From New Scientist:
Veterinarians must mention the unmentionable, and confront the issue of people who sexually abuse animals. The call comes from Helen Munro of the Royal School of Veterinary Studies in Edinburgh, UK, in a commentary published in the September issue of The Veterinary Journal (vol 172, p 195).
“The impression is that many continue to think of bestiality as a farmyard activity involving animals sufficiently large enough not to be injured, and therefore not much to worry about,” she writes. “It seems that even in these modern times, the sexual abuse of animals is almost a last taboo, even to the veterinary profession.”
