What Is a Cloned Dog
A cloned dog is a genetic copy of an existing dog, created using somatic cell nuclear transfer. Scientists take a cell from the original dog and insert it into an enucleated egg, which is then carried by a surrogate mother.
How Cloning Works
The process starts with a tissue sample from the donor dog. The sample is cultured, and a nucleus is transferred into an egg cell. After activation, the embryo is implanted into a surrogate, resulting in a puppy with nearly identical DNA to the original dog.
Cost and Availability
Cloning a dog is expensive, often costing tens of thousands of dollars, and is offered by a limited number of specialized companies. For more details on the process and providers, see the Wikipedia entry on animal cloning: Animal Cloning.
