Hi! If you want to stay in Texas, then Texas A&M is of course, THE school to go to! (slight Texas bias here!) Veterinary school is very competitive, so you will want to apply to several. Look at their requirements no later than the end of your Freshman year in college, so you make sure you take all the right classes. Talk to the recruiters, ask them what they are looking for. I would recommend having 3-5 schools in mind.
If this is something you are really interested in, there is an on-line resource I really like. It is the Merck Veterinary Manual. My dog has some issues, so I like to research in it. At the moment we are dealing with dermatological issues. Check it out!
