As happened with other rural working breeds in this century, the Vallhund, still a common sight in the countryside into the 1920's, greatly diminished in numbers by the 1940's. Largely due to the efforts of Mr. K. G. Zettersten and one or two other individuals, the breed was preserved. A standard was drawn up and in 1943 the breed was recognized by the Swedish Kennel Club. The general appearance of the Swedish Vallhund is of a small, powerful, sturdily built working dog. Its expression is watchful, alert and energetic.
Ears are medium in size, pointed and erect.
The coat is medium length, with a harsh, close topcoat and soft, woolly undercoat. White markings are acceptable but should never exceed one-third of the total color. While the Vallhund resembles the Corgi in having legs that are short in proportion to its body, compared to the Corgi the Vallhund is somewhat longer in leg and shorter-backed. Vallhunds are self-confident dogs, lively and inquisitive. They are agile and fast.
