We have been trying (unsuccessfully) for almost two months to rid our dog of an abscess on her side.
The vet feels it was caused by a foreign object- she has been on two rounds of antibiotics (now on her third.)
The vet lanced it last week, and advised us to rinse it out daily with a syringe- once with Hydrogen Peroxide and once with Betadine.
Another female of ours had an abscess above her eye, and once it popped, everything healed nicely. However, with this female, popping it did not totally solve the problem.
