The best way to deal with aggression in a dog is to prune his behaviors early on.  Dogs are predatory animals so it’s only natural that one would show signs of  aggressive behavior even as a puppy. It’s the master’s responsibility to train a dog  to be submissive and obedient. 

A dog will act aggressively on different occasions for various reasons. Among the  most common reasons are: 

  • Fear or insecurity 
  • Protecting his territory 
  • Struggling for dominance 
  • Feeling trapped or threatened 
  • Hunger  
  • Boredom (chasing cars for example) 
  • The dog has been pampered and suddenly his needs or wants arenít being met  to his satisfaction. 

Show your dog who is boss from the very beginning. There must be no doubt in  his mind that your every command is to be obeyed immediately. This will take  dedication and patience to accomplish. A very well trained dog will respond  favorably to his master’s commands even at a distance and without a leash. That  is not to say though that you should ever take your dog out in public without a  leash. Most communities have leash laws and even though you feel that you know  your dog well, he may behave erratically in an unfamiliar situation. 

Once your puppy has been de-wormed and had his shots you’ll do well to  gradually introduce him to other dogs. Remain in control of his actions at all times.  If the other dog becomes aggressive, hold your dog back to teach him not to  respond to provocation. If your dog becomes aggressive you’ll need to take  charge quickly. A stern “no” and short jerk on the leash will send him the message  that this behavior will not be tolerated. 

Another problematic behavior stemming from aggression is chasing cars, people,  cats, other dogs etc. Not only is it unacceptable behavior but chasing has resulted  in the death of untold numbers of family pets. 

Chasing is instinctual, hunting behavior and nearly every dog will chase something  at one time or another. Going against such a deeply ingrained and natural trait is  truly a challenge. Since hunting behavior is necessary for survival in the wild, it is  probably the hardest habit to break in a dog. Even if your dog is obedient at other 

times he may very well ignore your commands and take off after that irresistible  rabbit. 

There’s no way to outrun a dog. He’ll leave you eating his dust every time. So how  can you stop him from exhibiting this aggressive behavior from a distance? The  answer lies in gaining control of his ability to go after what he wants in an enclosed  space. Place a favorite toy or piece of food just out of his reach. Prevent him from  going after it by holding him back with the leash. Tell him to sit and when he obeys  you, shower him with praise. Then offer him the thing that he wants. By repeating  this training you are teaching your dog that he’s not allowed to have anything  without your permission. 

Start your puppy’s training early on and don’t allow aggression to take hold. You’ll  have fewer headaches, passersby will be safe, and your dog will be more likely to  live a few years longer.
