No — dangerous
No. Chocolate is one of the most common causes of poisoning in dogs. It contains theobromine, which dogs cannot break down properly — and the darker the chocolate, the more dangerous it is.
Theobromine and caffeine in chocolate overstimulate a dog’s heart and nervous system for up to 72 hours, because dogs metabolise these compounds 3–4 times slower than humans. Dark and baking chocolate contain 5–10× more theobromine than milk chocolate, so even small amounts of dark chocolate can poison a medium-sized dog. White chocolate contains almost no theobromine but is still a fatty, sugary food that can trigger stomach upset or pancreatitis.
There is no safe amount worth risking. Mild signs can start around 20 mg of theobromine per kg of body weight — that’s roughly 60 g of milk chocolate for a 7 kg dog. If your dog ate chocolate, use our Chocolate Toxicity Calculator to estimate the risk, and call your vet — early treatment makes a big difference.
Dog-safe “chocolate” treats made with carob are sold in most pet shops and are completely theobromine-free. For a quick natural treat, most dogs love banana slices or blueberries.
