Most likely cause is the infection from the right 4th carnassial tooth abscess. The wound below the right eye does not heal despite many days of antibiotics. This is an oro-nasal fistula. The carnassial tooth has infected roots, spreading pus to the skin which appears as a non-healing wound.  Tooth extraction is the solution but the dog may die from general anesthesia as he is overweight and get cyanotic in his tongue when stressed.
