nutmeg

Toxic

Nutmeg's myristicin causes disorientation, agitation, tachycardia, hypertension and, in large doses, seizures. The reported threshold is about 5 g (roughly 1 tsp ground or 2-3 whole seeds); a sprinkle is not an emergency.

More about this food

The problem compound in nutmeg is myristicin, alongside elemicin and safrole. Together they act like a weak MAO inhibitor with anticholinergic-style central effects, producing disorientation and hallucination-like behavior, agitation, tachycardia, hypertension, dry mouth, abdominal pain and, at higher doses, tremors and seizures. Dose is the whole story here. The Pet Poison Helpline's position is that a pet would have to eat a very large amount to be affected, and the reported threshold of concern is around 5 g, roughly one teaspoon of ground nutmeg or two to three whole seeds. A dusting on food is therefore not an emergency. What is a different conversation entirely is a dog eating a measured baking quantity, tipping over and finishing a spice jar, or chewing whole seeds. In US homes the seasonal risk is pumpkin spice season: eggnog, pumpkin pie filling, spice blends and holiday baking all put nutmeg within reach in quantity. The timeline is the trap. Signs are delayed 3-8 hours after ingestion and can last up to 48 hours, so a dog that looks fine at bedtime can be disoriented before dawn. If the amount is unclear, call your veterinarian or the Pet Poison Helpline at 855-764-7661 (a consultation fee applies) right away to work out the dose against your dog's weight. Do not induce vomiting at home, and take the container with you so the remaining amount can be weighed. Cinnamon is not in the same hazard class; in culinary amounts it mostly causes oral and GI irritation.

Frequently asked questions

My dog licked nutmeg off a slice of pie. Do I need the ER?
Probably not for a dusting. The Pet Poison Helpline says a pet would need a very large amount, with about 5 g (roughly a teaspoon of ground nutmeg) cited as the concerning threshold. Call for advice if the amount is unclear or your dog is small.
She ate it a couple of hours ago and seems normal.
That is expected and not reassuring yet. Nutmeg signs are delayed 3-8 hours and can last up to 48 hours, so the overnight window is the one that matters. Call your vet or 855-764-7661 now to set up what to watch for and when.
What about cinnamon in holiday baking?
Cinnamon is a much lower-grade hazard than nutmeg. At culinary amounts it mainly causes oral and GI irritation rather than the myristicin-driven central effects. Large ingestions or inhaled powder are still worth a call to your vet.
