Rottweillers

Any breed can be aggressive... Depends on how they are raised, trained and what they were bred for.

dogs arn't aggressive people make them that way...no rotties are real sweeties if you bring them up well..........

No dog breed is truly aggressive , it all depends on the person who owns him or what he has or she has gone in there life. some people say Pitt Bulls but as i said before it depends on you treat them.

Any kind can be aggressive. It's all in how you treat and raise them. I have been around all types of breeds, and none of them have showen any form of aggression. Most people think of Pitbulls being mean, most of them can be babies. If you don't mistreat the dog, or make them mean, they could be the sweatest dog. Like I said, it's all in how you treat and raise them.

Rottweilers can be made to be aggressive. i have a Rottweiler and she is sweetest, smartest dog that I have ever had. My wife even named her "Baby"

There is no dog that is more aggressive than any other. It is all in how they are raised and socialized. The ones most people think of when they think of mean dogs (i.e. rottweillers, pit bulls, dobermans, etc.) are seen as mean because they were trained a lot as guard dogs or fighting dogs. It is hard to believe thirty years ago the english bulldog was one of the most aggressive and sought after fighting dogs in the world and look at them now.

chihuahua ..but nobody cares because they are so small. Go and visit a dog show ...you gonna here the most noise (barking , growling )at the chihuahua ring.
