Underlying renal insufficiency and hepatic dysfunction raise risk for toxicity. Experts note that factors that affect the risk of poisoning when exposed to ethylene glycol include its dose, duration and nature of contact. Antifreeze poisoning in dogs is a very serious matter. Although it is considered safe, large intravenous doses given over a short period of time can be toxic. Containing two alcohol groups, it is classed as a diol.It is miscible with a broad range of solvents, including water, acetone, and chloroform.In general, glycols are non-irritating and have very low volatility. While propylene glycol antifreeze is more expensive, it’s safe for pets and other wildlife, so please consider using this instead. Propylene glycol, although not entirely nontoxic, is considerably less toxic than ethylene glycol and has been reported to affect the central nervous system but not the kidneys. Share this support centre article. AU - Claus, Melissa A. Ethylene glycol poisoning is common because antifreeze is widely used, it has a sweet taste and small lethal dose (only 3 to 4 teaspoons in dogs, 1 to 2 teaspoons in cats), and it is often stored and disposed of improperly. Toxicity and death may occur after drinking even a small amount. Tufts Veterinary Newsletter reported that a medium-sized dog would have to ingest about 20 ounces of propylene glycol before getting seriously ill. Antifreeze poisoning in dogs. The oral median lethal dose (LD50) of propylene glycol in dogs has been reported to be ~9 ml/kg body weight. The oral LD 50 of PG in dogs is ~9 mL/kg. It has occasionally been substituted for propylene glycol in pharmaceutical preparations, resulting in the deaths of more than 100 persons in some incidents. Ingestion of ethylene glycol (EG) is a frequently encountered toxicity in dogs and cats. Later symptoms may include a decreased level of consciousness, headache, and seizures. Fomepizole (Antizol-Vet®, 4-methylpyrazole) is the treatment of choice for ethylene glycol poisoning in dogs.

Until 1996, almost no data existed on the incidence of ethylene glycol (antifreeze) poisoning. A dog only needs to ingest 2 to 3 milliliters of ethylene glycol per pound of body weight to get a lethal dose of the toxin; cats only need to ingest 0.64 milliliters for the same effect. 13 Ethylene glycol is especially dangerous since it only takes about 3oz to poison a medium-sized dog. Ethylene Glycol Poisoning in Dogs (In addition to being found in the car's engines to prevent freezing and overheating, it is used in hydraulic brake fluids.) Although less toxic than EG, ingestion of propylene glycol (PG) may be associated with a toxic syndrome similar to the acute phase of EG toxicosis. Should a dog lick up some concentrated Propylene Glycol – even 1 to 1.5 teaspoons full – that can be enough to begin to cause issues. Long term outcomes may include kidney failure and brain damage. Propylene glycol (IUPAC name: propane-1,2-diol) is a viscous, colorless liquid, which is nearly odorless but possesses a faintly sweet taste.Its chemical formula is CH 3 CH(OH)CH 2 OH. Many dog owners know that antifreeze is poisonous to dogs, but not all people understand how dangerous antifreeze poisoning can really be.Unfortunately, exposure to even a small amount of toxic antifreeze can quickly lead to death. If the above wasn’t enough, polyethylene glycol also destroys the beneficial bacteria found on your dog’s skin and inside their stomachs. If cats or dogs ingest large amounts of propylene glycol, poisoning can occur.. Yet because of its proven ability to cause a serious type of blood disease in some animals — Heinz body anemia — propylene glycol has been banned by the FDA for use in cat food. Dr. Hotchkiss says that what makes ethylene glycol such a dangerous and common form of poisoning is that the toxin’s sweet smell and taste appeals to an animal’s sweet tooth. Zinc, copper, and naphthalene poisoning are other types that will need to be ruled out. It is the best thing you can do to prevent poisoning in your pets however, it does not eliminate it from guests and neighbors.

