The average lifespan of frogs is between 10 years to 12 years.
Tree frogs have been known to live for up to 15 years though so it can depend on the type and species of frog as to their lifespan.
But 15 years is about the longest life that a frog of any type can live for although it's possible for frogs to sometimes outlive their lifespan.
Just like dogs and humans can outlive their lifespan frogs and other animals can as well.
But if you have a pet frog you can expect it to live at least 10 years minimum unless it gets sick or has any other injuries or illnesses as well.
