Dog Chocolate Toxicity Meter

The calculator will tell you how much theobromine and caffeine your dog ingested and what types of symptoms to expect. The calculator will also tell you whether an emergency visit to the veterinarian is recommended.

Chocolate contains two substances that are toxic to dogs: theobromine and caffeine. Dogs metabolize these items much slower than people do. Both theobromine and caffeine are stimulants to the central nervous system. If too much chocolate is ingested then the increased stimulus to the central nervous system can cause an increase in blood pressure and irregular heart rhythms and possibly even death!

Not sure how much chocolate your dog ate?

If the packaging of the chocolate is still around, you should be able to read how many ounces or grams of chocolate are in the product. If not, here are some guidelines:

• A milk chocolate Hershey’s Bar contains 1.5 oz (43g) of chocolate.
• A regular Toblerone Bar contains 3.5 oz (100g) of chocolate.
• A giant Toblerone Bar contains 14 oz (397g) of chocolate.
• A single Hershey’s Kiss contains 0.2 oz (5.7g) of chocolate.
