Chihuahua + Antifreeze (Ethylene Glycol)

NO. Take immediate action.

The verdict

For a 5lb Chihuahua, even a very small amount of antifreeze (ethylene glycol) is extremely dangerous and potentially lethal due to their low body weight. Their small size means the toxic dose is significantly lower, leading to rapid onset of severe systemic effects.

Watch for these signs (next 12 hours)

  • Vomiting and diarrhea
  • Lethargy and weakness
  • Increased thirst and urination

Recommended next steps

Seek immediate emergency veterinary care without delay; time is absolutely critical for ethylene glycol poisoning. A veterinarian can administer specific antidotes like fomepizole or ethanol, which are most effective if given within the first few hours of ingestion. Do not wait for symptoms to appear, as by then significant organ damage may have already occurred.
