If your pet has eaten chocolate and you know the quantity and the type of chocolate (cocoa percentage - e.g. 70% dark chocolate), please refer to the below calculator. The calculator will tell you how much theobromine and caffeine your pet has ingested, what symptoms to expect and whether an emergency vet visit is required.
The calculator is a guide only. If you are concerned your pet has ingested chocolate of any form, please seek veterinary advice as soon as possible.
