Like many other breeds, Weimaraners can gray in the muzzle as they age, but Weims have a unique characteristic that isn’t typical of all breeds. As they age, some are known to get a lighter patch of color between their ears and on the back of their head that might extend over the forehead and lighten until it’s almost white. This is known as a “Grafmar’s Cap,” the name coming from an early and influential kennel. We don’t have permission to use the best picture we found of a Grafmar Cap, but you can see one here. If you have a good photo of a “Grafmar’s Cap,” that you’re willing to let us use here, we’d be grateful and happy to give full credit.
