Who turned the STINK on?

Gaaa.... The dog rolled in something outside for sure. Why do they do that?? What possesses a perfectly clean dog to roll around in dead animal? So on my way to the groomers this morning, I caught site of her in the rear view mirror. I thought this was a funny photo. But I wasn't laughing at the time because we were stopped in the construction zone and the odor coming off that dog was making me gag. Obviously, if she had to stick her snout out the window for fresh air , she was making herself gag too!
