Experimentally, propylene glycol administration in dogs at 2 g/kg/day has caused no adverse effects.” 2 Ethylene glycol is most commonly found in automotive antifreeze and is also used as a precursor to industrial polymers. In cats, ingestion of a diet containing 6%–12% PG can result in Heinz body formation and decreased RBC survival. 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. New or Unique Information Provided. It is believed that background concentrations of ethylene glycol in air, soil, surface and groundwater do not lead to poisoning. AU - Jandrey, Karl. There are a few differential diagnoses of chive poisoning in dogs. To the authors' knowledge, this is the first report of documented propylene glycol intoxication in a dog, as well as the first report to describe hemodialysis as treatment for propylene glycol intoxication in a dog. If the above wasn’t enough, polyethylene glycol also destroys the beneficial bacteria found on your dog’s skin and inside their stomachs. Antifreeze poisoning in dogs is a very serious matter.

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. Propylene glycol poisoning, acetaminophen, vitamin K, or benzocaine toxicity symptoms are similar to chives poisoning symptoms. Ingestion of ethylene glycol (EG) is a frequently encountered toxicity in dogs and cats. 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. Sadly, most manufacturers don’t know about all the research being done into polyethylene glycol and its derivatives. Propylene glycol products are biodegradable, anti-corrosive, and recyclable. The dog made a full recovery. Three stages of poisoning can be seen with ethylene glycol: Therefore, now the ethylene glycol has been replaced with propylene glycol. The oral median lethal dose (LD50) of propylene glycol in dogs has been reported to be ~9 ml/kg body weight. It has occasionally been substituted for propylene glycol in pharmaceutical preparations, resulting in the deaths of more than 100 persons in some incidents. 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. T1 - Propylene glycol intoxication in a dog. It is a colorless, odorless, and sweet-tasting solution. Propylene glycol is a controversial additive used to help preserve the moisture content in some commercial dog foods.. You may already recognize this chemical for its more everyday use — as the key component in newer automotive antifreeze.. All animals are susceptible to ethylene glycol (EG) toxicity, but it is most common in dogs and cats. DEG is less toxic than ethylene glycol in most species, but more toxic than propylene glycol. Until 1996, almost no data existed on the incidence of ethylene glycol (antifreeze) poisoning. Most intoxications are associated with ingestion of antifreeze, which is typically 95% EG. 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. It is given intravenously for 36 hours, and stops the metabolism of ethylene glycol into its damaging metabolites. 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. 2 – 11 The most recent mass DEG poisoning occurred in India in 1998. Later symptoms may include a decreased level of consciousness, headache, and seizures. 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. Request PDF | Propylene glycol intoxication in a dog | To describe the clinical course, treatment, and outcome of a dog with propylene glycol intoxication. Antifreeze Toxicity in Dogs. Antifreeze can be extremely dangerous to dogs. 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 … Antifreeze. The oral LD 50 of PG in dogs is ~9 mL/kg. Zinc, copper, and naphthalene poisoning are other types that will need to be ruled out. Propylene glycol is an effective alternative to ethylene glycol and the FDA has recently labeled propylene glycol safe. 12 Almost all (98%) affected children died in a 1996 epidemic in Haiti. 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. Antifreeze poisoning is the most common poisoning of dogs and cats in the United States. These 95% commercial antifreeze preparations are diluted ~50% with water when used in vehicle cooling systems. 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. Some “pet-safe” antifreeze products contain propylene glycol, which is much safer than ethylene glycol if ingested. Prevention is key. 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. 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. Is antifreeze dangerous to dogs? Ethylene glycol is especially dangerous since it only takes about 3oz to poison a medium-sized dog. 4-MP) — because they have discontinued production of the drug. “Propylene glycol ingested at toxic doses can cause central nervous system depression and lactic acidosis, Brutlag says. Although it is considered safe, large intravenous doses given over a short period of time can be toxic. Propylene glycol toxicity is metabolized to compounds that are normal constituents of the citric acid cycle. Early symptoms include intoxication, vomiting and abdominal pain. With the increasing popularity of e-cigarettes, comes an increased risk of poisoning in dogs whose owners use them. Experts note that factors that affect the risk of poisoning when exposed to ethylene glycol include its dose, duration and nature of contact.
