myPET Podcast: Chocolate: Deadly For Dogs

With Easter approaching, this episode explains why chocolate can be dangerous for dogs, what makes some types more toxic than others, the symptoms owners should watch for, and how veterinary treatment works. It highlights why “they’ve eaten it before and were fine” isn’t a guarantee of safety and why early action leads to better outcomes.

Podcast Summary: Chocolate Toxicity in Dogs – What Every Owner Should Know

  • Chocolate contains caffeine and theobromine; dogs metabolise theobromine poorly, allowing toxic levels to build up.
  • The darker and more bitter the chocolate (higher cocoa content), the more dangerous it is.
  • Cooking chocolate and high-percentage dark chocolate pose the greatest risk.
  • Small dogs are at higher risk because it takes much less chocolate to reach a toxic dose for their body weight.
  • Symptoms may take 6–12 hours to appear and can last up to 48–72 hours depending on the amount consumed.
  • Common signs include hyperactivity, rapid heart rate, heart rhythm disturbances, tremors, seizures, vomiting and diarrhoea.
  • Chocolate can act as a diuretic, causing increased thirst and urination and leading to dehydration or electrolyte imbalance.
  • Large amounts of milk chocolate may also trigger pancreatitis due to fat and sugar content.
  • Packaging (foil and wrappers) may pass through but can occasionally contribute to vomiting or obstruction concerns.
  • Early treatment focuses on inducing vomiting (when safe), administering activated charcoal, and providing supportive care.
  • Severe cases may require sedation, general anaesthesia with stomach lavage, IV fluids, cardiac monitoring and seizure control.
  • Most dogs recover fully if treated early, with few long-term effects unless complications develop.
  • If exposure is suspected and the amount is unknown, it is safest to assume risk and contact a veterinarian immediately.
