FOKKERSDAG (Breeder's Day) in the Netherlands (above - Intske's litter from Doutzen and Mees) : entire litters aged between 1 and 1.5 years are viewed by a Stabyhoun judge, and a health inventory is completed.

Health testing and reporting plays a key role in breeding decisions.
The Stabyhoun is a relatively healthy breed, despite the small population and the limited number of founder dogs. The breeding requirements of the ASA and the NVSW aim to reduce genetic disorders as much as possible, though there are not tests for every disorder, nor is it always known if a disease is hereditary. The challenge is to use as many healthy dogs as possible to promote genetic variation, while avoiding passing on genetic disorders or poor conformation.
Health problems are recorded in the Zooeasy database and all Stabyhouns get a health survey, as the dogs reach 1 to 1.5 years old.
Hip dysplasia is a developmental disorder of the hip joints caused by both genetic factors and environmental factors. Symptoms include trouble getting up and lameness in the hindquarters. HD can be determined by taking X-rays of the hip joints. HD-A is the best, HD-E the worst.
The breeding policy of NVSW: HD research is required. There may be bred with the results A, B and C, B and C may only be coupled to A or B. With HD D and E may not be bred.
Elbow dysplasia is a collective term for three types of developmental disabilities at the elbow joints, caused by both genetic and environmental factors. Sufferers exhibit lameness in the front legs. ED can be determined by x-ray, carriers can not be identified with it.
The breeding policy of NVSW: ED examination is not mandatory. With proven sufferers and carriers should not be bred (a proven carrier is a dog that has passed the same disease in two different litters). Immediate family members of a patient not be combined with dogs that have sufferers under their direct family members.
In epilepsy occurs suddenly a disturbance in the brains in which a dog loses control over a part of his body: he falls, gets severe cramps, may foam at the mouth and he can run his urine or feces. However, there are also milder forms of expression. Epilepsy can be hereditary but can also be caused by environmental factors. The inherited form usually manifests itself in the Stabij around two years.
The breeding policy of NVSW: preventive examination for carriers is not possible. Proven sufferers and carriers should not be bred (a proven carrier is a dog that has passed the same disease in two different litters). Immediate family members of a patient not be combined with dogs that have sufferers under their direct family members.
PERSISTANT DUCTUS ARTERIOSIS (PDA)
A heart condition also called ductus arteriosus. When pupcontrole the veterinarian at the age of 6 to 7 weeks is a loud engine noises "heard on the left side of the heart. Cause it is not close to a major blood vessel surrounding the birth. The cause may be spontaneous and isolated to a single event, but also hereditary. If not treated, the patient dies ultimately to heart failure. By timely intervention surgery, the prognosis is excellent.
The breeding policy of NVSW: preventive examination for carriers is not possible. With proven sufferers and carriers should not be bred (a proven carrier is a dog that has passed the same disease in two different litters). Immediate family members of a patient not be combined with dogs that have sufferers under their direct family members.
A hereditary problem that inherits single recessive: only if both parents carry the defective gene can be born sufferers there. Around 6 weeks puppies go deviant and compulsive behavior: keep repeating the same movement, turning in circles, backwards or walking back and forth. Sufferers have an excessive urge to move, eat poorly, wasting strong and death within a few months.
Research has been done into the cause, in collaboration with the University of Utrecht. The mutation has now been found, and there is a DNA-test which can distinguish available free dogs of carriers.
This test is compulsory for breeding animals.
VON WILLEBRANDS DISEASE TYPE 1
VWD is a blood clotting disorder that occurs in three types. In Stabyhouns, Type I, the mildest form has been detected. This causes a reduced production of a particular clotting factor which dogs may show increased bleeding. Owners often do not notice their dog has it and carriers are at little to no risk, but sufferers can have increased bleeding in injuries and problems during surgery. There is a DNA test available that sufferers carriers to identify.
The breeding policy of NVSW: there is no breeding policy for VWD, the DNA test is not mandatory.
