The only thing that our dog has ever done that I've found disgusting was when he used to manage to find cat poop and eat it...any thing else is just typical of dogs and doesn't really bother me.
I was bike riding years ago and my dog suddenly ran off into an overgrown abandoned property. I called him several times to no avail, dismounted my bike and walked into the shade of trees. There were way too many flies. Ahead in the shadows I could see the dog was rolling on something. Stepping closer I came to realize he was rolling on a dead horse! That dog was just nasty. @Lostpoet
@indyjoe that's how she was too. My brother said it was a survival instinct and that she was trying to mask her scent. I think she just wanted attention.
