Got an Aggressive Dog?

Signs You Might Have An Aggressive Dog

There are many signs and symptoms that could mean your dog is aggressive. This can be overcome by a professional trainer if you are unable to do anything about these behaviors. Many of the behavioral signs you will see include excessive barking, growling around food and toys, fearfulness, attacks, and more.

Excessive Barking is one of the major signs of Interdog Aggression . However, some dogs do bark a lot and barking can be overcome. Your dog might bark all night long when it is outside and be causing a disturbance to the neighbors. It might bark throughout the day every time people walk by in the yard also. This is a sign of aggression.

Some dogs with interdog aggression often attempt to protect their own possessions. These possessions might include their food and water and their toys or bones. If you walk near them or pick them up the dog may bark. In most cases, an aggressive dog barks at other dogs in the home that touch their possessions or even children.

Fearfulness is another sign that your dog may have interdog aggression. This occurs when you take your dog for walks or to public parks and your dog is afraid of other people or other dogs. In any new situation your aggressive dog may show that it is afraid.

The result of interdog aggression could be an attack. This is the worst case scenario but it could cause a judge to demand your dog be put down. It is the last thing you want to happen. If you notice signs or symptoms of interdog aggression you should contact a local trainer or your Veterinarian to seek advice to help your dog.



Dog aggression is a term used by dog owners and breeders to describe canine-to-canine antipathy.

Aggression itself is usually defined by canine behaviorists as "the intent to do harm". Many dogs show "displays of aggression" such as barking, growling, or snapping in the air, which are considered distance-increasing actions, those that intend to get the person or dog to move away from the aggressive dog. Some dog-aggressive dogs display aggression that is mainly defensive, and they harm another dog only if they perceive that they have no option. Yet, other dogs may develop dog-aggressive behaviour due to medical reasons, such as hormonal imbalances.

Dog aggression is a common dog behavior, and can be seen in all breeds of dogs, although some dog breeds have a predisposition to display such aggression. The breed standard usually spells out whether dog aggression is common in the breed and to what degree it is allowed. Most of the terrier breeds and the bull breeds are believed to have a higher likelihood of developing dog-aggression upon reaching maturity. Individual dogs may or may not display the level of aggression that their breed standard suggests. It is the owner's responsibility to ensure that these types of dogs are properly socialized and given a proper amount of exercise.

As well as breeding, a dog's experiences may affect his chance of developing dog aggression. A dog that is attacked as a puppy may develop fear-based dog aggression towards all dogs, or perhaps only towards dogs that resemble the dog that attacked him. Although people tend to bring these reactions out of dogs more often than dogs themselves, dogs only pay attention to what their owners allow.

Dogs that display dog-aggressive behaviour do not necessarily show aggressive behaviour towards humans. The two types of aggression are not necessarily related, and do not always occur in the same animal.

Factors contributing aggressive dog behavior

Factors contributing to the likelihood of the development of dog aggression include: Anxiety, fear or phobia Lack of structure Lack of proper exposure to other dogs during the critical socialization period Early imprinting by an aggressive or nervous dam A traumatic experience Territorial behavior Thyroid malfunction or other medical conditions Abuse from owners Medical or physical ailments Breeding and genetic predisposition

Dog aggression manifests at the age of adolescence to social maturity (6 months to 4 years). Warning signs such as fear and/or nervousness around other dogs, displays of aggression only under certain circumstances (while on leash, in the presence of food, in the presence of the owner, etc.), or most commonly, over-the-top play behavior can be seen at any stage of the dog's development. Play behavior such as tackling, chasing, mouthing, nipping, pawing, and wrestling are all normal canine behaviors that serve the evolutionary function of preparing the young dog for later combat and hunting. Young dogs that engage in excessive amounts of these behaviors are much more likely to develop dog aggression as they age.

Dog-dog aggression should not be confused with dog-human aggression (also referred to as "dominance" aggression when directed at the owner).

Many people commonly mistake fear and anxiety-related aggression as "dominance aggression," which is inaccurate. Dominance is rarely the cause of aggressive behaviors in dogs, with fear and anxiety being the greatest cause of both dog and human directed aggression.

Lack of exercise is not a cause of aggressive behavior, although exercise boosts serotonin levels, which offset stress hormones such as cortisol, and can complement a behavior modification program. However, it is a common misbelief that aggressive dogs are "not exercised enough." Many aggressive dogs are exercised regularly.

To stop your dog from displaying aggressive type behavior and also to have proper control over your dog in all circumstances, you may be interested in performing some do-it-yourself dog training. This is the training system I use on my own dogs - "Secrets of a Professional Dog Trainer"
