The longhair coat was introduced during the development of the Weimaraner breed in the 18th and 19th century. Like all recessives, the longhair trait can disappear for generations only to crop up with a chance mating of carriers. The German Weimaraner Club approved the longhair coat in 1935 and all other countries except the U.S. have followed suite. The German Club noted that certain beneficial traits, linked to the longhair gene, were missing from their shorthairs and needed to be reintroduced for the health and well being of the breed.
The longhair carries an undocked tail. The coat lies flat and smooth with feathering on the ears, tail and legs. Both long and shorthaired pups can be found in the same litter of parents that carry the longhair gene.
