Can dogs eat nutmeg?

NO — Dogs should not eat nutmeg. Nutmeg contains myristicin, a psychoactive compound that can cause GI upset, hallucinations, seizures and increased heart rate. Emergency care may be needed.

Quick Safety Summary

• Verdict: NO — dogs should not eat nutmeg. It contains myristicin, a potentially toxic compound.
• Main hazards: gastrointestinal upset, central nervous system effects (disorientation, hallucination-like behavior, tremors, seizures), and cardiovascular effects (fast heart rate).
• Onset: usually within 1–6 hours; effects can last 24–48+ hours depending on dose.
• If your dog ate nutmeg: remove access, call your veterinarian or ASPCA Animal Poison Control at (888) 426-4435 immediately. Do not induce vomiting unless instructed.

Can dogs eat nutmeg? Short answer and safety verdict

NO — dogs should not eat nutmeg. Although nutmeg is a common kitchen spice and a small accidental lick may only cause minor stomach upset, nutmeg contains the compound myristicin which can produce serious neurologic and cardiac effects in dogs at low-to-moderate doses. For safety, avoid feeding any nutmeg or foods containing nutmeg to dogs.

What is in nutmeg that’s dangerous? Myristicin explained

Nutmeg (Myristica fragrans) contains essential oils and several bioactive compounds; the most clinically important is myristicin. Myristicin is a naturally occurring phenylpropene with mild psychoactive and anticholinergic properties. In overdose it can:

• Affect the central nervous system (CNS), causing disorientation, bizarre behavior that owners may describe as "hallucinations," agitation, tremors and seizures.
• Interfere with autonomic nervous system control, producing fast heart rate (tachycardia), dilation of pupils and elevated body temperature.
• Irritate the gastrointestinal tract, causing vomiting and diarrhea which can contribute to dehydration and further stress.

Signs of nutmeg/myristicin toxicity in dogs

Watch for a combination of gastrointestinal, neurologic and cardiovascular signs. Common symptoms include:

• Vomiting and diarrhea
• Lethargy or hyperactivity and agitation
• Disorientation, pacing, strange/staring behavior (owners may interpret as hallucinations)
• Ataxia (stumbling), tremors
• Seizures (generalized convulsions)
• Rapid heart rate (tachycardia) and possible arrhythmias
• Elevated body temperature, excessive panting
• Dilated pupils

Toxic dose: what amount is dangerous for dogs?

Exact toxic doses for nutmeg/myristicin in dogs are not precisely defined in the literature because nutmeg’s concentration of myristicin varies and published reports are mostly case-based. However:

• Human toxic reactions have been reported after ingestion of a few grams of ground nutmeg (several teaspoons).
• Veterinary case reports and toxicology resources indicate that ingestion of a few grams of nutmeg can produce systemic effects in dogs; this becomes especially risky in small dogs.

• Small dog (5 kg / 11 lb): ingestion of a pinch to a teaspoon (0.2–2 g) may be enough to cause GI or early neurologic signs; larger amounts proportionally increase risk.
• Medium dog (15 kg / 33 lb): ingestion of several grams (2–5 g) may cause signs; higher doses increase likelihood of neurologic effects.
• Large dog (30 kg / 66 lb): larger quantities (several grams to tens of grams) are more likely to cause systemic toxicity, but even a few teaspoons (several grams) could be problematic depending on sensitivity.

Nutritional context: is nutmeg ‘‘healthy’’ for dogs?

Nutmeg is not a nutritionally necessary or beneficial food for dogs. Typical nutrition for ground nutmeg (approximate per 1 teaspoon / ~2 g): ~10–12 kcal, negligible protein, small amounts of fat and carbohydrates, and trace micronutrients. These small caloric and nutrient contributions do not justify the risk of toxicity.

What to do if your dog ate nutmeg — emergency steps

Follow these steps immediately and treat nutmeg as a potential poisoning:

Emergency veterinary treatment commonly includes:

• Decontamination: activated charcoal may be given to bind remaining toxin in the gut if the dog presents early and is stable. Gastrointestinal decontamination (emesis) may be used if appropriate and recommended.
• Supportive care: intravenous fluids to prevent dehydration, temperature control, oxygen supplementation if needed.
• Symptom control: anticonvulsant medications (e.g., diazepam, midazolam) for seizures; sedatives for severe agitation; medications to control heart rate or arrhythmias if present.
• Monitoring: cardiac monitoring, bloodwork and observation for 24–48 hours or longer depending on severity.

Preventing nutmeg poisoning

• Do not add nutmeg or nutmeg-containing foods (e.g., holiday baked goods, eggnog, spice mixes) to your dog’s diet.
• Keep spice jars, baking ingredients and dishes containing nutmeg out of reach, especially during holidays when baking and spiced foods are common.
• Educate family and guests that nutmeg is unsafe for pets.

When might a tiny accidental lick be low risk?

A single tiny lick of a dish that contains only trace nutmeg (e.g., a stray lick from a cookie) will often cause no systemic toxicity and at most mild GI upset in many dogs. However, because some dogs are more sensitive and because myristicin concentration varies, any exposure should be judged by the amount eaten and the dog’s size; when in doubt, contact your vet or ASPCA Poison Control at (888) 426-4435.

Key Takeaways

• Nutmeg is potentially toxic to dogs because of myristicin — NO, don’t feed nutmeg to dogs.
• Symptoms include vomiting, diarrhea, disorientation/hallucination-like behavior, tremors, seizures and a fast heart rate.
• Exact toxic dose isn’t well-defined; ingestion of a few grams can cause symptoms, and small dogs are at higher risk.
• If ingestion occurs, call your vet and ASPCA Animal Poison Control at (888) 426-4435 immediately; don’t induce vomiting unless instructed.
• Prevent exposure by keeping spices and nutmeg-containing foods out of reach.
