Advanced reproductive medicine and care.

Theriogenology is a specialized field of veterinary medicine focused on all aspects of reproductive health. Our theriogenologist delivers advanced, evidence-based care for both male and female pets – whether or not breeding is a part of your plan.

From managing fertility and pregnancy to treating hormonal and reproductive disorders, we deliver expert guidance and compassionate care.

Reproductive health touches many stages of a pet’s life, from breeding to pregnancy to newborn care. Our theriogenology team combines advanced training with compassionate support to help guide you through these important stages of your pet’s life.

What should I expect at the first appointment?

Your initial visit includes a comprehensive physical exam, as well as a discussion of your pet’s breeding and medical history. We’ll talk through your goals and explain the services or treatments that may best support your pet’s reproductive health.

Because this visit is more in-depth, please plan for a slightly longer appointment than a typical follow-up.
