Careers in Psychology?

I'm seriously considering changing my major from a major in Technical Theatre and a minor in Psychology to just a major in Psychology. I'm really interested in Animal Behaviorism. If I change what classes I'm signed up for, I could get my Associates degree in Psych next semester (my school mostly offers two-year degrees). There are places around here where I could get my Bachelors, but it would be a stretch to afford them long enough to graduate (I've got a scholarship that's only good for so many hours of credit, and I've been taking theatre classes).

I talked to my advisor today and she didn't have a lot of advice. She said I'd really need to get a Masters to get a job in Animal Behaviorism, but I'm wondering what there is that I could do with a Bachelors, if anything. I know I could just go to Petco and get a minimum-wage job as an in-store dog trainer, but I'd like to eventually move up from there. I'm very divided about what I want to do right now and I'm just hoping for advice and options.
