Do vet contained by the UK return with the title "Doctor"?

Answers:

I don't know about present times, but in the wonderful series, All Creatures Great and Small, the vets be addressed as Mr. Herriott or Mr. Farnon.

No. Veterinarians in the UK are awarded a bachelor's degree surrounded by veterinary science. Therefore, they are not doctors like those in the US that earn first a bachelor's degree and next a doctor of veterinary medicine degree.
