Dalmatians have pigmented spots on their white fur coats because of a genetic trait inherited from their parents. The interaction of three genes – the S (spotting) loci, T (ticking) loci and F (flecking) loci – creates the spotting pattern that’s completely unique to the breed.
A dalmatian puppy is born completely white and the spots develop as they mature, with the first ones appearing within three weeks and more developing throughout their lives at a slower rate. The spots are usually black or brown, varying in size and number. Dalmatians even have spots inside their mouths!
