PHILADELPHIA (CBS) — The Pennsylvania SPCA is investigating what it is calling an “extreme” case of animal cruelty: A young female pit bull set on fire Sunday in Germantown has now died.

PSPCA spokeswoman Wendy Marano says the pit bull, named Chloe, was found on Sunday in the 700 block of Gray Avenue, just off Chew.  The dog appeared to have been doused with an accelerant and set ablaze.

Marano says Chloe was transferred to the Animal Alliance of New Jersey, in Lambertville, where she was being given intensive care treatment. Unfortunately, veterinarians have now confirmed that the dog died about an hour after arriving in the intensive care unit.

“This poor creature is just covered in burns and wounds, and is in extreme pain. Our officers are now looking to get information about this case. We do believe that there were multiple witnesses,” Marano told KYW Newsradio earlier on Monday afternoon.

Officials say the dog’s former owner was cooperating with the investigation.

A $500 reward is being offered.  Anyone who has information on the crime is urged to call the Anti-Cruelty Hotline at 1-866-601-SPCA.  All calls will be confidential.
