Boston Terrier Life Span Average Expectancy

I have my first Boston Terrier she is 7 and 1/2 years old her name is Bea and I got her as a rescue from white whiskers senior sanctuary in Buffalo New York. The only problem I have with her is she does not like other dogs and no matter what the size she thinks she can take them on and barks at them. I don’t know if she really would try something I don’t let her get close enough but I still hope to do a meet and greet cuz I’ve always had more than one dog at a time any recommendations and how to handle this I’d appreciate and although I grew up going to dog shows with our German Shepherds and Pembroke welsh corgis and have had many other breeds since I’ve fallen in love with this little girl.

Our oldest Bostons were 14 and one was almost blind and partially deaf at this age. He was still very spunky tbough!

I had a lovely Boston puppy who lived to be 18. He was a wonderful show quality boy who won three championships. At 15, I showed him in an AKC Boston specialty show and he was placed first Award of Merit. At that age, he looked about 7, in great shape with not one grey hair. He passed in his sleep at 18, still as handsome as ever.
He was the sweetest boy. I have had many lovely Bostons, but Sean was very special. He loved everyone, and everyone loved him.

Why do Bostons seem to have so many problems
Is it the Breeding?

Our precious baby Nero lived to be 18.
He was mostly blind but had a stroke and had to cross the rainbow bridge.
We have a 4 year old now and hope he out lives us.
