1. If your dog or cat is undergoing an anesthetic procedure, please withhold food after 8.00 p.m. the evening before surgery; You may leave water available for your pet. If your exotic pet is undergoing an anesthetic procedure, please contact us for instructions appropriate to their specific needs.

You will meet with a technician who will answer any questions you have prior to the procedure, provide you with the admission forms, and obtain your contact information.

Hospital/Surgical Information

Preanesthetic blood work: blood work helps monitor the status of the patient's major organs that help the body metabolize the anesthesia. The blood work also helps determine healing ability, blood clotting ability, and general health status of the patient. This blood work may also be the baseline for your pet by which we can monitor trends throughout their life. 

Pre-anesthetic exam: An exam on your pet will be performed by the surgery doctor prior to any procedure, 

I.V. Catheterization: A small area will be shaved on your pet's leg where the I.V. catheter is inserted to allow fluids to be administered during your pet's procedure.

Surgical Site Preparation: The skin surrounding the surgical area will be shaved and scrubbed to prepare the area. Instruments used during surgical and dental procedures are sterilized prior to each patient.

Anesthesia: The anesthetic protocol used will be customized to your pet's procedure based on your pet's age, medical history, duration of the procedure, and potential level of discomfort associated with the procedure.

Monitoring: All surgical patients are monitored by a technician before, during, and after the procedure. 


The surgery doctor will monitor your pet after the procedure and determine a release time based on this evaluation. A doctor or technician will meet with you at the release appointment, and review the written post-surgical care information.
