Spanhanh Anh: the world's worst dog breed?

Dogs with soft ears and this innocent look may be one of the world's most aggressive dogs. A recent study has concluded that British breeds of Spanhon dogs are more hostile than other breeds.

This finding is again a proof that aggressive aggression is a genetic trait, that genes and breeding conditions can determine how a dog behaves.

'In my country, according to the existing database, Spanhon is a dog that has more aggressive temperament problems,' said Marta Amat, the lead author of the study with Discovery News.

Amat, a researcher at the University of Barcelona's School of Veterinary Medicine, and colleagues analyzed 1,040 cases of aggression dogs brought to the regional dog training hospital in 1998-2006. The main cases are Spanhanh Anh, Rottweilers, Boxers, Yorkshire terriers, and German shepherd dogs.

In further analysis of the data, Amat and his team found that the British Spanhon breed tends to react more aggressively to owners and strangers than other breeds. In the British splendor, the golden feathered males are the most hostile.

The findings, published in the latest issue of the Journal of Veterinary Behavior, reaffirmed the results of a previous study conducted by a Spanish scientific group at the University of Cordoba, that the Spanhon males and yellow feathers are more aggressive than females and those with black or multicolored feathers.

In terms of coat color, Amat explained that pigment melanin has the same biological characteristics with dopamine and other chemical components of the brain associated with aggressive temperament.

Amat also noted that 'lack of information about how this animal reacts to unsatisfactory education of dog owners' is also a cause.

Other experts have even more responsibility for dog owners - they think that no dog has an innate bad behavior, only those who do not know how to train.

Joaquin Perez-Guisado of Cordoba University is the leading author of one of the earlier studies of the Spanhon British breed, and is the lead author of a new Journal of Animal and Veterinary Advances study. This study shows that poor training farmers will lead to aggressive aggressive behavior of 711 experimental dogs belonging to many different breeds.

Considering all the reasons, he and his research team concluded that 40% of the unusual aggression in dogs is related to the fact that the dog does not train, or training is not enough to obey.

According to Perez-Guisado, the group, 'properly trained dogs usually do not have aggressive temperament.'

Members of the Spanhanh Anh dog club in the US also agree with the statement. They describe their puppies as "a family member" "very affectionate, loyal, and reserved to strangers."
