dead small furry animal

oh my goodness! my dog killed a small furry animal. I discovered it rotting away in my vegetable garden. I left it there because I was so shocked. its not such a vegetarian vegetable garden any more. whats worse, is that it is midnight, and he must have dug it up. the stench is so unbelievably bad. he is no longer welcome in my art room. he is no more my studio assistant untill he is given a bath. oh my goodness, i have never smelt anything so strong or so awful in my life!
