I want to know the answer to the following question:
What is the average length of years of life for canines with long lifespans?
All the background I'm provided with is that "The longest-lived breeds, including Toy Poodles, Japanese Spitz, Border Terriers, and Tibetan Spaniels, have median longevities of 14 to 15 years.". Is that enough to answer the question?
Answer: yes
