i heard a rumour that it was being talked about by the government whether or not to give vets the Dr title.
also at the rvc you can do a Dvetmed, after you've done Bvetmed, not really sure what the course entails, may be just a phd of vet med. But it gives you the Dr title (because its a doctorate).
as i beleive (u may correct me, if i am wrong) medical doctors only have the title doctor, because their degree is a doctorate. this explains why in the US both vets and medics have the Dr title - they both do doctorate degrees of veterinary medicine and medicine respectively.
slightly off topic i kno, but personally i am against honourary doctorates being given out by universities - i feel this undermines ppl who put a lot of hard work in to achieve the title the hard way!
