I am sorry to hear about Roman! I would consider asking your vet if the area needs a bacterial culture and sensitivity. This is a test that identifies the organism causing the infection and the antibiotics that are best suited to treat the infection. We can sometimes get infections with organisms that are resisitant to the more common bacterias (you may have heard of one called MRSA). So it is a good idea if an infection isn't clearing to do a culture. It is also possible his course of antibiotics wasn't long enough to completely clear the infection. Another possibility would be the presence of a foreign body in skin causing a pocket of infection. If the abscess keeps returning your vet may need to do surgery to open the area and be sure no foreign body (like a splinter or grass awn) is present.
