One factor that can contribute to the development of atopy in dogs is compromise of the skin barrier - this potentiates the penetration of environmental allergens into the skin. Vitamin D is a hormone that is involved in the epidermal barrier function, modulation of immune responses to allergens, as well as production of antimicrobial peptides (thus influencing bacterial growth on the skin surface).
In a recent Pet Health Pearl we discussed findings of a study that examined the effects of Vitamin D supplementation in dogs with atopic dermatitis. Discussion includes the effects of vitamin D on itching and skin lesion severity scores, recommended monitoring, and precautions when considering vitamin D supplementation. Here's a preview:
