Free Physical Exam
Pets receive a free physical examination when brought in for spaying or neutering. There is no charge for office calls or follow-up exams.

Why should I spay or neuter my animal?
Spaying and neutering:
  • Prevents needless reproduction and destruction of animals
  • Is the most effective means of preventing pregnancy
  • Eliminates or reduces the attraction of male animals to the female
  • Reduces the male's tendency to fight and the resulting wounds and infection
  • Reduces the possibility of cancer or infection of the reproductive tract
  • Results in a generally healthier, more desirable pet
  • Allows spayed and neutered dogs and cats to be licensed at half the cost of non-spayed or non-neutered animals
