Should I do more in order to get into CSU Fort Collins Veterinary program?

I'm not sure that I understand your question but I CAN tell you that as you're getting your Bachelor's Degree, go ahead and take that time to also do volunteer work and internships at zoos, vet clinics, and animal shelters. They specifically look for that when you apply to get in to DVM school.

Apologies if you have already contacted the CSU office of admissions, http://csu-cvmbs.colostate.edu/dvm-program/Pages/DVM-Application-Procedures.aspx, and spoken to someone there, but they would be the best source of information on what a successful candidate for admission looks like. Also reach out to any recent CSU DVM grads you can find in your area, don't be afraid to call, email, or mail them and respectfully ask for advice. Be sure to ask specific questions, "should I take more math courses or more biology?", as opposed to "what should I do to get into vet school?". Good luck, study and work hard, listen carefully.
