Cocoa powder
ToxicThe most concentrated methylxanthine source in a typical kitchen at 28.5 mg/g — about 12x milk chocolate. A 22 lb (10 kg) dog hits the first-signs threshold on only 7 g, roughly one tablespoon.

More about this food
Cocoa powder carries 28.5 mg of methylxanthines per gram (807 mg per ounce), roughly twelve times milk chocolate and higher than any other chocolate product likely to be in a US kitchen. Related products in the same family: baking chocolate at 15.5 mg/g, and cocoa bean hulls sold as garden mulch at 9 mg/g. Cocoa mulch is a recognized ingestion source, not a theoretical one — dogs eat it off the flower beds.
The thresholds are the same as for any chocolate: about 20 mg/kg for vomiting and diarrhea, 40-50 mg/kg for tachycardia and arrhythmias, and 60 mg/kg or above for tremors, hyperthermia and seizures. Concentration is what changes the picture. For a 22 lb (10 kg) dog, 20 mg/kg means 200 mg of methylxanthines, which is only 7 g of cocoa powder — about one tablespoon. Twenty-one grams puts the same dog at 60 mg/kg, in the seizure band. Where milk chocolate takes two full bars, here a dog licking spilled powder off the counter can reach a treatable-at-the-hospital dose.
Signs build over 6 to 12 hours, so an initially bright dog proves nothing. If baking supplies were out and the dog was alone in the kitchen, check for a torn bag or spilled powder before assuming nothing happened.
Call your veterinarian, an emergency clinic, or the ASPCA Animal Poison Control Center at (888) 426-4435 immediately, even if the amount is uncertain. Give the dog's weight, which product it was (cocoa powder, baking chocolate, or mulch), the estimated amount, and the time. Bring the container. Do not induce vomiting at home — whether to decontaminate depends on dose, elapsed time and the dog's condition, and doing it wrong risks aspiration pneumonia on top of the poisoning.
Frequently asked questions
- How much cocoa powder is dangerous for a dog?
- About 7 g, roughly a tablespoon, reaches the 20 mg/kg first-signs threshold for a 10 kg dog, and 21 g reaches the 60 mg/kg seizure band. Smaller dogs reach both on proportionally less.
- Is unsweetened baking cocoa worse than a candy bar?
- Much worse by weight. Cocoa powder is 28.5 mg/g of methylxanthines and baking chocolate 15.5 mg/g, against 2.3 mg/g for milk chocolate, so a tablespoon can outweigh a whole bar.
- My dog ate cocoa mulch from the garden.
- Cocoa bean hulls contain about 9 mg/g of methylxanthines and are a documented poisoning source. Estimate how much was eaten, call poison control or your vet, and switch to a different mulch.
