White said no one likes the idea of euthanizing 20,000 animals a year. "We ought to poll all the vets at the shelter and see how many of them like running a doggie Dachau,” White said, referring to the Nazi concentration camp. "I suspect very few of them do. It’s just a hard job that somebody’s got to do, and it seems to me it just fits more with animals and the zoo.” A zoo spokeswoman said Executive Director Dwight Scott was out of the state and could not be reached for comment. Assistant City Attorney Diane Lewis said there could also be legal hurdles to the idea. The zoo trust was formed with the specific purpose of operating a zoo, not animal welfare. "We’d be happy with having some discussions with the zoo,” Couch said.
