Why do Dogs with Seborrhea have Flaky Skin?
The flakes that we see on dogs with seborrhea are dead scales (dead skin cells). In a normal dog, the cycle of dead cells being replaced by new skin cells is about 3 weeks. In dogs with seborrhea, however, this cycle is greatly accelerated and takes only a few days. As a result, there is an accumulation of dead skin cells on the skin surface.
