Though many people think that aggression in dogs is mostly breed-specific and can also be improved by behavioral training, it is not as simple as that. Dog aggression can be a result of a lot of other causes - sometimes the owner is the cause!

Contributing Factors to Aggression in Dogs



Dogs that are sick or are in pain tend to turn aggressive. If your dog suddenly becomes aggressive and growls or snaps at you especially while being touched, it may be because he is suffering from some physical ailment that is causing him pain.

Older dogs may also become more aggressive because they have more aches and pains in their bodies. Also their hearing is getting poorer and they can be startled easily. Being aggressive in this case is a way of self-protection.

Senior dogs with cognitive dysfunction may fail to recognize their own family members and friends, and may display aggressive behavior as a result.

Male dogs in heat can also show aggression toward other male dogs. Female dogs with puppies may show what is called "maternal aggression" toward anyone that approaches their puppies.

Poor Nutrition

If a dog is on a poor-quality diet, he may become aggressive because he is not getting the proper nutrition for his brain to function properly.

Lack of Puppyhood Socialization

Undersocialized puppies and those who have had traumatic or fearful experiences during socialization period are more likely to develop fear- and aggression-related behavioral problems when they become adults.


Dogs that have been abused, punished excessively, or neglected in the past also tend to be aggressive. For example, a dog that is always confined and whose owner uses severe punishment can become fearful. Fear in turn can cause aggressive behavior in the dog. In fact, studies1 have proved that socially confrontational and harsh training methods (think "alpha rolls, "scruff shaking", etc.) as well as physical punishment are associated with aggressive responses in dogs.

Sometimes, overly-active children with unpredictable behavior toward the dog may also trigger aggressive responses in the dog.

As well, improper training and inconsistent leadership can lead to dominance-related aggression in dogs. These dogs are always confused about the human-dog relationship and are constantly in a state of insecurity. They do not know who the "pack leader" is and therefore have to be aggressive for self-protection. Usually, the aggressive acts are directed toward one or several family members whom the dog regarded as "low-ranking" members in the pack.

Signs of Aggression in Dogs

  • Excessive barking;
  • Growling, snarling, or snapping at people;
  • Snapping and snarling when petted, groomed, or lifted;
  • Overly protective (of their toys, territories, food, etc.);
  • Chasing and attacking other animals, such as cats or other dogs;
  • Chasing people or threatening to bite.

How to Treat Aggression in Dogs

Have a Medical Check-up

If your dog sudddenly turns aggressive, especially if he starts snarling or growling at you while you are trying to pet or groom him, take him to the vet for a check-up.

As mentioned above, his aggression may be due to pain caused by some sort of physical problems.

Feed the Dog a Healthy Diet

If you have a dog that shows signs of aggression, you should make sure that you are feeding him food that is nutritive and wholesome. Switch to a natural, high-quality pet food if you have not already done so. Or better yet, feed him organic, home-made food, with natural supplements added.

Increased Physical Exercise and Play Time

Sometimes dogs with behavioral problems have too much energy and they also want some badly needed human attention. Regular daily physical exercise and stimulating play time may be helpful in consuming extra cooped-up energy, making them tired and happily content.

Get Proper Training

It is advisable to start a training program with a professional animal behaviorist - for both your dog and you! The behaviorist can help you and your dog define your respective positions as leader-protector (that is you!) and safe-subordinate pack member (your dog). Making your dog realize his position can eliminate his aggression caused by fear and insecurity.

Natural Remedies for Aggression in Dogs

Many natural remedies, such as herbs, flower essences, and essential oils, can calm down an excitable and aggressive dog. These remedies can be used to take the edge off your dog's anger, making him more mellow and secure.

The remedies can be used in conjunction with other treatments mentioned above.


Calming herbs are effective in relaxing an aggressive dog. Try using chamomile or lemon balm. These herbs can lift your dog's mood and make him happier and more secure.

Essential Oils

Alternatively, use the following essential oils to make a blend to calm down your dog.

You need:

  • 1 oz. (30 ml) carrier oil (e.g. olive oil, sweet almond oil, jojoba oil)
  • 3 drops Lavender
  • 2 drops Chamomile, Roman
  • 1 drops Sweet Marjoram

Put 4 to 5 drops of the blend on a bandanna and tie it around your dog's neck. The scent will stay active for around 4 to 5 hours. Repeat once daily until you see an improvement in the dog's behavior.

If your dog lets you, you can also use this blend topically on your dog. Rub a few drops of the essential oil blend between your hands and apply it on the edge of your dog's ears, between the toes, on his inner thighs, or under his "armpits".

Home Care for Aggressive Dogs

If you have an aggressive dog with unpredictable behavior, it is advisable to keep him on a leash at all times, even at home. The leash allows you to have safer and better control over your dog.

Also consider using a muzzle on your dog (especially when going outside or when you have company!).

Until you receive professional help, avoid all interactions that trigger your dog's aggression.

Even if your dog acts aggressively toward you or other family members, do not use physical punishment as this can only aggravate his aggressive behavior. Instead, you may try to:

  • Keep your dog confined in a separate room (especially when you have company or children are present).
  • Remove all objects (such as bones or toys) that your dog may be guarding.
