How long would a Rat Terrier Mix live? Kirsten is 3 years old. I have no idea what she is mixed with though. Her mother was a purebred Rat Terrier and her father was unknown. I'm just curious what the average life span would be. She is about 20 lbs.

First of a small breeds tend to live a few years longer than larger dogs. Secondly mixed breeds are sometimes more genetically sound than purebreds. Mutts who have been multi generation random bred can have natural selection on their side.

Small terrier types often have longer and healthier life spans.

I would say there's a good chance the dog can live past 14 years. The lifespan also depends on the dog's life. Happy and healthy dogs live longer than bored depressed overweight dogs.
