During yesterday’s walkabout in Scituate, MA, I had to smile at the sight of “Toto” patiently waiting while his “Dorothy” was shopping or doing errands. It’s not yet hot enough here in New England to worry about leaving your little dog, too, in the car while you’re off mingling with lions and tigers and bears, oh my! But as soon as temperatures rise to match the sunny days we’ve been having, you’ll want to keep Toto out of your closed car lest he become a hot dog.
