Act quickly! If you suspect your pet has consumed antifreeze you must take your pet to a veterinarian immediately. Animals who have ingested antifreeze go through two stages of symptoms. If untreated, death from kidney failure will occur within days.
Stage 1
In the first hour after drinking antifreeze, animals will stagger, act uncoordinated or disorientated, possibly bumping into things. They may also try to vomit. The quicker you get to the vet the better chance your pet can be successfully treated.
Stage 2
After stage 1 it may appear your pet has recovered. However, in this stage the antifreeze is being processed by the liver, creating substances that cause permanent kidney damage as well as signs of central nervous system damage. The more antifreeze the pet has ingested the more damage. Eventually the animal will lapse into a coma. Death usually occurs within 48 hours.
Veterinary care
Immediate treatment is critical. If you suspect your pet has been poisoned, take your pet to a veterinarian. Your pet will NOT recover without treatment.
