Dogs are the best loyal animals to humans. Many people would love to own dogs and treat them as family members. But as a pet owner it is your duty to control dog's aggressiveness. Sometimes dogs show sudden aggressiveness towards other animals or humans. Best treatment is socializing your dog to control aggressive dog behavior.
Socialization means, getting your dog accustomed to strangers and other animals. For this you can take your dog to training center. Where in your dog can socialize with other animals and humans freely. If possible take your dog to different places and environments so that he is used to those environments as well.
Many people hesitate to take their dogs to different places. If your dog is not socialized properly, it can become nervous and fearful. Subsequently treat the problem early. You can observe this problem at early age and provide required training at that time only. If you delay the issue, problem may worsen and even proper training at later stages cannot do any justice.
Therefore socialize your dog to control aggressive dog behavior. Train your dog with basic commands like tightening leash, whisper and other visual commands to control aggressiveness.
