The Long-Haired Weimaraner, a distinctive variant of the "Grey Ghost," represents a fascinating example of genetic inheritance in purebred dogs. First documented in 1934 at a Vienna show, this variety emerged from the same noble German hunting lineage as its short-haired counterpart. Distinguished by its 2-5 cm long coat with feathering on legs and tail, the long-haired variant results from a recessive gene requiring both parents to carry the trait. While recognized in most countries worldwide, it remains unacknowledged by the American Kennel Club. These elegant dogs maintain identical physical proportions and temperament to standard Weimaraners, excelling both as family companions and working dogs.
Long Hair Gene in Weimaraners
Genetics and Expression
The long hair trait in Weimaraners is controlled by the FGF5 gene and is a recessive genetic trait, requiring both parents to carry the gene for offspring to express the long hair phenotype. According to genetic studies, the inheritance follows Mendelian patterns where:
- LL = Smooth coat (dominant)
- Ll = Smooth coat carrier
- ll = Long hair expression
Historical Recognition
The first documented long-haired Weimaraner appeared in 1934 at a show in Vienna. While recognized in most countries, the American Kennel Club does not currently accept the long-haired variety as meeting breed standards. In contrast, European countries like Germany have fully embraced both coat varieties, with long-haired Weimaraners being equally popular and valued for their enhanced cold weather capabilities.
History and Origins of the Long Hair Weimaraner
Early Development
While the exact ancestry remains debated between bloodhounds and the extinct Grey Saint Louis Hound, the long-haired variety emerged naturally from the original Weimaraner breeding programs in 19th century Germany. Initially bred by German nobility for hunting large game, the breed's purpose evolved to pursuing smaller prey as hunting practices changed.
Foundation Stock in Britain
The British foundation stock originated from three key imports - Asta von Gut Blaustauden (1973), Dino von der Hagardburg, and Hasso von der Hagardburg. A notable milestone was achieved when Sh Ch Pondridge Practical Joker became Britain's first long-haired show champion. The breeding program expanded in 1977 when the Weimaraner Club of Great Britain approved mixing coat varieties, leading to increased genetic diversity while maintaining breed characteristics.

The Long Hair Gene and Inheritance in Weimaraners
Inheritance Patterns and Probability
While previous sections covered basic gene expression, this section focuses specifically on inheritance probabilities. According to genetic research, when breeding:
- Two longhair carriers (Ll x Ll): 25% smooth non-carriers, 50% carriers, 25% longhairs
- Longhair x carrier (ll x Ll): 50% carriers, 50% longhairs
- Two longhairs (ll x ll): 100% longhairs
Gene Expression Mechanics
The dilution gene, which gives Weimaraners their distinctive coloring, works independently from the longhair gene. As documented, the grey appearance comes from banded hairs where the dilution gene affects the spacing between bands rather than the actual hair color. This is separate from the FGF5 gene controlling hair length, allowing both coat varieties to maintain the characteristic Weimaraner coloring.
Health and Genetic Testing for Long Hair Weimaraners
Testing Requirements and Recommendations
While previous genetic sections covered coat inheritance, this section focuses on required health testing. According to genetic screening protocols, all long-haired Weimaraner puppies should undergo:
- Hip and elbow dysplasia testing
- Thyroid evaluation
- Eye examination
- Regular testing for mast cell tumors
Longhair-Specific Health Considerations
The long coat requires additional health monitoring compared to short-haired varieties. Research shows that the longer coat provides better cold weather protection but needs regular inspection for:
- Matting that can lead to skin issues
- Debris trapped in feathered areas
- Ear canal health due to increased hair growth
- Proper airflow to prevent hot spots
Early detection through consistent monitoring helps prevent complications unique to the long-haired variety while maintaining their distinctive coat characteristics.
Conclusion
The long-haired Weimaraner represents a fascinating genetic variant of the traditional breed, controlled by a recessive FGF5 gene that requires both parents to carry the trait for expression. While first documented in 1934 Vienna, these dogs have gained widespread acceptance in European countries but still face limited recognition in venues like the American Kennel Club. The inheritance patterns follow clear Mendelian genetics, with specific probabilities for coat type expression depending on parent genotypes.
This research highlights several key implications for breeders and owners. The long coat provides enhanced cold weather protection but requires additional health monitoring and grooming attention compared to short-haired varieties. Proper genetic testing remains crucial, not only for coat inheritance but also for common health concerns like hip dysplasia and thyroid issues. The successful integration of long-haired Weimaraners in European breeding programs demonstrates that maintaining breed standards while embracing coat variety is both possible and beneficial for genetic diversity.
