The Durham Region Humane Society has increased a reward for information leading to the arrest of whoever neglected a dog to the point where he was found bleeding from his face and feet.

They've named the four-year-old male Chow "Phoenix," because if he pulls through, he would be like the legendary Phoenix bird that soared up from the ashes.

The reward has increased to $2,500.

The dog was found Sunday night in a backyard in the Courtice area, in what Humane Society and SPCA officials are calling "horrific condition." Officers say the dog was dirty, thin and his fur was matted.

His ears were severely infected and his nails had grown out several centimeters long--so long they had curled into the pads of his feet.

Staff with the Humane Society of Durham Region are trying to nurse the dog back to health.

Anyone with information about the dog is asked to contact the Durham Region Humane Society.
