My dog ate chocolate: recognise symptoms and act immediately

Chocolate is easily left within reach around Halloween. It can be dangerous for dogs. The type, amount eaten, the dog's weight and prompt veterinary action are crucial.

Cocoa contains mainly theobromine and also caffeine. Dogs break these substances down much more slowly than humans. They can accumulate in the body and affect the nervous system, heart and circulation. The higher the cocoa content, the greater the risk generally is. Cocoa powder, baking cocoa and dark chocolate are therefore usually more dangerous than milk chocolate. White chocolate contains very little theobromine, but its high fat content can still contribute to digestive problems or inflammation of the pancreas.

There is no universally safe amount. Recipes, cocoa content and individual sensitivity vary. For a small dog, an amount may be problematic that might cause only mild symptoms in a large dog. A veterinary practice or clinic should therefore always assess the risk.

Call immediately and have the following information ready if possible:

If the amount is unclear, a cautious estimate is useful. Packaging remnants can help establish how much is missing. If the chocolate also contained raisins, macadamia nuts, alcohol or xylitol, be sure to mention this because there are additional risks.

The first signs may not appear until several hours later. They include:

Do not wait for symptoms. By the time symptoms become visible, a large amount of the substance may already have been absorbed.

Contact a veterinary practice or emergency vet immediately. Set off if advised to do so. Bring packaging and leftovers. Keep your dog calm and prevent any further ingestion.

Do not induce vomiting yourself. Salt, milk, oil, charcoal tablets or other home remedies can cause harm, delay treatment or lead to serious complications in a dog that is already drowsy. Whether emptying the stomach or using activated charcoal is appropriate depends on factors including timing, the product and the dog's condition, and must be decided by a vet.

Keep bowls of sweets out of reach, preferably in a closed cupboard. Explicitly ask guests and children not to give your dog anything. Remember coat pockets, backpacks, gift bags and waste bins too. Many dogs open packaging surprisingly quickly. Check the floor after handing out sweets so that no chocolate bars or chewing gum remain.

After poisoning, your vet decides when your dog can eat again and what is suitable. Choosing a bland diet or supplements yourself is not always appropriate. Once the acute situation is over and your vet has no objections, reviewing the whole diet can help coordinate main food, treats and daily portions.

Note: call a vet immediately if your dog may have eaten chocolate. Do not wait for symptoms or give home remedies.
