For a long time in the most different countries of the world there live dogs with the truncated top jaw. It is very probable, that already in Middle Ages English dogs which were used for persecution of various animals had been delivered to Europe. By that time these dogs already had the modified top jaw that gave them advantage over other dogs in durability of catch and made them really effective fighters. Thus, it is impossible to confirm precisely, what breeds became progenitor for bulldogs, in fact, in different countries, on different continents (in Peru in the 12-th century there were the dogs very similar to the French bulldogs), as a result of mutations there appeared brachycephals. They crossed both among themselves and with other breeds.
In general, the modern bulldogs' origin is a mystery. Gradually mankind began more deliberate in breeding, therefore standards of breeds were created giving start to a thoroughbred cultivation. Owing to the standard, it is possible to confirm, that the dog belongs to a certain breed. But we are interested in relatives of the French bulldog which are presented further.

Dogs of our breed are inclined to discipline and always aspire to please the owners. But it does not mean that it is not necessary to be engaged in their education, expecting that a dog will understand everything himself. And if you observe some rules, the process of training and education will bring pleasure to you and your pupil, and the most important, will facilitate a dog's life in this mad world of people.

The subject of this section will be of the most often illnesses of the Frenchies that occur. This does not mean that all bulldogs are amenable to them; just there are characteristic illnesses which can affect representatives of the certain breed rather than the others. And it is better to be aware of them to prevent their development. 
As you already know, the French bulldogs possess rather unusual appearance. A large head with big expressive eyes, the hitched up flattened muzzle, large bat-ears, a short neck, and a dense short trunk. And such charming appearance is very far from original dog forms (compare to a wolf), and can become the reason of some problems. And our task is not to admit this.
