Bahn was removed from our breeding program, spayed, and placed in a wonderful pet home after she failed her CERF exam in August 2010 due to a cataract. Cataracts are one of the most common health issues in the German Pinscher and they are commonly diagnosed around 4 years of age at which time most quality GP’s have been bred. As of this date (Nov. 2011) there has not been a genetic marker identified for cataracts in the GP, however there is ongoing research in this field. Until such time that a DNA test is developed for cataracts, it will be the responsiblity of breeders to test their breeding dogs yearly and use good judgment in breeding decisions. We recently imported dogs from lines that are clear of inherited vWD, eye, heart and hip diseases for several generations to use with our lines, which are known cataract carriers. By breeding these imported GP’s with our males, we retain the type and temperament that we feel best fits the GP Standard and increase the percentage of GP’s produced which will be clear of inherited eye disease.

German Pinschers are a healthy, long-lived breed.

The main concerns among GP Breeders are:

*Cataracts – Inheritable that cause vision loss

*Canine Von Willebrand’s disease – inherited blood disorder

*Hip Dysplasia

*Heart conditions

The Canine Health Information Center works with Parent Clubs to determine health screening protocols for each breed. Fortunately the German Pinscher is one of the CHIC breeds. Detailed information regarding the health screening criteria for German Pinschers can be found at this link.

The health screening criteria required to obtain a CHIC number are:

EYES – C.E.R.F. Test

HIPS – O.F.A. or PennHIP Test

vWD – vetGen

DNA Test

The following health exams are recommended but not required by CHIC:

CARDIAC: It is highly recommended that the Cardiac exams are performed by a Veterinary Cardiologist

THYROID: OFA Information on Thyroid Testing can be found at:

*Required for Puppy Icon on GPCA Breeders List

Below are additional DNA Tests which are available for German Pinschers:


D Locus (DNA marker tested – C.22G>A)

Associated with the dilution or lightening effect of the solid colors Black and Brown, with D being the dominant allele, the dd genotype results in the diluted effect.

Possible Genotypes:

DD – does not carry dilute

Dd – dilute carrier

dd – dilute phenotype

D Locus

The D locus is the primary locus associated with diluted pigment, which results in coats that would otherwise be black or brown instead showing up as gray, or blue in the case of black, and pale brown or Isabella in the case of brown. The melanophilin gene has recently been shown to be responsible, but not all of the dilute causing mutations have been identified yet.


B Locus (DNA markers tested – S41C, P345Pel, Q331X)

Associated with the presence of chocolate (also commonly referred to as liver or brown). The bb genotype usually results in a chocolate coat phenotype and liver noses among yellow dogs.

Possible Genotypes:

BB – does not carry brown

Bb – brown carrier

Bb2 – brown carrier

bb – brown phenotype

The B locus is responsible for the presence of brown, chocolate, or liver animals. It is also responsible for nose color. The gene associated with this locus is known as TYRP1. In breeds where the A locus does not come into play, any animal that has at least one B allele (and is not “ee”), will be black in pigmented coat. Those dogs, which have two copies of any of several b alleles will be brown. There are at least three such b alleles. Regardless of other loci, any animal with at least one B allele will have a black nose and pads, while those with any two b alleles will have a liver nose and pads.

This test analyzes whether an animal has 0, 1 or 2 copies of the mutations typically responsible for brown, which is also known in some breeds as liver, chocolate, sedge, and less frequently, red. There are three primary “b” mutations that are responsible for nearly every liver or chocolate dog.
