Saarloos Wolfdog
The Saarloos Wolfdog was developed in the Netherlands from a cross of German Shepherds with a wolf. It looks wolf-like, is reserved and cautious, and strongly attached to its own pack.
Health
These examinations come from the official breeding programme for the breed Saarlooswolfshond by Dierenwelzijn Vlaanderen (Animal Welfare Flanders). They apply to the puppies’ parents.
In short
Both parents must have 5 examinations:
- 3 DNA tests
- 2 X-ray examinations
The breeding programme also recommends 1 further examination.
A sample for DNA tests can be taken either with a mouth swab or by a blood sample. To carry out the examinations, the breeder uses a vet or a laboratory. For each examination below, you can see from what age and how often it must be done. Ask the breeder for the results of both parent dogs.

Considerations when buying
According to the breeding programme approved by Dierenwelzijn Vlaanderen, these examinations must be carried out on both parent dogs: Degenerative myelopathy (DM), Elbow dysplasia (ED), Hip dysplasia (HD), Pituitary dwarfism (PD) and Progressive retinal atrophy (PCYT2). The breeding programme also lists these recommended examinations: Eye disorders. A puppy with a Flemish pedigree comes from parent dogs bred according to this breeding programme. Ask for the results of both parent dogs and compare them with the overview above. A Saarloos Wolfdog needs long daily walks in a quiet setting. Its dense coat needs a weekly brush, much more during the moult.
Questions for the breeder
- Have both parent dogs undergone all the mandatory examinations in the breeding programme, and may I see the results?
- What are the results of both parent dogs for Elbow dysplasia (ED) and Hip dysplasia (HD)?
- Is the general eye examination of both parent dogs still valid? According to the breeding programme: Valid for 2 years.
- Will the puppy receive a Flemish pedigree from a recognised breed registry association?
- How are the puppies socialised before they go to their new home?
Breed-specific challenges
It is shy with strangers and new situations, and needs a lot of patient socialisation. It needs plenty of exercise, a sturdy fence and an experienced owner, and does not like being left alone for long.
