What Happens to Dogs If They Eat Chocolate? 

If you’re a pet owner, you know our furry companions are sometimes too curious for their own good, leading them to eat things they shouldn’t. Sometimes, that means substances or foods that are dangerous for pet consumption, such as chocolate. While we love to indulge in the sweet treat ourselves, chocolate is unfortunately toxic to dogs. But do you know exactly what makes chocolate deadly for dogs or the most dangerous type? Below, we will dive into canine chocolate toxicity and uncover the real impacts different types can have on our four-legged friends. By understanding the risks of chocolate toxicity, we’ll gain valuable insight for preventing health scares and keeping our pets safe from this enticing but lethal human food. 

From Delight to Disaster: The Hidden Dangers of Chocolate for Dogs 

The toxicity of chocolate, which can be severe and common in dogs, stems from the presence of stimulants like theobromine and caffeine. These compounds negatively impact dogs due to not having the ability to metabolize them efficiently, leading to a buildup in their system and the development of harmful symptoms. The darker the chocolate, the more harmful it may be because it contains higher levels of theobromine compared to white or milk chocolate. On the other hand, white and milk chocolates are rich in fat and sugar, which can cause stomach upset, vomiting, and diarrhea in dogs if consumed in large quantities. It is crucial to seek treatment if your dog has ingested a significant amount of chocolate to prevent potential long-term damage. 

Clinical Signs of Chocolate Toxicity 

The symptoms of chocolate poisoning are directly related to the type and amount of chocolate consumed. Monitor your dog closely for any clinical signs of poisoning. Common signs to watch out for include: 

  • Tremors in the muscles and limbs 
  • Seizures 
  • Irregular heartbeats 
  • Agitation/restlessness 
  • Increased heart rate 


If you suspect that your dog has ingested chocolate, it is crucial to take immediate action by contacting your veterinarian and Pet Poison Helpline at (855) 764-7661. Bring your dog to the veterinary clinic right away so that the veterinarian can evaluate the situation and decide on the appropriate treatment plan. Inducing vomiting and administering activated charcoal to bind the toxins may be necessary. Additional supportive treatments such as IV fluids and anti-diarrhea medications may also be administered. Do not hesitate to reach out to Pet Poison Helpline if you have any further inquiries about chocolate toxicity in pets.
