Not only is the Shar-Pei one of the rarest breeds of dog in the entire world, but they’re also one of the most aggressive. The Shar-Pei was bred in China, particularly to be an aggressive dogfighter. For anyone who has a Shar-Pei, their aggression should be monitored carefully.
While they may be sweet to their owners, but they can prove to be pretty dangerous towards strangers. Due to their aggressive nature, it is not recommended that these dogs be left alone with small children as they may attack them. Shar Pei’s should constantly be observed to avoid any fatal injuries.
37. Bully Kutta
Mostly popular in Pakistan, the Bully Kutta is also known as the Indian Mastiff. Like many Mastiffs, the Bully Kutta is used as a protection dog. They surely are an intimidating breed.
Their size, strength and trained aggression have made the Bully Kutta one of the most popular watchdog breeds in all of Pakistan. This dog is often warned against being left alone with small animals and children. Its protective drive may work well for protecting territory and adult humans, but there’s always a margin for error.
38. Russian Black Terrier
The Russian Black Terrier has a particularly gruesome past. This is a fairly new breed of dog, having been bred in the 1920s. Another fact is that they hardly shed which is good for those who suffer from allergies. As far as research shows, the Russian Black Terrier is apparently the only dog that has ever been bred specifically to hunt humans.
It was bred in the former Soviet Union as a dog specifically used to keep prison camp detainees in line. Now, the Russian Black Terrier makes a particularly stunning guard dog, though it’s dangerous past should always be kept in mind.
40. Beagle
Most people associate beagles with loud howling, short, friendly dogs. And while a well-trained beagle could be your best friend, the beagle is actually a dog breed that has a high rate of aggression.
Did you know that beagles were originally bred for hunting small game? Because of this, beagles today have a high prey drive and can become excited and aggressive quite easily. This means that small animals and children should be carefully monitored around this kind of dog. Overall, the Beagle is a very friendly and wonderful house pet.
41. Akita
Most people don’t know the difference between the Akita and the Akita Inu – however, the Akita is the American bred version of the Akita Inu. They’re quite similar, but still two distinct breeds of dogs.
The Akita is an incredibly strong-willed, beautiful dog that has been bred for hunting. They are an independent breed and that makes training them particularly difficult. Akitas, when not trained properly, can become aggressive and dangerous towards others.
