Dry, flaky skin isn't just a cosmetic concern—it often means your dog's skin is lacking the moisture and natural lipids needed to stay healthy. When the skin becomes dehydrated, dead skin cells build up faster, leading to visible flakes, rough patches, and a dull-looking coat. Cold weather, frequent bathing, low humidity, or harsh grooming products can all strip away the skin's natural moisture, leaving it feeling tight and uncomfortable. Did You Know? Skin cells naturally renew every few weeks. When the skin becomes too dry, this renewal process speeds up, causing excess dead skin cells to shed as the white flakes commonly known as dandruff.
