Dogs will eat anything, but why clothes or shoes!

So I woke up this morning to the sounds of my dogs playing with something, I look out my window and see that they have my LEATHER JACKET in theirs mouths and are playing tug-o-war with it........ REALLY?!?!?!?!?What is it about our fashion items that dogs love to eat so much. Like shoes, good shoes, expensive shoes. (If you scroll down there's a picture of the angels) Its not like they will take the shoes and hide them, they take them and leave clear out in the open and decide to put teeth marks along the heel or the front where your toes show.

I love my pups, but come on, leather jacket!
