Aggressive small dog breeds
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.The Manchester Terrier is a bright, lively and energetic breed that is usually good with kids. These dogs are very playful and enjoy plenty of exercise.
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.
