The Belgian Kennel Club states the original Belgian Mastiff may be extinct. The FCI placed the breed on the suspended list.  However, there is a workgroup in Belgian re-creating the breed from the breed's standard. There is a breeder in Belgium who succeeded to re-create the breed, and his "master" dog named "Bacon" has already been shown at several dog shows and received excellent ratings. When this has passed all the different committees, it will enter into a 10 year FCI "stage" period. The Belgian Mastiff was used for guard work and for tracking, search and rescue. It is said that he most likely originated in France because of his resemblance to the French hounds. Later his characteristics were changed when he was exported to Belgium. The breed was used for carting in Belgium but the original dogs had become extinct as cart pulling dogs were no longer necessary with the development of the automobile.
