What is a board-certified Veterinary Internist?

  • A licensed veterinarian who has completed additional intensive training after veterinary school. This training consists of a 1-year internship followed by a 3-year residency program meeting the requirements established by the American College of Veterinary Internal Medicine (ACVIM).
Internal medicine specialists diagnose and treat serious and chronic health problems.

My pet had radiography, does he really need an ultrasound?

An ultrasound is a pain-free, non-invasive procedure to evaluate your pet's internal organs. An ultrasound uses sound waves to display the organs in a real-time moving picture. It allows us to visualize objects or possible abnormalities (such as tumors or fluid) that are unseen by radiographs alone.

We are also able to obtain samples by using the ultrasound to evaluate cells, perform biopsies and/or collect fluids. If a sample is needed, sedation will be required for the safety of the pet and our staff.

Can I be there for my pets' ultrasound?

Abdominal ultrasounds are offered on an outpatient basis. Your pet would be dropped off in the morning for an ultrasound to be performed that day. You will be contacted as soon as your pet is able to be picked up from our hospital. There is no set time or guarantee as to when the ultrasound will be performed.

So your pets need to be seen by a surgeon?

Our veterinary surgeon can consult with you and your pet to determine if surgery is the best option. If so, we help find which surgery is best for your needs and lifestyle. Our goal is to get your pet back to "normal" function after surgery.

We often see specialized cases such as:
  • Traumatic injuries and emergencies
    • broken bones, lacerations, bite wounds, splenectomy- removal of the spleen
  • Orthopedic Surgeries
    • ACL tears, hip surgery, knee surgery, amputations
  • Soft Tissue Surgeries
    • mass removals, abdominal surgeries, cancer, reconstructive surgery- skin grafts

Why can't my regular veterinarian do surgery?

All veterinarians may perform surgery as part of their practice. However, difficult and complex cases may be best managed by a boarded surgeon. We ensure working closely with your private veterinarian for proper communication prior to surgery and for additional post-operative care necessary.
