Considerations when buying
According to the breeding programme approved by Dierenwelzijn Vlaanderen, these examinations must be carried out on both parent dogs: Hip dysplasia (HD). 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 Spanish Mastiff needs calm daily walks and is happiest with a large, well-fenced garden. Its coat needs a weekly brush.
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 Hip dysplasia (HD)?
- 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?
