GROOMING/SHOWING TIPS
When preparing the Mudi for the show ring, please remember the Mudi is to be shown in its natural state. The Mudi should be bathed to be clean, its nails should be trimmed and its teeth should be clean. There is to be NO trimming or scissoring to be done on this breed. Please make sure your Mudi is ready for the show ring by practicing with them. Your Mudi should be comfortable being in a close environment with other dogs of all breeds, being touched by a stranger and showing its bite. This is for your dog's benefit as well as the other exhibitors and the judge!
MCA STAND AGAINST CROSSBREEDING
The Mudi Club of America (MCA) is dedicated to the preservation of the purebred Mudi, particularly the breed's unique traits and strong herding ability. The MCA does not condone the crossbreeding of the Mudi with any other breed for any reason. Our club members are proving that the Mudi is successful in any venue, sport or family. The deliberate crossing to another breed is misleading; crossbreeds may be subject to the genetic faults of both breeds, there is no predictability to it's size, shape or coat characteristics and no consistent temperament type. This provides none of the advantages owning a purebred dog has to offer. All club members are expected to embrace and support this policy.
