Proper training for aggressive dogs is necessary if your dog is showing aggressive tendencies. In such case, you should deal with the situation right away avoiding safety risks that can arise if your dog attacks another dog or worse, if the problem escalates to an attack of an adult or a child.
The truth is that much of this situation can be avoided if the dog receives adequate training when she is a pup which can help to minimize or eliminate any aggressive displays. An important rule is that a dog must never be allowed, even from a young age, to bite or nip your hands or feet, or even your socks.
One of the best things you can do for your puppy, aggressive or not, is to take her to puppy training classes and to practice obedience at home as well. In general, most puppies undergo a time of socialization, where their social skills become crystallized. This period lasts till they are around six months of age. Most of your puppy’s behavioral concepts will be finalized in this period so if you’re going to teach your dog how to behave, this is the time to do it.
According to most dog trainers, socializing your puppy with other dogs and humans is an absolute must. Chances are, if your puppy learns not to attack or engage in play nipping with other dogs and humans before the age of six months then she’ll probably never do it as an adult dog.
Another thing that you can do when training your dog against aggression is to avoid playing rough games, such as tug of war, with her. If your play roughly, your dog may come to understand that aggressive behavior is perfectly acceptable to you.
