It’s a dog-eat-dog world out there. In the wild, dogs have to protect their territory from other animals and fight for food. The same is true of domesticated dogs that live in houses with humans. These 20 breeds are known as aggressive dog breeds because they were bred to be loyal guardians and protectors who would attack anyone who threatened their family or property. They’re a perfect choice if you want an animal companion who will take care of your home when you can’t be there!

Here are 20 of the most dangerous breeds.

1. Staffordshire Bull Terrier

The Staffordshire bull terrier is a medium-sized, short and sturdy dog. It was originally bred in England for fighting other dogs on pit bulls. Other names include the English Staffordshire terrier, pit bull terrier (not to be confused with an American Pit Bull Terrier), or just Staffy. These are some of the most aggressive dog breeds, and they’re banned in the UK.

The Staffy has a broad head with short front legs that are wide apart, which gives it an intimidating appearance. It’s got powerful jaws that can deliver very strong grips on bones or toys for chewing. Its tough muzzle is useful for holding onto objects firmly to keep them from being taken away. Breeders have been trying to breed out the aggression in Staffies, but some of them still retain a strong prey drive and will chase after small animals or children.

2. Bullmastiff
