Scientists in South Korea say they have successfully cloned dogs that glow red under ultraviolet light. Not only do they glow red, but they also have a slightly red color on parts of their bodies with thin layers of skin.

Other than the light red tint, the beagles look normal to the naked eye. They seem to act like any other dogs, they just have genes that are a little different. There are a total of six glowing dogs, all named “Ruppy” referring to the combination of the words “ruby” and “puppy.”

While the red glow is an interesting effect for a dog to have, the scientists aren’t stopping there. The idea of the experiment is this will show that genes can be placed into living things to alter their genetics. The possibilities that stem from injectable genes are endless and have the potential to cure some very tough diseases.

The beagles were confirmed to be clones through DNA testing before the glow genes were introduced. Similar experiments have taken place in Europe, but until now, there has only been success with cats, rats and pigs.

The Korean scientists say the research is still under way and refuse to give all of the details of the experiments. It is unknown exactly where the glowing genes came from, but less than a year ago a glowing red fish was discovered that has a strangely similar tint of red when compared to the glowing dogs. There are also species of jellyfish that emit that color light to lure in their prey.
