There are multiple reasons that a dog may exhibit aggression toward family members. The most common causes include conflict aggression, fear-based, defensive aggression, status related aggression, possessive aggression, food guarding aggression and redirected aggression.
If your dog is showing any changes in their behaviour, especially if they have started showing aggression suddenly, you should contact your vet as soon as possible. Aggression tends to get worse over time and can lead to serious injuries to you, your dog or other people and pets so getting help is essential.
The root cause of the aggression. A dog who turns aggressive on her owner is not trying to rule the roost. Usually, she is engaging in resource guarding as a result of insecurity. Once called dominance behavior, this conduct is now referred to as conflict aggression because she's exhibiting inner conflict.
Pit Bull Terriers
Probably the most notorious breed on this list, the pit bull has a reputation for unpredictability and aggression, even against its owner or his family. State and local governments have been vigorous in restricting ownership of this dog with breed-specific legislation.
Aggression in dogs can be due to guarding territory, resources, or a family member; fear; frustration; prey drive; or pain. In all of these situations, a dog may be pushed too far and can transition quickly from reactive, fearful, or guarding behaviors to being aggressive.
The Root of the Behavior
When your dog turns his back to you, he is showing you that he's friendly and trusts you. In the animal world, turning your back to someone puts you in a vulnerable position. Your dog is trusting that you won't attack him from behind.
"The motivation for lots of dog bites is fear," he says. "Others are territorial - if they're guarding something that they highly value, or defending their favourite resting place, their bed... Or if they've learned to defend, say, a dog bowl - that can result in aggression."
It is now widely recognised by animal behavioural specialists that dogs that use aggression towards humans or other dogs are not trying to be 'dominant'. Rather, the aggression is usually the result of social confusion, frustration, fear, anxiety or learning.
If your dog has bitten someone, it's natural to question whether you can ever trust them again. The good news is that in many situations, a dog that's bitten can go on to live a long and happy life with no other incidents.
Straight off the bat you should be correcting your dog's growling and/or snapping with a firm “no” at the onset of the behavior. When he stops growling, reward him with a “good boy”, or in the beginning, a treat if it's handy at the exact moment of training so that he knows what he is being rewarded for.
A different set of chemicals is released when you feel hatred or resentment towards someone and your dog can sense that too! Be careful – if they know you don't like someone, they may try to protect you from them which could result in some bad behavioural changes in your pooch.
Owner-directed aggression is problematic for any dog and owner; it most commonly comes in two forms: a genetic disorder referred to as Rage Syndrome, and a more typical diagnosis called Conflict Aggression.
Yes, humans may have selected – intentionally or unintentionally – puppy eyes and crinkled brows as an adorable feature when breeding domesticated dogs. And dogs now communicate with their owners through facial expressions, sometimes to manipulate us. But there surely is no denying the special bond between us.
It's far more likely that they're either pushing boundaries to see exactly what they can get away with, or that they're seeking a feeling of safety and comfort due to a feeling of insecurity (like if you've introduced a new dog into a household with an established canine presence or even a larger family).
Certain breeds seem more prone to suffer from rage syndrome, including Cocker and Springer Spaniels (hence the once-common terms – Spaniel rage, Cocker rage, and Springer rage), Bernese Mountain Dogs, St. Bernards, Doberman Pinschers, German Shepherds, and Lhasa Apsos.
In recent times, research has shown that: Dogs can recognize emotions in people's facial expressions. They're able to distinguish emotional facial expressions from neutral expressions, and they can tell happy faces from angry ones - just from photos of faces. Dogs can sniff out human emotions by smell alone.
The act of holding a dog down forcibly as a correction is generally called the "dominance down." It is inappropriate, ethologically absurd, and completely counterproductive when interacting with dogs.
Dogs of all sizes and breeds show affection and protectiveness by showing and rubbing their butts on humans. They are all equally likely to display affection through their backside. Your dog putting his butt on you is something you should be happy about! It is their way of showing they love you.
Signaling Stress/Avoidance. Conclusion: If your dog is stressed, she will often look in the opposite direction of the stressor. This can be read as “Avoidance”. If someone invades your dog's personal space, and it makes your dog uneasy, she will use a “Look Away” to communicate that.
Dogs use a foot to bridge the communication gap. Your dog quickly learns that handing you their paw receives a positive reaction. By giving you their paw, oftentimes, they just want a pet.
