Oh the carnage!

It's always wonderful to be greeted by your husband with "you're not going to like this" after a long day of work. So, everyone...here is my left slipper.
And, here is my right slipper.

And, this is the carnage.

According to Tommy, Carter never liked these slippers. Can someone help me understand how I can own these slippers for well over a year and my dog chooses today to eat them?
