Mayday for Mutts – May 4, 2025

Mayday for Mutts is a special holiday celebrated on the first Sunday of May to spread love and acceptance for mixed-breed dogs. This year it falls on May 4. The day encourages adoption procedures from animal shelters to give more of these adorable animals a home.

History of Mayday for Mutts

The word ‘mutt’ was originally used to refer to half-breed dogs that were born from two different breeds. Today, mutts are more commonly referred to as ‘mixed-breed’ dogs that have no specific breed lineage or background.

The “designer dog” trend began in the late 20th century when breeders began to cross purebred Poodles with other purebred breeds to obtain a dog with the Poodle’s coat and several other desirable characteristics from other breeds.

In 1974, a Hollywood mixed-breed called Benji put mutts on the map. Benji was featured on the big screen and was loved and adored by thousands of people. He was known to be America’s favorite mutt.

The Mixed Breed Dog Clubs of America (M.B.D.C.A.) was founded in 1978 and began holding shows in the same year to include mixed-breed dogs that were excluded by purebred registries.

American Mixed Breed Obedience Registry (AMBOR) was founded in 1983 in New Prague, Minnesota, to provide a competitive venue for dogs not recognized by purebred registries such as the American Kennel Club. At that time, it provided rules under which dogs could compete to earn obedience titles in the same way that most purebred dogs could compete in their purebred clubs.

By 1990, AMBOR had reached an agreement with the Illini Obedience Association, host of the prestigious Gaines obedience trials, to allow AMBOR-registered dogs to participate in these top-level competitions.

In 2006, American Mixed Breed Obedience Registry (AMBOR) became a part of the North American Dog Agility Association (N.A.D.A.C.) and AMBOR’s agility and obedience program remained in place.
