizures) | Neurological involvement |
| 🧠 Coma | Severe stage |
| ⚰️ Death | From hypoglycaemic encephalopathy (brain damage due to low blood sugar) |
⏰ Time is critical – severe cases can be fatal within hours.
🍬 Additional Risk – High Sugar Content
Even if hypoglycin poisoning does not occur, the very high sugar content of lychee can:
- 📈 Cause rapid blood sugar spikes.
- 🩸 Increase burden on the pancreas.
- 🧸 Contribute to obesity and pancreatitis with repeated feeding.
📊 Risk Summary Table
| Risk Factor | Why It’s Dangerous |
|---|---|
| ☠️ Hypoglycin A & MCPG | Disrupt fat metabolism, cause severe hypoglycaemia and acidosis. |
| 🍬 High sugar content | Pancreas strain, obesity, diabetes risk. |
| 🥝 Immature fruit | Higher concentration of toxins. |
🚨 What to Do If Your Dog Eats Lychee
- 🧐 Note how many fruits and whether they were ripe or unripe (immature are more toxic).
- 📞 Contact your veterinarian immediately – hypoglycin poisoning is an emergency.
- 🩺 Do not induce vomiting unless directed by a vet.
- 🏥 Expect emergency treatment – may include:
- Intravenous glucose to correct hypoglycaemia.
- Acidosis management.
- Supportive care (fluids, monitoring).
✅ Early treatment greatly improves the chance of survival.
🛡️ Prevention – The Only Safe Approach
| ❌ DO NOT | ✅ SAFE ALTERNATIVES |
|---|---|
| Feed lychee (any part) | Apple slices (no seeds) |
| Give lychee seeds or peel | Blueberries, strawberries |
| Assume “one fruit won’t hurt” | Carrots, cucumber slices |
🔒 Keep lychee fruits and lychee‑containing desserts out of your dog’s reach.
📝 Final Takeaway
| Question | Answer |
|---|---|
| Is lychee toxic to dogs? | ✅ Yes – contains hypoglycin A and MCPG. |
| Are ripe lychees safer? | 🟡 Less toxic than unripe, but still dangerous due to sugar and potential toxin content. |
| What is the most dangerous part? | ⚠️ The flesh (especially of unripe fruit) and seeds. |
| What should I do if my dog eats lychee? | 🚑 Call your vet immediately – hypoglycaemia can be fatal if untreated. |
📢 Remember: Lychee can cause severe hypoglycaemia and brain damage in dogs. Never feed it to your pet.
