The Wetterhoun is a medium-sized dog, measuring at 55-59 centimeters (21.6-23 inches) at the withers and weighing between 25 and 35 kilos (55 and 77 pounds) at maturity.

[2] Databases are maintained by the Nederlandse Vereniging voor Stabij- en Wetterhounen[5] (The Dutch Club for the Stabij and Wetterhoun) for assessing pedigrees and computing inbreeding coefficients.

Internationally, the breed is recognised by the Fédération Cynologique Internationale in the water dogs section of Group 8.

The Wetterhoun is an excellent gun dog, effectively retrieving across both land and water; however, its strong will and natural guarding abilities make early training imperative.

[6] The breed standard describes the Wetterhoun as reserved, remarking that it is "the ideal guard dog,"[1] despite never being aggressive and enjoying the company of its family.
