It is never too early to start thinking of the steps it takes to become a veterinarian. In high school you should take all the math, chemistry, biology, and physics classes that you can. It could be a good time to start volunteering at a local animal shelter or shadow a vet in your area.
In college you will need to choose a school that offers a pre-vet program, or look at what the prerequisites are to the vet schools you are interested in. Your GPA, animal and clinical experience, Graduate Record Exam (GRE), letters of recommendation, leadership & Communication skills, and co-curricular activities are all factors that are looked at on vet school applications.
Penn State has a great resource on how to prepare for these things!
