Over the centuries, by dint of selection and crossbreeding, man has benefited the evolution of the canine species by granting many breeds with varied characteristics that differ both in size and in character. Historically, the notion of race only appeared in the 19th century. However, the fact that we are now confronted with an incredible variety of the species (there are currently more than 300 breeds of dogs) testifies to the extent of human intervention.
In fact, crossbreeding aims to generate breeds of animals with improved physical and psychological qualities. However, it must be admitted that the consequences of these transformations are not always well controlled. In this article, we invite you to discover 4 of the main breeds that have been trafficked by man.
Created during the 18th century in England, The Bull Terrier is a breed of dog resulting from a cross between the English Terrier (white English terrier) and the English Bulldog. It was designed to be a fighting dog, especially to deal with powerful animals like bears and bulls. His athletic abilities earned him a great reputation at the time when dog fighting was still allowed in the United Kingdom.
currently, the Bull Terrier is only bred to give rise to beautiful companion dogs. However, the effects of transformations over the centuries seem to have left significant sequelae (very prominent skull, protruding abdomen, predisposition to many diseases, etc.) on certain individuals specific to the breed.
Appeared in the 20th century, the Basset hound was initially created to be a hunting dog. This course resulting from several crosses between the Saint-Hubert dog and the basset d’Artois and/or that of Normandy was quickly adopted as a pet by many households so that it became very popular in Europe, but also in the United States.
If the crossings made it possible at a certain time to have dogs particularly effective for hunting with hounds, the current basset hounds are lower and slower in their movements. Outside, the structure of their legs and their excessive size expose them to various disorders and abnormalities (joint pain, back problems, infections and others).
The English bulldog is the result of several crosses intended to produce a particularly powerful and aggressive dog breed. The breeders who created the species at the beginning of the 19th century had to have an animal capable of facing bulls in dogfights.
Today, thanks to new crossbreeding, the bulldog has become a pet. The dog seems to have lost all of its fighting past although it has retained its massive build. However, the many transformations that the breed has undergone have caused dogs to present many pathologies: breathing difficulties, stenosis, hypoplasia of the trachea, etc.
Coming from the family of molossers, in particular that of the Bullenbeiser, the Boxer is a breed whose selection has been thought out to give birth to an excellent defense animal.. Nevertheless, the species, through numerous crosses, has evolved into a breed predisposed to serious health problems including cancer.
