Chocolate
Never give chocolate to your pets. Chocolate contains caffeine and theobromine, both of which are toxic to dogs and cats. These substances can negatively impact their central nervous system and may also harm the heart.

Chocolate contains two substances that are toxic to dogs and cats: caffeine and theobromine. Both of these chemicals can overstimulate the central nervous system and put dangerous stress on the heart. Because of this, you should never feed chocolate to pets under any circumstances.
Caffeine
Caffeine stimulates the central nervous system, which can cause anxiety, restlessness, sleep disturbances, and other behavioral issues in pets. It also affects heart rate and blood pressure, potentially increasing the risk of hypertension, irregular heartbeat, and heart disease.
Theobromine
Theobromine also overstimulates the central nervous system, leading to anxiety, hyperactivity, and insomnia. It affects the heart in similar ways. Cats, in particular, have very limited ability to break down theobromine, so they are at especially high risk of severe poisoningeven from small amounts.
Symptoms of Chocolate Poisoning
Symptoms usually begin 6–12 hours after ingestion and can last for up to 72 hours. Common signs include:
- Vomiting
- Diarrhea
- Fever
- Difficulty breathing
- Seizures
- Rapid heartbeat
- Tremors or muscle twitching
What to Do If Your Pet Eats Chocolate
- Check the type and amount of chocolate consumed.
- If this is unknown or difficult to determine, visit a veterinarian immediately for evaluation and treatment.
The type of chocolate affects how dangerous it is. Dark chocolate and cocoa powder are the most toxic. For example, a small dog weighing about 3 kg (6.6 lbs) can reach a dangerous level of toxicity by ingesting just 6 teaspoons of dark chocolate.
Treatment at the Animal Hospital
Depending on the situation and severity, veterinarians may take the following steps:
- Inducing vomiting: If ingestion was recent, vomiting may be induced to remove the chocolate from the stomach.
- Fluid therapy: IV fluids may be administered to prevent dehydration and support kidney function.
- Oxygen therapy: If breathing problems occur, oxygen support may be provided to improve respiration.
- Medications: If the heart rate becomes irregular, medications can be given to help stabilize cardiac function.
Treatment may vary depending on your pet’s condition, the amount and type of chocolate consumed, and how quickly care is provided. Additional interventions may be necessary based on the veterinarian’s judgment.
Summary
Even small amounts of chocolate can cause serious poisoning in dogs and cats. Because of its toxic ingredients — caffeine and theobromine — chocolate should never be given to pets. If ingestion occurs, immediate veterinary care is essential for the best chance of recovery.
