Onyx, the black Labrador Retriever, was forced to stay at the Durham County Animal Shelter for days after biting a little girl.
But Onyx's stay was short-lived.
Somehow Onyx got through three security features and escaped the facility. He was spotted along I-85 in Durham by two Good Samaritans.
"How? I'm just astounded as to how did he get out?" Onyx's owner Loni Waters said. "If he got out, how was he taken care of? Apparently not very well."
Waters said Onyx also returned home with a health problem. He was dehydrated and had a 101 degree fever when he was found along the highway. The dog is now being treated for an upper respiratory infection.
"I'm not paying it. They didn't take care of the dog. I don't know what they did," Waters said.
The shelter said in a statement:
"This situation could have ended very badly. That is why we have taken this entire week to verify that all of our security measures are as strong as they can possibly be."
The shelther also said that respiratory infections are common in kennels and they wish Onyx the best ahead.
The family received a bill for Onyx's stay of $157, but on Thursday the shelter agreed to waive the charges.
The shelter cares for nearly 6,500 animals each year.
