Tufts University Vet School is not the only University that
use live homeless dogs for studies like these. This is the first
case I've read about that talked of the open objections of some
vet students to this practice. And it was published by a National News group like ABC. Behind the scenes there has been an
ongoing debate for years now between Vets, researchers and
the whole medical community concerning using live animals as
research/study tools for supposed human or animal enrichment.
