The CLONED dogs of war: Russia unveils genetically-enhanced canines which will work with Putin’s Special Forces and were created by scientist attempting to restore woolly mammoths
The notion of cloning special dogs for certain roles is interesting, but it’s very likely to be of dubious practical value. The utility of a dog for sniffing out drugs or explosives comes down to their breed and training, and cloning does frak-all to pass on training for anything more advanced than a flatworm. And if you happen to like a particular breed, there are easier ways than cloning to get more of ’em. A male and a female, some mood lighting and Barry White playing over the kennels PA system would not only be sufficient, it might be argued as being a bit excessive for the goal of getting more of that breed.
And cloning is still a sufficiently new practice that it’s not at all clear than the clones will be as healthy or long-lived as the original.
