They may be the same and they will need many more of them. One problem with the dogs is that they also become easily injured (paws) and have to be removed regularly from the search to heal. The building debris causes many problems to both dogs and rescue crews.

I have seen a program in national geography about earthquake rescue in Pakistan. British rescue team has an equipment that could find people in debris by detecting carbon dioxide from people’s breath. (I didn’t how this equipment could separate carbon dioxide we breathe from those in air)
If that equipment could work in Sichuan, it would supply huge help in researching people from debris especially 3 or 4 days after disaster. At that time, we need method or equipment to locate people in deep buried.
