DETROIT -

The reward being offered in the search for a person responsible for skinning a dog has been increased again. It's now up to $10,000.

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.

"Now that her condition has been upgraded from critical to serious, we can focus more of our efforts and care on getting her eating well and regaining muscle mass," said Dr. Lindsay Ruland of EVH. "We expect her condition to continue to improve, but she has a long road to recovery ahead of her and could potentially need further surgeries."

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

"She has remained in good spirits through all of our treatments and even wags her tail now when she goes out for walks," said Dr. Ruland. "We at EVH fell blessed to be caring for such an amazing little girl."

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