Were as offended by that a I was? I had a dog once when I was kid. A cocker spaniel named Blackie. My folks gave him to a friend who had farm so I never personally experience having my dog die. I have experienced it with cats.
But my friend has two dogs..Nellie and Harley. He loved them both dearly and when Harley passed away his grief was real. All his friends grieved for him. Harley was a wondrous dog. Almost human but then aren't all dogs like that?
So to say about a terrorist that "HE DIED LIKE A DOG" I think is vile and evil and shows how little motormouth cares about living things.
