If the dog has eaten chocolate, this is very worrying for dog owners. But it’s important to stay calm. Chocolate can be very dangerous for dogs because it contains theobromine. This substance can cause poisoning in dogs.
Theobromine is broken down slowly by dogs. This means that it can accumulate in the animal’s body. The risk varies depending on how much chocolate the dog has eaten. Dark chocolate and cocoa powder are particularly dangerous. White chocolate contains little theobromine.
It is very important to act quickly and wisely. This way you can protect your dog’s health.
The symptoms of theobromine poisoning can appear quickly. Sometimes the problem only becomes apparent after a few hours. The symptoms can range from diarrhea and vomiting to severe convulsions.
If you think your dog has eaten chocolate, you should go to the vet immediately. This can prevent many problems.

Why chocolate is dangerous for dogs
Chocolate is very dangerous for dogs. This is due to theobromine, a substance in the cocoa bean. This substance can poison dogs.
The effect of theobromine on the dog’s organism
Theobromine affects the nervous system and heartbeat of dogs. It can lead to diarrhea, vomiting and thirst. Too much can lead to convulsions and impaired consciousness.
The toxicity of chocolate for dogs is high. Even small amounts can be dangerous.
Different theobromine contents in chocolate varieties
The cocoa content determines how much theobromine is in the chocolate:
| Type of chocolate | Theobromine content per gram |
|---|---|
| White chocolate | Negligible |
| Milk chocolate | Approx. 2.0 mg |
| Dark chocolate (60%+ cocoa) | 14-26 mg |
Critical amounts according to body weight
Dogs can be poisoned by 20 mg theobromine per kg body weight. A 10 kg dog can be poisoned by 10 g of dark chocolate. That is a small piece of a 100 g bar.
The darker the chocolate, the more dangerous it is for dogs. If you suspect that your dog has eaten chocolate, you should consult a vet immediately. This will help you avoid serious consequences.
Dog has eaten chocolate: First signs of poisoning
If a dog eats chocolate, you need to act quickly. The first symptoms usually appear within 2 to 4 hours. Sometimes it takes longer.
Time course of the symptoms
The first signs often appear after just a few hours. It is important to observe the dog closely for the first 6-12 hours. Even if you do not see any immediate symptoms, you should keep an eye on your dog for at least 24 hours.
Physical reactions and warning signals
To recognize whether a dog is poisoned, you should look out for the following signs:
- Vomiting and diarrhea
- Increased thirst and urination
- Restlessness and trembling
- Panting and rapid breathing
- Palpitations or irregular heartbeat
- Muscle cramps or twitching

Special risks for puppies
Puppies are particularly at risk because of their small body weight. Even small amounts of chocolate can cause serious poisoning. The symptoms often occur more quickly and more severely in puppies than in older dogs.
| Theobromine dose | Effects on the dog |
|---|---|
| 20 mg/kg body weight | First signs of intoxication |
| 60 mg/kg body weight | Severe symptoms (convulsions, collapse) |
| 150-300 mg/kg body weight | Acute danger to life |
If chocolate poisoning is suspected, a vet should be consulted immediately. The sooner treatment begins, the better the chances of a full recovery.
Emergency measures and veterinary treatment
If you think your dog has eaten chocolate, you need to act quickly. Call a vet immediately. Explain to him what is happening and do what he tells you.
The vet can do various things to help your dog:
- Inducing vomiting

- Administering activated charcoal
- Giving infusions
In severe cases, your dog may need more help. The vet will monitor the situation closely and take action.

Important: Let the vet administer first aid. Do not try to induce vomiting yourself. This can be dangerous. A vet emergency means that you act immediately. The quicker the vet arrives, the better it is for your dog.
| Amount of chocolate | Risk level | Measures |
|---|---|---|
