Lighter hair in the same shade of color as mentioned above can be seen on the muzzle, throat, chest, belly, buttocks, feet and hocks. They have lighter markings on their shoulders, also known as harness markings. Some dogs have white patches which appear, to a small extent, as a narrow blaze, neckstop or slight necklace, as well as having white markings on their fore and hindlegs and on the chest. The maximum is 30% white. Its pointy ears mean that—unlike dog breeds with long, hanging ears—ear problems are rare. This breed does well in hot climates because of its double layer coat, as long as the dog is provided cool shade and water. The breed does not do well in very deep snow because of its short legs.
