Quantity
One to two teaspoons of ground nutmeg can be toxic to a medium-sized dog. A whole nutmeg seed contains enough myristicin to cause serious symptoms in any dog.
Notes
The trace amount of nutmeg in a single cookie or slice of pie is generally not enough to cause toxicity in a larger dog. The danger is in concentrated exposure — dogs getting into the spice cabinet, chewing on whole nutmeg seeds, or eating multiple nutmeg-heavy baked goods. Mace (the outer covering of the nutmeg seed) contains the same toxic compound.
Negative Signs
* Disorientation and confusion
* Tremors and muscle twitching
* Elevated heart rate and blood pressure
* Abdominal pain and bloating
* Seizures in larger doses
* Dry mouth and excessive thirst
FAQ
Q: My dog ate a cookie with nutmeg in it. Is that dangerous?
A: A single cookie with a dash of nutmeg is probably fine for a medium or large dog. The concern is concentrated exposure — whole seeds, spice jars, or large quantities of nutmeg-heavy baked goods.
Alternatives
Cinnamon in very small amounts is a much safer spice if you're making dog treats at home. Most dogs enjoy the flavor and it's well tolerated in tiny doses.
Risks & Disclaimer
If your dog ate a significant amount of nutmeg (more than a pinch), call your vet. A whole nutmeg seed or a tablespoon of ground nutmeg is a veterinary emergency for most dogs. Symptoms can take several hours to appear and may last up to 48 hours.
