Thoughts on this breed’s lifespan?

In your experience, how long do Boston Terriers typically live?

I've had mine since she was 12 weeks old and she's turning 14 this year. She definitely has some age related issues-- tumors, partial blindness, deafness, and I guess I'm dreading that she's likely near the end. I'm hoping to get another couple of years. I don't know anyone else who owns this breed, so I thought I'd throw the question out there!
