Mudi dog breed came into being during the 18th to the 19th century from cross breeding Hungarian herding dogs with various prick eared German herding dogs. Because of his courageous disposition, the Mudi is very popular with the shepherds for the use in herding large and difficult livestock. Mudi is even used for the battue of wild boar (driving of game towards hunters by beaters).



Mudi is an excellent guard and companion dog. A dog used for searching out drugs. Watch and alarm dog. Excellent agility dog, lovable house pet. Because of his relatively short coat and his excellent adaptability, it is no problem to keep a Mudi in the house.

Head: The most striking part of the Mudi is undoubtedly his head. To the observer, it should give the impression of an alert, always energetic, cheerful and intelligent animal without any trace of timidity or aggressiveness. The head is wedge-shaped, tapering towards the nose. Skull: Skull and forehead are slightly domed. Occiput not pronounced. Superciliary ridges only slightly developed. Stop: Barely pronounced. Nose: Narrow, rounded at front with moderately wide nostrils. In the colours black, white, fawn and blue-merle, the nose is always black; in the other colours the nose harmonises with the coat colour; e.g. the nose in a brown dog is brown and grey in grey dog. Brown (liver brown) coloured dogs have a brown nose and brown eye rims. Muzzle: Moderately strong. Bridge or nose straight. Lips: Tight-fitting to the teeth. Corner of mouth slightly jagged. The lip pigment corresponds with the pigment of the nose leather. Jaws/Teeth: Complete scissor bite according to the dentition formula. Regular teeth of medium size. Eyes: Narrow, slightly pointed at inner and outer corners, set slightly oblique, thus has a “dare devil” expression. The eyes should be as dark as possible. Only in blue-merle dogs, wall (white or blue) eyes are not faulty. Rims of lids are tight, close-fitting to the eyeball and evenly pigmented. Ears: High set prick ears which are of a reverse V-shape and covered with abundant hair reaching beyond the edges of the external ears. The response of the ears to stimulation is very lively. The dog can turn the ears independently of each other like a radar screen. Ears are approximately 10 to 15 percent longer than their width at the base.
