When it comes to your dog eating chocolate, you may be concerned about the consequences at stake. Depending on the size of your dog, the type of chocolate consumed, and the amount there could be a real emergency. Chocolate poisoning in dogs is more common than you think and if treatment is delayed, it can be fatal. Below is everything you need to know if your dog ingested chocolate: 

Why Is Chocolate Dangerous for Dogs?

Many dogs have eaten chocolate, even if their owners are not aware of it, without any harmful consequences. If chocolate is so bad for dogs, why are these dogs doing fine? Dosage, like with everything else, is what makes the difference. The darker the chocolate the more deadly it is because it contains higher concentration levels of caffeine and theobromine. Dogs are poisoned by theobromine and caffeine found in cocoa beans. These toxins are metabolized slowly which allows it to build up in their system. 

Symptoms of Chocolate Poisoning 

If your dog manages to get their paws on some chocolate, they may exhibit some symptoms of chocolate toxicity. Toxic effects of theobromine are mostly directed at the heart and brain. Depending on the levels of theobromine in the chocolate, symptoms may emerge anywhere from four to twenty-four hours after your dog consumes it. Symptoms of poisoning include: 

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

If you notice these toxicity signs in your dog, immediately call your vet and Pet Poison Helpline® for professional advice. 


A dog’s condition is influenced by the amount and kind of chocolate they ate, which in turn affects the treatment they receive. There is no antidote for chocolate poisoning, instead the clinical signs are tended to, and a vet will try to remove the toxins from the body. Medications will be administered to specifically treat symptoms such as vomiting, diarrhea, and heart rate irregularities.
