Chocolate poisoning is a race against absorption, so treat any eaten chocolate as urgent even before symptoms appear. The darker and more concentrated the chocolate — cocoa powder and baking chocolate sit at the dangerous end, dark chocolate close behind — the more theobromine each gram carries, and it is the amount eaten against your dog's weight that decides how serious the call is. Phone your veterinarian or an emergency service straight away with four facts ready: your dog's weight, the type of chocolate, roughly how much is missing, and when it was eaten.
What Happens and What Not to Do
Do not try to make your dog sick at home unless a vet specifically instructs you — it can cause its own harm. Keep the packaging: the cocoa percentage helps the vet judge how serious the amount is. Signs of chocolate poisoning typically appear within 6–12 hours and include vomiting and diarrhoea, restlessness, panting, a racing heart, tremors, and in severe cases seizures; even a dog who looks fine after eating a significant amount needs the vet call, because early signs can escalate. Store chocolate like medicine afterwards: in closed containers, up high, and brief anyone who feeds the dog that it is never a treat.
If it was within the last couple of hours, vets can often induce vomiting safely at the clinic and give treatment that greatly reduces the risk — that window is why speed matters more than home remedies. If your regular vet is closed, go straight to the emergency service rather than waiting until morning for a known chocolate ingestion of any meaningful amount, and bring the packaging with you. This article is general information about a common emergency; the treatment decision for your dog can only be made by the vet who takes your call.
After the Scare: Notes That Help Next Time
Once your dog is safe, write down what happened while it is fresh: the product and its cocoa percentage, your best estimate of the amount, the time eaten, the time you called, and every symptom with the hour it appeared. That record turns a frightening evening into useful history — if there is ever a second incident, or a different emergency entirely, the clinic starts with facts instead of reconstruction. Note also where the chocolate was stored and who had access, then fix that gap the same day, because repeat ingestions usually come through the same open cupboard or low coffee table. Keep the weight and treatment notes from this scare in the Pet Passport on KinsLe, where health records, dates, and visit history stay together for the next appointment.
