name some ..
I don't think she means a particular breed...she's talking more about individual dogs. (Sorry if I'm wrong with my 'interpretation' here...just trying to help! )

Anyway...I can think of plenty of large dogs I have known that have lived well into their teen years. My friend had a Mastiff that lived to be 15, and my uncle has two Bernese Mountain Dogs that are already 14 and still have a lot of life left in them.

It varies from dog to dog...you really can't be too judgemental.
