Breeds like pit bulls and rottweilers get a lot of attention as being “aggressive” breeds. In contrast, most people think of small and toy breeds as cute, clownish and harmless, but that is not always true.
Some small breeds have been bred to hunt and kill prey, and others can be aggressive due to fear or inbreeding, and you should take that possibility into account when choosing the right dog for you.
Here is a look at some of the most aggressive small dog breeds.
1. Manchester Terrier
However, like most terriers, the Manchester was bred to hunt vermin, and it was very good at that job thanks to its tenacious and sometimes even aggressive nature.
This terrier has a strong prey drive, which can lead him to be aggressive with smaller animals. He is likely to take off and chase birds, squirrels and other outdoor critters, so keep him leashed outdoors.
The Manchester terrier is not a good choice in a home with small pets like kittens, hamsters and guinea pigs. These pets will not be safe around a dog that was bred to hunt them out and kill them.
The Manchester Terrier is generally not a threat to humans if it is well trained. However, these dogs do need their own space, and can snap at people who refuse to leave them alone when they want some alone time.
As a result, they are not generally recommended for families with very young children. Older kids who can understand when the dog wants to be left alone should not have a problem, however.
