I had a dog ...
... the poor pooch starved to death when my day trip to Dallas turned into an one-night stay for a 2nd meeting, then a two-night stay on account of weather.
Just kidding!
Seriously, with all the traveling, it's tough to take care of a pet. My dog goes through separation anexiety when I am away, regardless of who is watching him. He gains weight and does not want to fetch or play.
