Antifreeze is one of the most dangerous household chemicals for pets. The active ingredient, ethylene glycol, has a sweet taste that attracts dogs and cats, but it can cause rapid, irreversible kidney damage and death even in tiny amounts. Prompt treatment within the first few hours is often the only way to prevent a fatal outcome.
Pets are usually exposed by licking spills from driveways, garage floors, or leaking radiators. They may also chew open containers or walk through puddles and then groom their paws. Because it only takes a very small volume to poison a dog or cat, any suspected contact should be treated as a life-threatening emergency.
Keep all antifreeze containers tightly sealed and stored on high shelves behind locked cabinet doors. Clean up spills immediately with absorbent materials and rinse the area thoroughly with water. Consider switching to products made with propylene glycol, which are labeled "pet-safe" or "non-toxic" and are far less dangerous if accidentally ingested.
If you suspect your pet has been exposed to antifreeze, call your veterinarian or an animal poison control center right away. Do not wait for symptoms to appear, since treatment is most effective in the early stages and kidney failure can progress quickly.
