Unfortunately, it is not an isolated incident, and this happens quite often.

Pit Bull


This large and intimidating dog has earned the reputation of a very aggressive and dangerous creature. But it is not surprising because pit bulls are in the top of rating of fighting dog breeds.

The Rottweiler is a dog with well-developed body with very strong jaws. This breed is characterized as courageous, energetic and often impulsive. The main credo of the Rottweiler is to protect, so it is doubtless that they are perfect guards.

Since they are very loyal to its owner and suspicious of any stranger, they are ready to attack immediately if they notice even the slightest threat. As a result, they are responsible for many fatalities. According to the Center for Disease Control and Prevention, these dogs are responsible for almost a half of all dog bites in the United States in the period between 1993 and 1996.

Wolf hybrid


Many modern dog breeds are crossbred with wolves. This mix of a domestic dog with a wild animal and predator led to the appearance of wolf hybrids that often have a very aggressive character and unstable psyche.

As a result, the behaviour of such hybrids is unpredictable and can be extremely dangerous. For these reason, according to the law in some states of the US it is illegal to keep wolf hybrids as house pets.
