Why Antifreeze Is Toxic
Antifreeze contains ethylene glycol, which is highly toxic to pets.
Even small amounts can cause severe kidney damage and central nervous system depression.
Why speed matters
Delaying care significantly worsens outcomes. Some signs appear hours or days later, so "looks fine right now" is not a reason to wait.
Symptoms of antifreeze-toxicity poisoning
- Vomiting and diarrhea within 12-24 hours after ingestion.
- Lethargy or weakness.
- Increased thirst and urination.
- Severe abdominal pain.
- Kidney failure and death.
What to do right now
- Keep antifreeze containers tightly sealed and out of reach of pets.
- Wipe up spills immediately and clean contaminated areas thoroughly.
- Call your vet or a poison line immediately if you suspect your pet has ingested antifreeze.
- Know the symptoms of antifreeze poisoning and seek veterinary care if necessary.
