Frequently Asked Questions

How accurate is the chocolate calculator?

It estimates theobromine dose using average cocoa content. Individual products vary — always phone your vet or Animal PoisonLine with the wrapper details.

What if the calculator says low risk?

Still call your vet. Small dogs, combined ingestion, or dark chocolate can be more dangerous than the estimate suggests.
