The quoted number is 20% but that is success of each procedure, each of which might involve multiple embryos being implanted. Remember though that dog cloning is working with perfect and complete samples, not degraded DNA from a frozen bog body.
Some service dogs are really unique. I watched a program last evening. A young lady has a condition where she can pass out without warning. This caused her to be house-ridden. She got a dog as a pet and it turns out her dog can sense an oncoming episode and she gets a 5 minute warning. She can now rejoin society. Until the dog dies. A clone and some socialized training with the first dog could enable her to continue being outside the house.
haha, I've been in that situation myself. The replacement was born a couple of years ago, and I'm being forced to change her poop-filled diapers, teach her how to talk..
