Once upon a time, there was a clever dog named Detective Dog. Detective Dog was very famous for helping people find lost things.

One day, a little girl named Emily came to Detective Dog for help. She had lost her favorite teddy bear and was very sad.

Detective Dog knew just what to do. He sniffed the air to catch the teddy bear's scent and followed it through the park.

Detective Dog walked and walked until he found a clue. It was a small piece of teddy bear fur stuck on a tree branch.

With the fur as a clue, Detective Dog continued on his mission. He followed the scent to a big scary cave.

He bravely entered the cave, sniffing and searching in the darkness. And there it was! The missing teddy bear!

Detective Dog brought the teddy bear back to Emily, who was overjoyed. She gave Detective Dog a big hug and said, 'Thank you, Detective Dog!'

From that day on, Detective Dog became even more famous for his incredible detective skills. And he was always there to help anyone in need.
