Ethylene glycol antifreeze is extremely toxic to dogs and cats and causes agonizing deaths that are entirely preventable.
Antifreeze poisoning causes one of the most agonizing deaths possible for companion animals. Ethylene glycol is metabolized to compounds that crystallize in kidney tubules, causing acute renal failure over 24-72 hours. During this progression, affected animals experience progressive nausea, neurological effects from metabolite toxicity, and eventually the profound malaise of acute renal failure with uremia. The prevention is straightforward: storing antifreeze properly, cleaning up spills immediately, and where possible using propylene glycol alternatives. The tragedy is that many antifreeze poisonings occur because animals discover puddles of leaked coolant in driveways and garages - a completely avoidable exposure. Immediate veterinary treatment is effective if sought within hours of ingestion, making rapid recognition and response critical for any owner whose pet may have had antifreeze access.
