(Virbac, Inc)  Allerderm Spot-On is a convenient topical therapy for dogs and cats suffering from damaged or compromised skin. Allerderm Spot-On contains a skin lipid complex similar to the lipids found naturally in your pet's skin. The application of Allerderm Spot-On restores the protective barrier of the skin, resulting in increased moisture, less sensitivity and more self-repair. Contains ceramides and fatty acids. For initial use, apply one pipette per week for 4 weeks, or as often as daily in severe cases. Maintain skin with one pipette per month.
