What protective feature is missing in the Weimaraner's short, sleek coat?

Answer

Insulating undercoat

The Weimaraner possesses a coat that is exceptionally short, dense, and smooth, which contributes to its racy, streamlined appearance and offers minimal resistance to water. Due to this construction, the coat lacks the necessary insulating undercoat that many other breeds possess. This absence means the dog has very little natural protection against severe cold or rain, often necessitating external coverings for comfort during outdoor activities in harsh weather.
