Propylene glycol

Severity scale:
Caution
This toxin is considered to be a moderate risk. However, your pet's medical history, age, weight, and breed could put him/her at higher risk. It is advised that you contact whiskerDocs or your primary veterinarian for further guidance about any steps you may need to take to ensure your pet's safety. If you choose to, you may monitor your pet closely, but the onset or worsening of any of the below symptoms warrants a trip to the emergency room.

Propylene glycol is technically safer than ethylene glycol. Often used as an additive alternative to ethylene glycol in antifreeze products, it is also found in e-liquids for e-cigarette or vape products and even in human foods. Antifreeze products containing propylene glycol, usually at a concentration of 50% or less, such as SierraTM and Prestone LowTox® are safer than traditional antifreeze and are unpleasantly flavored to prevent ingestion. These safer products will not metabolize into oxalate, but even pet-safe products containing propylene glycol could cause other problems including nervous system injury resulting in incoordination and possibly seizures, along with severe anemia.

RV and "pet-friendly" antifreeze, vaporizing e-liquids, and many foods also contain small amounts
