FAQs
My dog ate one chocolate chip — is that dangerous?
One chocolate chip contains about 0.2 oz of chocolate. For most medium to large dogs, this is a very low dose and unlikely to cause symptoms. However, small dogs can be more sensitive — use the calculator above and still contact your vet to be safe.
What happens if a dog eats dark chocolate?
Dark chocolate has 150 mg of theobromine per oz — over twice that of milk chocolate. Even small amounts can cause vomiting, diarrhea, elevated heart rate and tremors. At 60+ mg/kg, it can be fatal. Dark chocolate ingestion should always be treated as a potential emergency.
