If your daughter wants to work in a zoo, an Animal Science program might not be the best fit. A lot of Animal Science programs are housed in agricultural colleges and focus heavily on livestock and food animals. Some offer specializations like animal nutrition that could be relevant to zoos, but she may want to explore programs in biology, wildlife biology, or zoology instead.
It can also be helpful to choose a school located near a zoo, so she can gain hands-on experience through volunteering or internships. Since zoos have a limited number of roles that involve direct animal care, another good approach is to work backwards: look at specific zoo jobs that interest her, see what qualifications they require, and then pick a program that aligns with those requirements.
