The breed is calm and good-natured, friendly with people it knows but watchful and self-assured with strangers, and it keeps a guarding instinct. Unlike the Great Dane, which despite its English name was developed in Germany, the Broholmer is a native Danish mastiff, and it is regarded in Denmark as a national breed.
It is a heavy, powerful mastiff, slightly longer than it is tall, with a broad, massive head, a fairly short muzzle and loose skin at the throat. The coat is short and close with a dense undercoat. Recognised colours are light or dark yellowish gold, usually with a black mask, or solid black. Small white markings on the chest and feet are permitted.
The Broholmer's later history is one of decline and careful rebuilding. Away from the great estates, dogs of this type were kept in the nineteenth century by butchers and cattle dealers in Danish towns, who used them to guard their premises and to help handle livestock, and they became known as butchers' dogs. As this work disappeared, the dogs grew scarce. The modern revival worked from the few surviving dogs of the old type and bred to a standard drawn from old descriptions and pictures.
