The Appt Notes tab on the pet card will track No Shows, Deleted and Cancelled Appointments. It includes the appointment dates, module, and the dates the appointment was deleted or cancelled.
Open the pet card, under Notes, Appt Notes tab.
You can opt to view just one type of appointment by unchecking the boxes for the others.
For example, if you only want to view Deleted appointments, uncheck the boxes for Cancelled and No Show.
