You can reduce the risk that your dog will bite, but you need to be aware that there are no guarantees.
 Here are 7 steps to take to minimize the risk: Spay or neuter your dog.
This is very important If you do not plan to breed your registered dog.
This procedure will reduce roaming and minimize the desire to be aggressive with other dogs.
You will have an easier time controlling your pet and it will accept confinement better.
Spayed or neutered dogs are much less likely to bite.
Contact your local veterinarian or Animal Control Office about low-cost spay/neuter options for your pet.
Socialize your dog.
Introduce your dog to many different types of people (young and old, walking, in wheelchair, on bicycle, male and female, different races, etc.
) and situations so that he is calm and relaxed wherever he is.
Take your dog with you when you can focus on your pet's reaction to the environment.
 You should plan outings with your dog for the sole purpose of introducing your pet to new situations, and only when you have control over your dog.
When you have something that occupies your attention and cannot watch your pet, then leave him at home.
Train your dog.
You can, and should, train your dog yourself.
And each member of the family should learn the training techniques and get the dog used to obeying all members of the family.
In addition to your training, enrolling in a training class is an excellent way to socialize him and to learn proper training techniques.
In an organized training setting, you are with other people who also want to socialize their dogs.
Teach your dog appropriate behavior.
Don't play aggressive games with your dog such as wrestling, tug-of-war, or "siccing" your dog on another person or animal.
Set and enforce limits for your dog's behavior before an accident happens.
If he exhibits dangerous behavior, particularly toward children, seek help from a dog trainer (another advantage to enrolling in a organized training class is that you establish contact is a dog trainer), your veterinarian, an animal behaviorist.
If your dog exhibits any of the following behaviors, he poses a significant bite risk and you should consult a professional trainer for advice: · Aggressive behavior toward other animals; · Dominant behavior toward family members including refusal to get off the couch or bed; · Possessive behavior including growling or snapping when you get too close during dinner or when he's playing with his favorite toy; · Biting and growling out of fear; · Territorial aggression such as barking and growling at joggers or bikers when they are in or near his home.
Be a responsible dog owner.
License your dog (if you live in an area that requires licensing) and keep your dog healthy by providing regular veterinary care, including rabies vaccinations.
For everyone's safety, don't allow your dog off his leash or to roam.
Remember, violating leash laws may also subject you to large fines, jail and civil law suits.
Make your dog a member of your family.
Dogs that have been socialized to be relaxed around people and are under leash control rarely bite.
On the other hand, dogs that spend a great deal of time isolated from people by being kept alone in the backyard or tied on a chain often become dangerous.
Chaining or tying a dog encourages aggressive behavior.
In addition, each year, tie-outs account for a significant number of reported deaths of dogs that were unable to reach water or were hanged.
Err on the safe side.
If you don't know how your dog will react to a new situation and you cannot focus on what your dog is doing, leave him at home.
If your dog overreacts to visitors or delivery or service personnel, keep him in another room when they are present.
To overcome this, have a friend pose as a repairman to get your dog calm around strangers in the home.
If you are not confident of his behavior, avoid stressful settings.
