Knowing that Sang Su would require more attention than they could provide, staff at the shelter where he initially ended up called the Trio Animal Foundation for help.
The nonprofit group specializes in caring for pets who've experienced profound neglect, but even they couldn't have anticipated the dog's awful state.
"His fur was so tightly wrapped around his legs and ears that it was like a vice," Sue Naiden, president of the Trio Animal Foundation, told The Dodo. "Due to the massive amount of urine-soaked fur that encased Sang Su's body, he was hard for people to stand by because the stench from his fur burned your nose and throat."
But still the dog's rescuers refused to give up on him.