With the increasing popularity of e-cigarettes, comes an increased risk of poisoning in dogs whose owners use them. Request PDF | Propylene glycol intoxication in a dog | To describe the clinical course, treatment, and outcome of a dog with propylene glycol intoxication. Propylene glycol antifreeze products are more environmentally friendly, and in addition to being less likely to cause fatal poisoning, they don’t taste like candy the way ethylene glycol products do, so … Propylene glycol is a controversial additive used to help preserve the moisture content in some commercial dog foods. Over 10,000 dogs and cats are poisoned with automotive antifreeze each year. This is most commonly seen when pets ingest liquid, high concentration propylene glycol … AU - Jandrey, Karl. Large doses and unusual circumstances are necessary for the development of propylene glycol toxicity. Earlier this year, the manufacturer of the preferred antidote (remedy for the poison) for treating ethylene glycol poisoning in cats and dogs asked the FDA to pull their approval for the drug — called fomepizole (a.k.a. Antifreeze is an engine coolant. Antifreeze, specifically ethylene glycol, is a highly toxic substance that smells and tastes sweet to pets and can cause serious, sometimes fatal health problems in both cats and dogs. The ingredient found in antifreeze that is poisonous to dogs and cats, is ethylene glycol, which make up 95 percent of the antifreeze. Symptoms of Chemical poisoning - Propylene Glycol including 10 medical symptoms and signs of Chemical poisoning - Propylene Glycol, alternative diagnoses, misdiagnosis, and correct diagnosis for Chemical poisoning - Propylene Glycol signs or Chemical poisoning - Propylene Glycol symptoms. Automotive antifreeze kills 10, 000 of these pets every year. 2 Ethylene glycol is most commonly found in automotive antifreeze and is also used as a precursor to industrial polymers. T1 - Propylene glycol intoxication in a dog. Sadly, most manufacturers don’t know about all the research being done into polyethylene glycol and its derivatives. Dogs rely on these bacteria for a healthy immune system and a balanced pH level. 2 – 11 The most recent mass DEG poisoning occurred in India in 1998. Propylene glycol toxicity is metabolized to compounds that are normal constituents of the citric acid cycle. Antifreeze poisoning in dogs is a very serious matter. The dog made a full recovery. Prevention is key. Antifreeze poisoning is the most common poisoning of dogs and cats in the United States. With that said, while dog food may contain 5-10 percent of Propylene Glycol and not be toxic for them, that’s in a diluted form mixed with other food matter. Ethylene Glycol (Antifreeze) Poisoning Basics OVERVIEW • Results from ingesting substances containing ethylene glycol (such as antifreeze) • Common in small animals (such as dogs and cats) • Highest fatality rate of all poisons; fatality rates higher for cats than dogs Antifreeze. Experimentally, propylene glycol administration in dogs at 2 g/kg/day has caused no adverse effects.” Propylene glycol poisoning, acetaminophen, vitamin K, or benzocaine toxicity symptoms are similar to chives poisoning symptoms. These 95% commercial antifreeze preparations are diluted ~50% with water when used in vehicle cooling systems. Propylene glycol poisoning is marked initially by CNS depression and an elevated osmolal gap and, later, by an increased anion gap. There are a few differential diagnoses of chive poisoning in dogs. The most toxic kind contains ethylene glycol, but some contain methanol or propylene glycol, which may not be as toxic but can still make your dog unwell. Therefore, now the ethylene glycol has been replaced with propylene glycol. 12 Almost all (98%) affected children died in a 1996 epidemic in Haiti. 4-MP) — because they have discontinued production of the drug.

In cats, ingestion of a diet containing 6%–12% PG can result in Heinz body formation and decreased RBC survival. It is believed that background concentrations of ethylene glycol in air, soil, surface and groundwater do not lead to poisoning. It is given intravenously for 36 hours, and stops the metabolism of ethylene glycol into its damaging metabolites. Antifreeze Toxicity in Dogs. New or Unique Information Provided. Three stages of poisoning can be seen with ethylene glycol: Antifreeze products will mostly contain Ethylene glycol, Propylene glycol or … However, propylene glycol is considerably safer (less toxic) than its far more dangerous cousin — ethylene glycol. Dogs usually come into contact with antifreeze when it leaks from a car's engine onto the ground, when it is spilled onto the ground while being added to a car's engine, or when the container is left uncapped.
