My Dog Has Blue Poop

So last night before we left for the game I left a blue pen on the top of Belle's kennel. Like a good dog, she managed to drop the pen down where she could reach it in the kennel and then proceeded to tear it apart leaving ink all over her pillow and blanket. After we came home we didn't notice right away, eventually Chris noticed the pillow and we found the remains of the mangled pen ALL over her kennel. So we cleaned it up and that was that. Later on Chris took Belle out to go to the bathroom and when she came back in and he was drying (it was raining) her off he noticed her front right paw was BLUE where it is normally white. Once again we thought her blue paw and now blue pillow was the end of it. Well little did we know that when she went out this morning we would get a special surprise. Sure enough when she pooped this morning she had 3 very nice and bright blue poops!!!! Moral of the story.....don't let your dogs eat pens;)
