DETROIT -

The reward being offered in the search for a person responsible for skinning a dog has been increased to $8,500.

The Michigan Human Society Cruelty Investigation Department, the Humane Society of the United States and Providing for Paws have joined to offer the higher reward. The dog, given the name Patty, was found partially skinned alive and stabbed last week on Woodmere Street in southwest Detroit.

Patty underwent surgery at Emergency Veterinary Hospital in Ann Arbor. Veterinarians tried to reattach fur that was hanging off of her body but could not do it.

Many are calling it one of the worst cases of animal cruelty.

Anyone with information on who may have done this to the dog is asked to contact the MHS hotline at 313-872-3401.
