When the kind souls at the Trio Animal Foundation in Chicago found this dog at a local shelter, they "didn't know which end was front or back." The poor dog was covered in flies and gnats, matted fur, other debris and its own urine.

"We had to get a treat to see which end lifted up to sniff," Sue Naiden, who founded TAF and pulled the dog out of the shelter, explained on Facebook. "We couldn't even figure out if the dog was a male or female."

Sue called in Kelli, a groomer at Mutt Hutt, for a haircut. They learned the pup was a girl.
