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.
First, it's important to realize that the sudden onset of aggressive behavior may not be a sign of a significant personality change. Instead, it usually indicates a developmental stage of a dog's life. Every day, your dog learns new things and responds to new stimuli.
Dogs can become aggressive and bark, growl, lunge at, and even attack other pets and people for all kinds of reasons — dominance, fear, defense of territory, pain, frustration, overly enthusiastic play, and more.
Most scientific studies indicate that it is very possible to rehabilitate a dog after they bite another dog or person.
Stop it or remove your dog from the situation before it escalates. Do not discipline your dog with physical, violent, or aggressive punishments. Opt for positive reinforcement before resorting to the use of aversives. Remember to reward your dog for good behavior.
You should NOT punish a dog for biting. This method may also teach the dog not to give a warning prior to the bite. It certainly doesn't do anything to minimize the dog's stressors.
A dog who suddenly becomes disinterested in his pack may be experiencing a wide range of emotions, such as jealousy, anxiety or depression. Has anything changed in your home environment recently? Maybe someone moved into your home (or out of it). Maybe you've been taking him for walks less often than usual.
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 behavior associated with Rage Syndrome includes outbursts of aggression that are intense and at times unpredictable. These episodes also tend to be large dramatic responses relative to a seemingly benign situation. Affected dogs often freeze, stare, and may rapidly escalate to biting.
Dogs often rely on what I can only call appeals to our sympathy when what they feel threatened by is us. Ignoring or being oblivious to these signals can lead to a bite as directly as pushing forward in the face of growling and snarling can.
Is training an aggressive dog possible? Yes. Aggression in dogs, whether it be toward a dog's owner or other dogs, is a serious behavior that should be adjusted with the help of a professional dog trainer.
If the aggression is motivated by fear, punishment will only make the dog more fearful, and therefore more aggressive. Attempting to punish a pushy or controlling dog is likely to make his behavior even worse. In either case, the dog and owner end up in a vicious cycle of escalating aggression.
Many older dogs show increased aggression, anxiety, or compulsive behaviors. These behaviors are aggravated by body inflammation, sensory changes, and cognitive decline.
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.
Aggressive dogs can certainly be a reflection of their owners, but there are often many other issues that can factor into whether a dog is abnormally aggressive. According to researchers from Michigan State University, dogs with aggressive or anxious temperaments often have owners with negative personality traits.
Some reasons dogs don't come when called include distraction, confusion, or fear. Gradual training and positivity are ways to help build a reliable recall so your dog will come when called.
For example, if a dog doesn't like you, they may find some of your behaviors annoying, especially if you constantly do things that a lot of dogs are known to hate, like getting in their face, hugging them, teasing them, or yelling at them.
Contemporary experts urge against all uses of physical discipline. Tapping or bopping a dog on the nose can be misconstrued as playful behavior, and being too rough with your dog can actually trigger biting, reactive, or defensive behavior.
For a dog who is acting out of fear or frustration (for example, a dog who is barking and lunging on leash), using the word 'no' to stop the behavior without helping to alleviate their fear or frustration will often lead to an escalation in behavior, such as growling, air snapping, or biting.
Act like the alpha of the back and show him who is boss. Look him/her in the eye: When you give a command, look straight at your pet. Make sure he can see that you mean business and that it is not a command to be disobeyed. Always hold eye contact with your pet, no matter how big or small he or she is.
Ignore him for 30 to 60 seconds. If your dog follows you or continues to bite and nip at you, leave the room for 30 to 60 seconds. (Be sure that the room is “dog-proofed” before you leave your dog alone in it. Don't leave him in an area with things he might destroy or things that might hurt him.)
Don't give in to fear or anxiety, and don't start yelling or kicking at the dog. An aggressive dog wants you to be stressed out before it attacks, but if you remain calm and in control, it slows them down and throws them off. Also avoid direct eye contact with an aggressive dog.
