I can tell you for my son his 7 year program (he chose to make it 7 years it could be 6 or 8 your choice) has been outstanding. The program guarantees admission to vet school if you keep your GPA above a certain (very reasonable) level and meet some other requirements. You could apply to start vet school as soon as you had a certain number of hours and the prerequisites. He easily had that by his 3rd undergrad year. The way the program works at his school is that he will get his BS when he finished his second year of vet school and then his DVM two years later. I’ll give you pros and cons for his program. In our opinion very few cons. He got an excellent education, feels the vet school is excellent and has great opportunities.
Pros for us:
He knew he was getting into vet school and could enjoy his undergrad without going into vet school burned out.
Left time for other extracurriculars (President of his fraternity for example)
Reduced stress. (Ended up with a 4.0 because he wasn’t stressing over it)
Great early contacts made. Knew many of the vet school faculty starting out.
One year less undergrad tuition.
Didn’t have to take electives or classes he wasn’t interested in. Just took the prerequisites and other classes he enjoyed to fill the necessary electives.
Ability to change your mind and go on to get 4 year degree and not go to vet school.
Cons:
If your grades don’t make it, chose to change majors and you chose to not take all the classes required for the degree it might take more time to graduate.
