Antifreeze

There are 3 stages to antifreeze toxicity.  If you notice any of the described signs or symptoms, seek veterinary assistance immediately.

Stage 1 occurs 30 minutes to 12 hours after ingestion and includes:

• nausea
• sudden vomiting
• depression
• ataxia (stumbling around)
• seizures

Stage 2 occurs 12 to 24 hours after ingestion and includes all the signs of Stage 1 as well as the following:

• fast heart rate
• fast breathing rate

Stage 3 occurs 24 to 72 hours after ingestion in dogs, and 12 to 24 hours after ingestion in cats.  Included are the signs of Stage 1 and 2 as well as the following:

• severe depression
• severe vomiting
• diarrhea
• seizures
• coma
• death

Even in small amounts antifreeze is extremely toxic.  Ultimately it causes kidney failure and if left untreated, death.  Pets are attracted to it as it has a sweet taste.  If the pet has been witnessed ingesting antifreeze, immediate treatment is required before absorption of the antifreeze begins.  For dogs, INDUCE VOMITING and seek veterinary assistance for follow-up care.  For cats, seek veterinary assistance immediately.
