I have to say I agree with the OP. I got my Ph.D. in Animal Sciences from a University with a Vet School. Several of the courses I took were taught over in the Vet School and later I taught in a couple of classes attended by Vet Students. MS and Ph.D. students (ie scientists) are expected (and in turn expect) to learn concepts, apply critical thinking skills, and reason out problems from day one. Vet Students (the AnSci equivalent to Med Students) are expected to memorize facts for 2 to 2.5 years. There is no expectation of critical thinking, no reasoning out complex problems, no application of previously learned concepts to novel situations until year 3 in Vet School.
They are very highly trained, but the training they recieve is very different from the training I recieved. I very quickly started thinking of MD's and DVM's as biological mechanics by default. Nothing I've seen in my interactions with them has led me to believe that I am mistaken to think of the individuals that way until they proove otherwise on a case by case basis.
