Department of Animal Science

Companion and Exotic Animal Biology Concentration is a program for students who aspire to work with animals that are companions or provide esthetic value to humans. This program includes the core courses for animal science, minimal management of animals, focus on science, and electives in diverse areas such as zoology or wildlife. This concentration can also be a path for students to prepare for and apply to veterinary college but these requirements are not illustrated below.

Students interested to attend veterinary college must clarify all requirements with advisor or with the college to which they intend to apply.

For requirements to apply for admission into the MSU College of Veterinary Medicine (CVM), visit the web pages for the College of Veterinary Medicine Future Student DVM Program.
