Antifreeze should be out of pet’s reach. Antifreeze, which contains ethylene glycol, is extremely poisonous; a few teaspoons can be lethal. Its sweet taste attracts pets and ingesting even a tiny amount causes fatal kidney toxicity. So, when tuning up your car for that holiday trip, make sure your pet does not have access to antifreeze containers and clean up any spills immediately. If you think your pet has consumed antifreeze, contact your veterinarian immediately. Time is of the essence.
