Dangerous dog breeds don't exist. There are dogs that have not been properly trained and socialized, who therefore act aggressively, or those who have actually been trained to be aggressive. In other words, while it may be easy to label an entire breed of dogs as "dangerous" the responsibility lies with the individual dog owner.

Dogs of any breed that are unaltered, especially male dogs, and are not properly trained and responsibly socialized, can act aggressively. Many behavioral problems can be corrected or even avoided entirely through proper training. Well trained dogs will know which behaviors are acceptable and which are not, and will be able to act and react in an acceptable manner. Because you will know that you can trust your dog to act properly, you will be able to give her more freedom.

Dogs are pack animals that rely on a social hierarchy. It is important that you establish yourself as the "Alpha" or leader of the pack. Proper, patient training will help your dog understand that you are in charge, you are to be respected, and you will, in turn, care for him properly. This does not involve shouting at, belittling, or physically abusing the dog! Dominance is taught through patience and respect, not fear. Causing a dog to fear you is one of the sure ways to wind up with an aggressive dog that can be perceived as being dangerous.

Responsible dog ownership begins even before you get a new dog. Researching breeds carefully, considering the home environment, time commitment, and impact on your family, and honestly evaluating whether a dog is really the right pet for you is critically important. Once you have determined that you have the time, space, and energy to commit to raising a dog, carefully consider the best breed for you.

Proper dog training must start with socializing your puppy or new dog as soon as possible. The dog should be exposed to an array of different people and environments, including busy places with a variety of sights, sounds, and smells. This should be done slowly and patiently, in a non-threatening way.

There are literally hundreds of sources of information on proper dog training, from the Internet to your local library or bookstore, to your vet and local dog clubs. Dogs are social animals who long to please their human companions; it just takes time and patience (plus a little know-how) to train them properly. Properly trained dogs with responsible owners are not a danger to anyone.
