What is a Mudi dog? A Mudi dog is a breed of sheepdog that originated in Hungary as a working dog. Mudi dogs were first intentionally bred in the 1930s, and they became an official breed in 1936.

Mudi Dog Overview

Mudi dogs have an interesting history and personalities to match. While they are primarily bred as working dogs in Hungary, these adorable pups are becoming popular pets. 

Mudi Origins & History

Mudi dogs originated in Hungary from sheepdogs. Until 1936, these sheepdogs were only classified by size.

In the early 1930s, Dr. Deszö Fényesi began separately breeding smaller sheepdogs and gave the Mudi dog its name.

Like many of Hungary’s breeds, the Mudi dog was almost eliminated during WWII.

In the 1960s, breeders began to reestablish the breed, and by 1966, Dr. Zoltan Balassy created the breed standard to apply for FCI recognition.

The FCI approved the breed standard in 1966, but even today, very few people choose to breed Mudi dogs.

In 2000 a new breed standard was created to allow for new color variations that occur naturally within the breed, and in 2022 the AKC announced the breed’s full recognition.

Mudi Appearance

Mud dogs are small and muscular. They have wedge-shaped heads with pointed ears and long muzzles. They have almond-shaped eyes that are usually dark.

Their faces and the fronts of their legs are covered in short hair, but the rest of the coat is long, wavy, and dense.

Mudi Size

The breed standard for Mudi dogs requires males to be between 16 inches and 18½ inches tall and females to be between 15 inches and 17½ inches tall.

Males should weigh between 24 and 29 pounds, and females should weigh between 18 and 24 pounds.

Mudi Grooming Requirements
