Goals & Purpose

The goals and purposes of this breed standard include: to furnish guidelines for breeders who wish to maintain the quality of their breed and to improve it; to advance this breed to a state of similarity throughout the world; and to act as a guide for judges.

Breeders and judges have the responsibility to avoid any conditions or exaggerations that are detrimental to the health, welfare, essence and soundness of this breed, and must take the responsibility to see that these are not perpetuated.


Any departure from the following should be considered a fault, and the seriousness with which the fault should be regarded should be in exact proportion to its degree and its effect upon the health and welfare of the dog and on the dog’s ability to perform its traditional work.

Mudi History

The Mudi, in all probability, has existed since the 15th to 18th century, initially in 1773, with Comte de Buffon describing a Mudi-like shepherd dog. Continuing in 1815 with Ferenc Pethe in the History of Nature, in 1902 with Lajos Méhely, and in 1912 with Ottó Herman.

The purposeful breeding of this dog is attributed to Hungarian Dr. Dezső Fényes, who obtained some brilliant-haired, erect-eared, highly intelligent, and docile individuals of an unknown breed. He began to breed them and, in 1936, presented the dogs at the breeding animal fair. He submitted the first standard for the breed, and the committee accepted the description using the dog breed name “Mudi.” The Federation Cynologique Internationale (FCI) officially recognized the breed in 1966.

The Mudi was recognized by the United Kennel Club on July 1, 2006.

Plural: Mudi or Mudis (The word Mudik is only used when speaking or writing in Hungarian).

Pronounced: “Moody”
Phonetic and IPA [moo-dee | mōōdē | mu di]

Mudi General Appearance

A medium-sized Hungarian herding dog, purposely bred for work. Overall, a well-muscled, moderate-boned, and firm-bodied dog with spitz-like qualities. When viewed from above, it has a wedge-shaped head that tapers towards the nose, with prick ears and almond-shaped eyes. In profile, the Mudi has a topline that slopes very slightly downward from the withers to the croup, and its length is slightly longer than its height. The coat is short, straight, and smooth on the face and front of the legs, to a lengthier wavy or curly coat on the body.

Mudi Characteristics

The Mudi has a loose-eyed and upright herding style with intense, powerful, dedicated to duty, and excellent work-all-day endurance.


They are inherently courageous, alert, and may be aloof to strangers, producing an outstanding guard, watch, and alarm dog.


Versatile, playful, and obedient, they enthusiastically participate in multiple dog sports and activities.
