Cats & Dogs - has anyone figured out exact lifespan?

I play with mccc and a custom life span , i have my game on long and my sims dog was 10 days as a puppy and has 78 days as an adult , i have the control pet mod so it shows how long they have.
Normal life span only showed 4 days as a puppy and 20 days as a adult. I thought that was to short but 78 to long if mccc does pets i can do a custom life span for them to.
