Great Swiss Mountain Dog
The Great Swiss Mountain Dog is the largest of the Swiss mountain dogs: a short-coated, tricolour working dog with a friendly, confident character. It is a loyal watchdog and family dog, but matures slowly and needs firm training.
Health
These examinations come from the official breeding programme for the breed Grote Zwitserse Sennenhond by Dierenwelzijn Vlaanderen (Animal Welfare Flanders). They apply to the puppies’ parents.
In short
Both parents must have 5 examinations:
- 1 DNA test
- 3 X-ray examinations
- 1 eye 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.

A breeding programme reduces the risk of hereditary conditions, but does not offer a 100% health guarantee.

Considerations when buying
According to the breeding programme approved by Dierenwelzijn Vlaanderen, these examinations must be carried out on both parent dogs: Elbow dysplasia (ED), Hip dysplasia (HD), Bleeding disorder (RPD), Shoulder dysplasia (SD) and 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 Great Swiss Mountain Dog needs varied daily walks and a job, such as draught work or tracking. Its short coat needs a weekly brush and more during moulting.
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
This large working dog is friendly and watchful, and matures slowly. Given its size and strength, it must learn as a puppy to walk nicely on the lead. Bear in mind the space and costs of a very large dog.
