No, veterinarians are professionals not hourly workers. This means that they work whatever hours are needed to do the job, if they need to work beyond 8 hours a day or 40 hours a week they get no "overtime pay", just their normal salary.
To use the legal terminology, professionals are "exempt" employees meaning their work hours and pay rates are not regulated by law so they get paid a flat rate salary no matter how much or little they must work, while hourly workers and nonprofessional salaried workers are "nonexempt" meaning their work hours and pay rates are regulated by law so they must be paid a higher rate (usually time and one half) for any "overtime" work beyond 8 hours a day or 40 hours a week.
Most veterinarians do work more than 40 hours in a week - they have to be available for all appointments throughout the day, as well as emergency calls and weekend work. However, depending on the contract the veterinarian signed, the vet may be paid more for the overtime work.
Most veterinarians work a fair amount of overtime, but the pay for doing so varies by clinic. Some veterinarians are paid extra for emergency calls, and veterinarians who are paid on commission will earn extra money based upon the additional clinic income.
Both - some veterinarians work in a clinic (inside) while other veterinarians have an ambulatory clinic and work on the farm (outside).

Most equine veterinarians work on the farms, stables, tracks and show rings where horses are housed at. Some equine veterinarians work in a clinic where horses can be brought for specialized diagnostics and treatment.
Overtime is work done outside your normal daily hours. If you normally work an eight hour day, but work an extra hour one day. That extra hour is overtime, and overtime is often paid at a higher rate.
Veterinarians can work anywhere there are animals.!.!
Private practice veterinarians work as part of a team of people that includes vet techs, vet assistants, receptionists and kennel workers. Also, most veterinarians in the US practice in a multiple-doctor practice, so they also work with other veterinarians.
If you have a union where you work, overtime is often limited for workers in school. If you are being forced to work overtime which is unfair, you should join a union.

You're supposed to be paid more if you work overtime.
