Your dog certainly has more things to worry about than a few white flakes on his coat. He would probably much rather focus on digging up that bone he buried a few days ago or chasing the neighbor’s cat away from his territory. But those flakes may have you wondering, “Why does my dog have dandruff?”
Most dandruff is little more than dead skin cells that are being shed, and dogs tend to get dandruff just as frequently as humans do. During the winter months when the air is dry and humidity is low, these snowy-looking flakes seem to get worse.
