From Dog

Piedaldism is a coat characteristic of dogs, commonly seen in the Dalmatian and other spotted-coat dogs.

The genetic loci for this coat characteristic is also responsible for ticking and flecking. These distinctive coat patterns are the result of the interaction of several genes. Specifically, it involves a number of alleles - the Piebald allele, the ticked allele and the nonflecked allele of the flecking locus. All these alleles result in pigmented spots on a white background on a dog's coat[2].

The color of the pigmented spots in registered Dalmatians is black or liver, but the locus responsible for the color variation has not been identified in the Dalmatian. Other colors are rare, but can be found[3].
