Continue reading to learn about how chocolate can affect dogs and what you can do to prevent any damage from being done.  

How Does Chocolate Affect Dogs? 

Chocolate poisoning is common and can be severe, but what exactly causes the toxicity? Chocolate contains stimulants, theobromine and caffeine, that negatively affect dogs. Dogs cannot effectively metabolize these compounds, leading to a buildup in their system resulting in harmful symptoms. The darker the chocolate is the more theobromine it contains. White and milk chocolate have high amounts of fat and sugar leading to stomach upset, vomiting, and diarrhea if consumed. If your dog has eaten a large amount of chocolate, they can experience damaging symptoms if treatment is not sought out.  

Symptoms of Chocolate Poisoning 

Chocolate is toxic to dogs and can cause a poisoning emergency if your pup eats it. Signs of poisoning typically appear within 6 to 12 hours after ingestion. The amount ingested and the kind of chocolate will determine the severity of the symptoms. Common signs of poisoning include: 

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


If you’re concerned that your dog has eaten chocolate, act immediately and contact your veterinarian and Pet Poison Helpline at (855) 764-7661.
