I don't see what's so wrong with cloning the dog... He was cloned to replace a lost pet but for scientific purposes and it sounds like he's being well taken care of. Cloning is very important for scientific and medical research.

Now, all the people who are now jumping to clone their pets... personally that just seems kind of weird. After putting my dog Dewey to sleep after only having him for a couple weeks, I started browsing petfinder for a new dog but I immediatly vetoed anything that looked a little like him. To have one that looked exactly like him would just be much too creepy.
