How to Stop Dog on Dog Aggression
Training, Tips and Advice

Dog on dog aggression training encompasses management and behavioral modification programs crafted for owners of dogs suffering from inter-dog aggression.

Inter-dog aggression takes place when a dog displays aggression towards unfamiliar dogs or other dogs within the household.

While occasionally such agonistic behaviors are considered normal, it is abnormal when excessive and repeated aggressive behaviors are exhibited towards other dogs.

There are several causes for inter-dog aggression in canines; therefore, identifying the culprit is key so to find the most suitable dog on dog aggression training program.

Understanding Dog on Dog Aggression in Dogs

Normally, dogs try to avoid conflicts by engaging in ritualized aggression. Ritualized aggression encompasses a variety of social signals meant to diffuse the real aggression. Posturing, barking, growling and snapping are all ways dogs demonstrate a conflict but without making contact or causing serious injuries.

Unfortunately, there are cases where actual violence takes place among canines, often leading to serious and even fatal results.

Many times, dog aggression problems arise in multi-dog households once dogs reach social maturity which generally takes place between 18 to 36 months of age. It is not uncommon for two dogs of the same sex to get along for quite some time until around 2 years of age.

Dogs reacting to stranger dogs, on the other hand, are often reacting due to dominance or fear; however, many other predisposing factors are at play when dealing with inter-dog aggressive displays and attacks.

The Inter-Dog Aggression Candidate

Any dog may develop aggressive tendencies under the right circumstances, but some dogs are more predisposed than others to inter-dog aggression. For example, intact dogs are more likely to exhibit aggressive behaviors linked to dominance, territory, and protective behaviors.

It is also in the breed standard for certain dog breeds to demonstrate confrontational behavior towards dogs of the same sex. Certain small dog breeds may also suffer from "small dog syndrome" also known as "Napoleon Complex".

Among multi-dog households, it is quite easy for a fight to ensue over resources. Toys, food or attention from the owner may spike an altercation among pack members.

Puppy aggression is often seen in sibling rivalry when litter mates live together and are allowed to bond too much. This may lead to potential fights once the puppies reach puberty.

Fearful and timid dogs, on the other hand, may be prone to defensive aggression and this may be genetic at times.

Finally, dogs equipped with a strong predatory drive may attack smaller dogs that trigger a chase response.

Causes of Inter-Dog Aggression

What triggers a dog fight? There are several types of aggression in dogs.

  1. Fearful aggression is often seen in timid, under-socialized dogs with poor social skills who feel the need to "attack before being attacked".
  2. A dog attacking intruder dogs that enter its perceived turf is most likely acting out due to territorial aggression.
  3. Maternal aggression is observed in mother dogs when another dog comes too close to her offspring.
  4. A dog guarding its food and attempting to attack any dog that comes too close is suffering from food aggression.
  5. Dominance aggression takes place when dogs of similar rank fight over social status or when a top ranking dog feels challenged by a lower raking dog.
  6. A dog that feels the need to protect another animal or person from another dog perceived as a threat is resorting to protective aggression.
  7. Sexual aggression is hormone related and mostly seen in intact male dogs. In the case of re-directed aggression an aroused dog may attack another dog just out of pent-up frustration.

Inter-Dog Aggression Management Tips

Because there can be medical causes for aggression in dogs, it is imperative to have a veterinarian assess a dog displaying unusual aggressive behaviors, especially when they appear out of the blue.

With medical problems ruled out, the next step would be to manage the dog's environment as much as possible. If your dog is not getting along with another dog in your pack, muzzles, puppy crates, barriers, fences and training leashes will help keep troublemakers out of harm's way.

If the aggression is addressed towards unknown dogs, such as during walks or at off-leash parks, the dog would have to always be well under control and kept away from trouble. A protective head halter and a muzzle are good management tools to keep on the aggressive dog during walks. Walking the dog at a safe distance from other dogs is also a must to keep everybody safe.
