A trilogy is a set of 3 works of art that are connected, commonly found in literature, films and video games. They are connected by characters, settings or theme.
In my veterinary example, the 3 old dogs have swellings below the right eye seen by me within a short period of time.
Case 1. A 15-year-old Cross-bred had facial cysts.
Case 2. A 15-year-old Jack Russell had carnaissal tooth abscess and oronasal fistula.
Case 3. A 11-year-old Jack Russell had chronic dacryocytitis
All 3 with different causes but the same surgical outcomes. They have recovered as at Nov 17, 2014
