What is the purpose of the dense undercoat beneath the wire topcoat?
Answer
Added insulation and water resistance
The structure of the Wirehaired Vizsla coat involves two distinct layers that work together for maximum functionality in harsh weather. Beneath the primary, harsh topcoat, there should ideally be a dense undercoat present. The specific role of this inner layer is to provide an essential layer of added insulation, which helps the dog retain body heat, and to significantly contribute to overall water resistance, enabling the dog to work effectively in icy water or cold, wet conditions.
