Science found that pure canine animals can be more vulnerable than mestizos against diseases
Pure breed dogs face major Health risks compared to mestizos. This phenomenon is mainly due to selective breeding, a process that prioritizes specific physical characteristics over the general welfare of the animal. Beauty standards imposed over the years generated a concentration of genes that predispose to various hereditary diseases.
Dr. Ana López, a specialist in genetics and ethology of the UBA, explained that the selection of particular features reduces genetic diversity. The crosses between related individuals increase the probability of transmit recessive mutations responsible for health disorders. This process, known as Endogamous Depression, weakens the immune system and favors the appearance of diseases.

Mestizo and race dogs: differences in health and risk of diseases
Mestizo dogs have a genetic advantage called “hybrid vigor”. Its genetic diversity acts as Natural protectiondiluting the expression of defective genes and strengthening their immune response.
On the other hand, pure races suffer the consequences of a limited genetic pool, which increases its vulnerability to hereditary conditions. Clear examples of this problem are observed in popular races.
French bulldog
They suffer from serious respiratory problems due to their flattened facial structure. Narinas stenosis and elongated soft palate hinder their breathing and expose them to potentially mortal heat blows. Your life expectancy is significantly reduced by these conditions.
Argentine Dogo
Inherited from the English bulldog and the great Danish Arlequin a predisposition to congenital deafness. In addition, their rapid growth and large size make them prone to hip dysplasia and gastric torsion, a surgical emergency that can be fatal. These conditions demonstrate how the search for specific features inadvertently concentrated serious health problems.
In addition, races such as German shepherd and farmer retriever hip and elbow dysplasia suffer, while Cocker Spaniel English develop otic infections and cutaneous allergies frequently. Dalmatians, recognizable for their mottled fur, have a high incidence of congenital deafness and urinary calculations due to their particular uric acid metabolism. The European Veterinarians Federation warned in 2022 about the Welfare problems associated with extreme breeding due to exaggerated morphological featuresa phenomenon that affects most pure races.
