Attention: some attachments have red circles for areas that need particular attention before submission!
Your dog is required to have a permanent ID in form of a tattoo or microchip plus should have a registration number through AKC or FCI.
DNA testing for carrier status of vWD and ENM
(turn around time <2 months; no age restriction as long as the dog is big enough for the blood draw, for example at age 8 weeks)

Attachment 4 guidelines:
Instructions for your veterinarian(s):
Minimum health tests for a Kooikerhondje that might be bred include the following:
- A DNA test for von Willebrand Disease and Hereditary Necrotizing Myelopathy (ENM). Ideally 4 cc’s (at least 1cc) of blood should be collected in an EDTA tube and mixed. The sample needs to be sent for testing to the Veterinary University of Utrecht in The Netherlands. At the current time, please do not encourage testing within the USA. Ideally, the sample should be sent through your office (ideally with tracking number) but the owner can also be the one sending it overseas. Make sure that the microchip number is noted on the vial (besides name, DOB, date of collection).
- Patella exam at or after the dog is 12 months old with OFA paperwork submitted to the OFA. Make sure to check the box to agree to have the results published regardless of the outcome of the test.
- A OFA eye exam at or after the dog is 12 months old and prior to breeding if the last exam was done > 2 years ago. A Kooikerhondje is sensitive to touch and might react unpredictable with dilation of the eye and in a dark environment.
- An OFA hip exam for dysplasia at or after the dog is 24 months old with OFA paperwork submitted to the OFA. A Kooiker is a sensitive dog to voice and touch. It is always ideal to do a hip exam without sedation. However, a Kooiker might be fearful and bite.
The dog owner should be encouraged to report health test results and litter updates to the Dutch Kooikerhondje Club (VHNK). They can do so on their own or send the information to:
