Project Description
Propylene glycol is found in many household products and has a significant toxic risk if ingested by pets. Of note, it is commonly found in ‘pet-safe’ anti-freeze products. While this form of anti-freeze is less toxic than those containing ethylene glycol, these products still pose a risk to pets if ingested.
Propylene glycol can also be found in RV antifreeze, hair dyes, disinfectants, paints and varnishes.
Signs and symptoms of toxicity: Initial signs of toxicity include depression, weakness, involuntary muscle movements, increased urination, and increased thirst. Low blood pressure, cardiovascular collapse, and seizures can also occur. There is a risk of lactic acidosis and Heinz body anemia (in cats) developing later.
Toxic consumption: In dogs, 9 mL/kg (4.1 mL/lb) can be fatal. There is no established toxic threshold in cats. All incidents of accidental consumption should be reported.
