SEOUL: A South Korean firm is offering to clone pet dogs in cooperation with the scientists who created the world's first cloned canine, the company said on Friday.

Seoul-based RNL Bio said it is already working on its first order from an American woman who wants a clone of her dead pit bull. She was especially attached to it because it saved her life when another dog attacked her and bit off her arm.

The client, Bernann McKunney of California, provided the firm with ear tissue from the dead dog, which she had taken and preserved at a US biotech firm before the dog died 18 months ago, company spokesman Kim Yoon said.
