MINNEAPOLIS — A Twin Cities foster care program says a dog is thriving after surviving what appears to be a chemical attack in Missouri.

Secondhand Hounds volunteers said the dog they’ve nicknamed “Coen the Survivor” is missing his fur and is 20 pounds underweight. The nonprofit launched an online fundraising drive for Coen’s medical treatment on Wednesday in hopes of raising $3,000 in 50 days. They met the goal in a matter of hours.

A Kansas City shelter told the Minneapolis group that someone had doused him in gasoline or acid. Veterinarians are trying to determine whether he suffers from an auto-immune disease instead.

Volunteers said he could be an Australian shepherd or Great Dane hound mix. His paperwork lists him as a stray with no backstory.
