Antifreeze Poisoning in Pets: What You Need to Know in 2025 — Vet Safety Guide 🧪🐾
By Dr Duncan Houston BVSc, Ask A Vet Blog
Published: July 7, 2025
When the weather turns cold, antifreeze becomes a common household necessity—but it’s also one of the most deadly toxins for pets. 🧪🐶 Just a few licks can cause severe kidney damage or death.
Here’s everything you need to know to protect your pet from antifreeze and what to do in an emergency. ❗
🧪 Why Is Antifreeze So Dangerous?
The active ingredient in most antifreeze products is ethylene glycol, a sweet-tasting but highly toxic chemical. It targets the nervous system and kidneys, and just a small amount can be fatal. 🚫
📍 Where Pets Encounter Ethylene Glycol
- 🚗 Leaks under car radiators
- 🧊 In toilets to “winterize” pipes
- 🏀 In portable basketball hoop bases
- 🎨 Found in some printer inks, eye masks, and snow globes
- 🎨 Rarely, in household latex paints
⚠️ Signs of Antifreeze Poisoning in Pets
- 🚶 Unsteadiness or “drunken” walking
- 🤮 Vomiting
- 😞 Lethargy or depression
- 🚰 Increased thirst and urination
- 🥣 Loss of appetite
- ⚡ Seizures (advanced stages)
🆘 What to Do If Your Pet Ingests Antifreeze
- 🚑 Go to the vet immediately—time is critical!
- 📦 Bring the product label or packaging
- 🧪 The vet can test your pet’s blood to confirm exposure
💊 Antidotes exist, but must be given ASAP for best outcome—ideally within the first few hours after ingestion. Delayed treatment often leads to irreversible kidney failure. ⏱️
🟢 Safer Alternatives Exist
Look for pet-safe antifreeze containing propylene glycol instead of ethylene glycol. While still a chemical, it has a much wider safety margin.
⚠️ Still, keep all antifreeze products out of reach—no chemical is truly “safe” if ingested. 🧴
