Antifreeze poisoning is very common in dogs and cats. Why is antifreeze so fatal? Antifreeze contains ethylene glycol, making it one of the most toxic common household items for pets. Less than three ounces of antifreeze could be fatal to your pet and immediately affects the brain, liver and kidneys. Ethylene glycol may also be found in engine coolant and hydraulic brake fluid.

Common Symptoms of Antifreeze Poisoning in Pets

  • Rapid heartbeat
  • Vomiting
  • Uncoordinated movement
  • Diarrhea
  • Excessive urination
  • Weakness

These symptoms appear in three stages.

The first stage can occur within 30 minutes to 12 hours. In the first stage, your pet may appear dazed. He may also experience vomiting, seizures, diarrhea, and/or excessive drooling. In stage two, which occurs within 12-24 hours, your pet may experience organ failure. The third stage is 36-72 hours following ingestion, severe kidney failure will begin. Symptoms found in the third stage include lethargy, coma, vomiting and/or seizures. This is why immediately following ingestion, you must seek treatment.

If you suspect your dog may have ingested antifreeze, you should consult with your veterinarian immediately. Your doctor may instruct you to induce vomiting immediately by providing your dog with one teaspoon of hydrogen peroxide per five pounds of body weight. He may also instruct you to take your dog to an emergency clinic immediately. Your veterinarian will likely draw blood and collect a urine sample to ensure your dog’s body is safe from harm.

How to Prevent Antifreeze Poisoning

  • Clean up spilled antifreeze promptly
  • Ensure you dispose of antifreeze containers immediately
  • Do not allow your dog or cat in any area where antifreeze may be left
