It's being done in the performance horse industry. They have been more than a few cutting horses cloned in hopes of replicating an outstanding individual. As it would be with the dogs, all of the genetic make up would be the same, but ability is the question. Just because you are a clone does not guarantee the ability possessed will be carried along. Interesting none the least, but is it really worth the trouble? If it's a male, you can damn near have him live forever if you were to store enough semen for your future plans.
