I should be the one say sorry for misunderstanding.
Thank you for your correction.
I saw some dogs were used by fireman or rescue personnel in TV. Is that different? Or is that dog, canine, especially useful for earthquake?
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.
