For your first visit, allow yourself at least an hour for the consultation.  Please arrive a few minutes before your appointment to allow time to complete some paperwork.  A technician will guide you to an exam room.  A specialist will complete a thorough exam on your pet, review records from your referring veterinarian and discuss treatment options with you. If we can begin diagnostic testing that day, you may need to leave your pet with us for the afternoon.  During the consultation, the doctor will be able to provide you with an estimate for any additional testing or treatment.

In anticipating the possibility of diagnostic testing, we ask that all patients withhold food 12 hours prior to your appointment.

If your pet is diabetic, please check with our receptionist for specific instructions with feeding and medications.

Recheck Appointments

When calling to make a recheck appointment with one of our doctors, it is very important to schedule your appointment about two weeks in advance. This allows us to accommodate your schedule as best as possible. Also, please request to schedule your recheck appointment with the doctor that originally treated your pet.

Practice Hours

Akron Veterinary Internal Medicine and Oncology Practice is open Monday through Friday, from 9 a.m. to 5 p.m.  On weekends, the on-call doctor monitors in-hospital patients.


Visiting hours are 1 p.m.  to 7 p.m. for approximately 30 minutes, once a day. If you wish to talk with a doctor during visitation, please schedule it with the technician in charge of your pet’s care. If you have any concerns while visiting, please inform the technical staff and they will address it with the attending doctor.

Prescription Refills

We are happy to refill your pet’s prescriptions during office hours. We request a 48 hour notice on all refills. If you run out of your medication, we cannot guarantee that they will be filled before your next dose is due.

Medical Boarding

We understand that, due to some of our patients’ medical conditions, it may be best to board them at the hospital. Once we receive permission from your pet’s attending veterinarian, you will need to fill out the forms above and return them to us prior to arrival. Receipt of those forms will allow us to give you an accurate estimate and have everything ready when you arrive.


If your pet is already a patient and you have arranged to drop him/her off in the morning for a procedure, you will need to print and fill out the Drop-Off Form prior to arrival.
