Doctors and veterinarians aren't born knowing all those fifty-dollar-words they use; there are whole books devoted to medical terminology. Most of it is dry, staid lists of words and definitions, but every now and then, a bit of the authors' personality shows through.
In "Bailliere's Comprehensive Veterinary Dictionary" by D. C. Blood and Virginia Studdert, the following entry appears on page 133, right between Brunner's glands and brush border:
"Brunus edwardii: the urban, companion animal bear, much admired for its low food requirements and excellent house training, a high emotional output and complete freedom from disease. Called also Ursus theodorus (USA) and Pooh, Paddington or Brideshead bear (UK)."
(I could add that they may be free from disease, but they do seem to be susceptible to lacerations requiring surgical repair...)
