Antifreeze is one of the most dangerous and common household toxins for pets. Even a small amount can be life-threatening, making awareness and quick action essential. As temperatures drop and vehicles, garages, and driveways see more antifreeze use, now is the time to understand the risks, symptoms, and emergency steps that can save your pet’s life.
Why Antifreeze Is So Dangerous
Antifreeze, also known as ethylene glycol, has a sweet taste that attracts pets, but it becomes toxic within minutes of ingestion. Just a teaspoon can be fatal for a small dog or cat. Because symptoms escalate quickly, immediate emergency care is critical.
Common sources include:
- Leaks from cars and trucks
- Spilled antifreeze in garages or driveways
- Open containers left within reach
- Contaminated puddles near sidewalks or parking areas
- Certain engine coolants or winterizing products
Early Signs of Antifreeze Poisoning
Symptoms can appear within 30 minutes of ingestion, and knowing what to look for can mean the difference between life and death.
Early stage signs:
- Vomiting
- Excessive drooling
- Loss of coordination or stumbling
- Increased thirst and urination
- Seizures
Later stage signs, typically appearing 12 to 24 hours after ingestion:
- Lethargy or collapse
- Decreased urination
- Rapid heart rate
- Kidney failure
- Coma
If your pet displays any of these symptoms and there is a possibility they accessed antifreeze, seek emergency care immediately.
What To Do If You Suspect Antifreeze Exposure
Time is critical. The sooner your pet receives care, the better the outcome.
- Bring your pet to a veterinary emergency hospital right away
- If possible, bring the antifreeze container or a photo of the product
- Do not attempt home remedies or wait to see if symptoms improve
- Prevent your pet from licking paws or fur that may be contaminated
Prompt treatment, including decontamination and specific antidotes, can dramatically improve survival rates when started early.
Prevention Tips for Pet Owners
Simple precautions can prevent accidental exposure.
- Store antifreeze and all automotive fluids in tightly sealed containers
- Clean up spills immediately and thoroughly
- Regularly check your vehicle for leaks
- Choose pet safe propylene glycol based antifreeze when possible
- Block access to garages, driveways, and workshops
