In the near future the practice of dog breeding could be replaced by dog cloning. The first ever cloned dog, named Snuppy, shows that it is possible to produce a dog that is the genetic twin of another canine. However this process remains very difficult and expensive to carry out.
In theory, cloning would allow people to create a twin of their favourite pet or an exact replica of a breed champion. The two dogs would have the same genes, making them identical in appearance and characteristics, although they would not necessarily have identical markings.
