Pet dog turns out to be fox

A couple in Guangzhou, Guangdong province were shocked to find that the "dog" which they had decided to adopt was a fox. The man surnamed Huang found the animal sitting outside his house on a rainy day and decided to offer the shivering creature a home. Huang's wife gave the "dog" a bath, but she noticed that the animal's tail was unusually fluffy for a canine. It also had a ferocious-looking set of teeth and a pungent scent that wouldn't go away even after being washed.

A. Outside their house
