Actually, it was Very Serious. Think no waiting in the ER. Think immediate CAT scan. Think vampire (phlebotomist) leaving the room with a double handfull of blood tubes, some of which are the honkin' big purple top tubes. Think docs with Serious Faces.

I was a Very Sick Puppy. Oddly, except for the breathing problem, I really didn't feel all that bad. That's the scary part, DVTs don't hurt.
