When thinking about aggressive dogs, those considered as potentially dangerous in the world immediately come to mind, such as the pit bull, rottweiler or dogo argentino.

However, an investigation showed that the most aggressive dogs in the world do not belong to one of these breeds, but on the contrary, it is a type of pet that at first seems very friendly. The study carried out by experts from the Royal Veterinary College of London concludes that the dogs that show the most aggressiveness are the English cocker spaniels.

Research carried out by veterinarians in the United Kingdom reveals that 4% percent of cocker spaniels are aggressive, a figure that triples and reaches 12% if they have golden fur. If we compare, then, Rottweilers with a terrible reputation only reach 7.46% of specimens that show aggressiveness.

Dr Dan O’Neill, who led the project, told the Daily Mail that “choosing between breeds is one of the biggest concerns owners make when getting a new dog.” “Although not a very aggressive breed, owners should be aware that Cocker Spaniels are more aggressive than other breeds typical of families with children, such as Labrador Retrievers,” O’Neill says.

“Aggression levels in cocker spaniels were higher in male dogs and in golden-colored dogs,” he notes.

Another of the study’s conclusions is that aggressiveness has nothing to do with size. In fact, they point out, Chihuahuas are almost as aggressive as German Shepherds.

The English Cocker Spaniel is a very popular dog throughout Europe. Widespread in numerous homes almost like lap dogs, we must not forget their hunting origin. Without proper education they can develop behavioral problems.

It is a medium-sized dog with a compact appearance. The head is slightly domed, but much less than that of the American Cocker. The eyes are brown, bright and alert expression. The muzzle is square, well defined, with strong jaws and a broad nose. Its long, low-set, hanging ears stand out.

The tail is inserted below the line of the back. Traditionally it has been cut with the excuse of avoiding injuries during hunting. But it is an intervention without veterinary justification that has been increasingly prohibited in more places.

Finally, its hair stands out, long, silky and wavy, with a dense undercoat that serves as protection. This coat comes in various colors, such as orange, various shades of brown, black, reddish, lemon, with or without white.
