Is this a serious question?
No. No, no no. You cannot transfer from medical school to veterinary school. The curriculums are completely different due to the immense species variation. You guys study humans. We study dogs, cats, horses, cows, pigs, sheep, goats, birds, reptiles, etc...everything BUT humans.
You will have to get significant veterinary experience (shadowing, clinic work, etc. with a variety of species - it is required to apply to almost every vet school), make sure you have completed all the prereq classes, and apply to veterinary school to start as a first year.
