Why does "super-wife" have a pit bull sitting in her lap?

When we visited our son Justin and his wife Lauren for Thanksgiving we met our new "grand dog" Latte.  She's a pit bull-beagle mix.  Now for us over sixty type that was kind of a surprise.  Here in the midwest we see pit bulls through a different filter.

Latte was charming, laid back, liked to cuddle on the couch and had painted toe nails.  She had big eyes and big teeth and looked like she had the strength to pull a Honda Civic out of a ditch.  

She was a delight much like her owners and how they live life.  Very comfortable with others, like to get out see things and meet people and have a little snap, crackle and pop in their smiles.
