Oh no, poor Oscar! Unfortunately ear infections can be very hard to treat, and I would recommend having a culture done on his ear. That will tell the vet what bacteria are present in his ear causing the infection, and then can pick an antibiotic to treat. Some dogs are prone to chronic ear infections, and if this continues to be a problem, there is a solution to keep Oscar from ever getting another ear infection. It's a surgery called a total ear canal ablation and bulla osteotomy (TECALBO). While it will cure ear infection forever, it will leave him deaf in that ear. It would be a last resort surgery, but it is something to consider if you keep having problems with ear infections.
