A dog's carcass is to blame for a massive sewage back up in Provo, Utah authorities say.

Authorities blamed the back-up on the dead dog stuffed down a sewer manhole and then opened a criminal investigation about the incident. They found the dog's owner from an identifying chip implanted in it. The owner says the dog has been missing.

Provo has offered to reimburse homeowners for the cost of hiring professional crews to clean up their houses for a second time since asphalt chunks clogged their sewer line five years ago.According to the Associated Pree, other Provo sewer lines have yielded bowling balls and carpet scraps.

This time crews snaked a high-pressure hose with a spiked end into a manhole to clear the sewer main, dislodging the corpse of the large dog.

"I can't take this anymore. We're going to have to move," Donna Dalebout whose house was filled with sludge into their basement. "It's all the neighbors' sewage coming up here in our basement, just like it did five years ago. I can't take it again. I'm too old for this."
