I have a close family member who is a practicing vet. I can say that the demand for vets isnt amazing depending on where you live, and the real way to make money if you do small animals is to be the owner of your practice. My relative has worked for people who arent even vets but could afford to open the practice, and the pay is less than a PA or at most similar. In addition, things like vet pathology is great, but from what I know the competitiveness of vet residencies is very high.
That being said, I think your job as a vet would be far cooler than that as a PA. My relative does their own anesthesia, surgery, medicine, imaging. Path gets sent out, but otherwise its pretty all inclusive. PAs gross, gross, gross. Although lots of gross things are interesting, doing it all day can be a little mind numbing.
