It took the rescuers two and a half hours to free Dori from her painful, overgrown fur

When people first laid eyes on Dori the dog, they thought she was dead.

So when SPCA officers responded to a call about a “dead dog” at the home of Ronald and Shelley Breier, they were surprised to learn that Dori was still alive – unable to move in the corner of a basement but still breathing, according to WIVB 4 in Buffalo, New York.

“I didn’t know what I was looking at,” said officer Jessica Coughlin. “I thought it was simply a ball of fur. There was no movement. I couldn’t tell if it was an animal, and if so, what kind of animal it was.”

Covered in overgrown fur that painfully pulled on her skin, Dori was in horrible shape – the worse case of matted fur vets from the SPCA in Erie County have ever seen, according to WIVB. It’s unclear just how long she waited for help, but thankfully her rescue was quick.

Dori was rushed to the nearby SPCA facility, where it took two and a half hours to remove four pounds of matted fur from her body. The tiny dog – who was surrendered to the SPCA by her owners – is being treated for a list of health issues, including ear infections, damaged eyes, and broken bones.

While the circumstances of her previous life are dark and disturbing (her owners are facing animal cruelty charges), Dori’s future is bright. Vets tell WIVB that the dog should eventually be available for adoption.
