Dog Chocolate Toxicity Calculator
Chocolate is toxic to dogs because of theobromine. This estimates the dose your dog may have ingested so you know how urgent a vet call is — but it never replaces one.
Theobromine content (approximate, per ounce): milk ~44 mg, dark ~140 mg, baking/unsweetened ~400 mg, white ~1 mg. Toxic threshold: ~100 mg/kg of body weight is considered toxic in most references; signs (vomiting, restlessness, elevated heart rate, seizures) can appear above ~20 mg/kg. Dose: mg ingested ÷ dog weight in kg = mg/kg. CRITICAL: theobromine varies by brand and recipe; this is a risk-screening tool only. Any chocolate ingestion in a dog warrants a call to your vet or Pet Poison Helpline (800-213-6680) with the exact type and amount — do not wait for symptoms.
FAQ
How much chocolate is toxic to a dog?
It depends on weight and chocolate type. Dark and baking chocolate are far more toxic than milk. A toxic dose is roughly 100 mg of theobromine per kg of dog weight — but ANY ingestion should prompt a vet call.
What are the signs of chocolate poisoning in dogs?
Vomiting, diarrhea, restlessness, increased heart rate, tremors, and in severe cases seizures. Signs usually appear within 6-12 hours. Call your vet immediately even before symptoms show.
Is white chocolate toxic to dogs?
White chocolate has almost no theobromine, so it's not typically toxic, but the fat and sugar can cause stomach upset or pancreatitis. Still call your vet if your dog ate a large amount.
