Who knew?

So my dog Izzy taught me something new today.  I previously had no idea that dogs could poop their pants!

One of my dogs, Isabelle (Izzy) is pretty strange.  She's afraid of loud noises, new people, going outside, pretty much anything outside of her normal routine (except the going outside part, but that fear comes and goes).  We don't know why she's that way; she's never been abused (we've had her since she was about 8 weeks old, from the SPCA -- whatever those 8 weeks may have been like we do not know, but I can't imagine she'd remember... ?).  It just seems to be in her genetic make-up to be a fraidey cat.
My other dog, Peanut, as a LOT of energy and is very athletic.  She gets to run around in our backyard, but that alone isn't really enough to get all of her energy out.  She recently discovered that among her athletic abilities is the capacity to jump over our SIX FOOT privacy fence.  She doesn't do it very often, however, only when she is really worked up for some reason.  So I decided (after her latest jump) that she needs to go on at least four walks a week.
So today was to be the first walk.  As soon as I got home, I changed clothes,  As I'm putting on her leash I say to myself, why not take Izzy, too?  I mean, she's not as full of energy, but what dog doesn't love a walk?  I guess Izzy doesn't...
So, yeah, while we're out, a lady who is talking on the phone on her porch calls out to me and asks me about Peanut.  She was saying that she saw her running around the other day (the day of her last jump) and wanted to know if she was friendly, etc.  Then the dogs and I get back on our way.  And in front of me I see Izzy's butt.
Izzy has pooped her pants.
No, I don't put pants on my dog, and I know that dogs poop naked every day and don't typically fail at it.  But Izzy's tail was tucked so far between her legs, and then she was so freaked out by me talking to that lady, that she pooped.  Right there, standing up.  On her tail.  And do you know, she walked all the way home that way until I let her in the backyard.  She took care of most of the business then, but I still had to give her a bath.
She's now chilling out on her favorite blue chair like the world is awesome.  Thanks a bunch...
