Acute renal failure as well as a severe anion-gap metabolic acidosis results from the metabolism of ethylene glycol into at least 4 distinct metabolites. Alcohol dehydrogenase, the same first step enzyme responsible for the metabolism of methyl and ethyl alcohols, slowly catalyzes conversion of EG to glycoaldehyde.

Treatment. If your pet ingested ethylene glycol antifreeze recently enough, the one of the first steps in treatment may be to induce vomiting , provided the pet is not yet suffering neurological impairment. The next most critical step is to start the antidote.
How to tell if a dog is intoxicated by ethylene glycol?
It is important to recognize the signs that accompany ethylene glycol poisoning with your dog or cat. Within 30 minutes of ingestion, they may resemble a person who has had too much to alcohol drink. Incoordination, excessive urination, excessive thirst, vomiting, and lethargy are amongst the first signs to appear. Within 24 hours, some animals show apparent improvement which may prevent pet owners from realizing that their pet is in real danger. Unfortunately, during this time of “improvement”, the animal is starting to suffer internal organ damage—specifically to the kidneys. Additionally, their breathing and heart rate will elevate, they may develop acidosis (the pH of their blood decreases), and dehydration typically sets in. The final stage of toxicity includes lethargy, anorexia, seizures, coma, depression, and severe kidney dysfunction (which cause the animal to be unable to produce urine). The final symptom is death. Without medical treatment, your pet may perish.
