probably because someone liked the look. Some colors can have health issues attached...or temperament issues even. In the absence of that, and since this breed was not bred for any other purpose than companionship and good looks...it's not horrifying me...esp if it is a natural occurence in the breed requiring no outside breeds added.
The Akita was similar in that ONCE parti colored/pintos were highly prized. Then one day the Japanese decided that they were ugly...and showed a Western influence and did not fit the aesthetic of Japanese art which highly values simplicity of form and color. So they reintroduced Spitz types and bred away from the white markings in excess. Others did not find the markings to be any huge deal and they continued to allow it. The breed was eventually split most places outside the USA.
But the original reason for not allowing a flashy pattern...was hardly a health, temperament, or purpose based one. It always pays to know WHY something was not favored. You may find it was nothing noble...more a tantrum or lost chess game...LOL. In which case...why is their reason for not liking it...more important than someone else's for liking it?
