As the title says- for my EPQ, I want to write a 5000 word report at the end collating all my research and making an informed judgement based on this. So it cannot be a disease with a known cause or a something that is most likely to be the cause and is almost universally agreed on, but hasn't been fully proven yet.
Also, as I started out wanting to do canine pyometra, is there anything about pyometra which is debatable and inconclusive so far? I was interested in doing the causes but a few vets I asked seemed to all have the same answer for the cause so maybe not.
