Chocolate contains theobromine and caffeine, which dogs cannot metabolize as well as humans can. These chemicals act as a heart stimulant, blood vessel dilator, and smooth muscle relaxant.

*Though white chocolate does not contain hazardous amounts of theobromine or caffeine, it is high in fat and sugar which can still cause tummy troubles.



Severity depends on your dog’s size and the type and quantity of chocolate they ate.

  • Vomiting
  • Diarrhea
  • Restlessness
  • Rapid breathing
  • Increased heart rate
  • Seizures
  • Increased urination
  • Heart attack

What should I do if my dog consumed chocolate?

  • Call your veterinarian or the Pet Poison Helpline ASAP to determine if your dog needs veterinary care.
  • Do not induce vomiting unless advised by a veterinarian.
  • Veterinary treatment may include inducing vomiting, activated charcoal, IV fluids, and anti-seizure drugs.

If you suspect your pet has ingested hand sanitizer, call The Pet Poison Helpline (available 24/7) at 855-764-7661 or get to a veterinarian or emergency veterinary hospital immediately. A consultation fee may apply for the helpline.
