Scout's didn't bleed, they fell off (or he would pull them off). After fish oil, Vit E, niacinimide, and a couple of rounds of tetracycline, his nails gradually improved with just the supplements until only about 1 fell off every year. He was never on prednisone or doxyicillin (sp?). His nails remained soft and gnarly; they grew like crazy so had to be trimmed more often. So yes, the condition lasted forever but grew more easy to manage, with decreasing amounts of meds.
