Chocolate Poisoning

Chocolates, chocolates, chocolates! Humans love them... and pets love them! But to most pets, they’re poison! That’s right... poison!

Chocolates contain methylxanthines, and although not toxic to humans in the amounts found in chocolate candies, they can be deadly for dogs. The smaller the dog, the less chocolate they have to eat for death to occur. A general rule of thumb can be found in the following table:

Dog’s Weight

Lethal Dose Of Chocolate

5 - 10 Pounds

As Small As Four Ounces

20 - 40 Pounds

As Small As 16 Ounces

The following symptoms may appear within hours of eating chocolate:

  • Hyperexcitability
  • Vomiting
  • Frequent Urination
  • Diarrhea
  • Rapid Breathing
  • Weakness
  • Seizures
  • Coma

If you suspect your dog has eaten chocolates, determine the type of chocolate (if possible) and call your Veterinarian or Emergency Care Clinic immediately! If you can’t reach either of them and know your dog has eaten chocolates within the past 6 hours and has not as yet vomited, induce vomiting immediately and pursue calling your Veterinarian or Emergency Care Clinic.
