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).
The fights may start out as snarling and growling over space or other resources. If left unchecked, serious fighting can ensue resulting in injury or even death. Fighting occurs because the dogs have not established a stable dominance hierarchy. Dogs have no sense of equality, so one must always be the leader.
Most dogs assume a neutral or submissive role toward people, but some dogs will challenge their owners for dominance. A dominant dog may stare, bark, growl, snap, or even bite when you give him a command or ask him to give up a toy, treat, or resting place.
Don't physically discipline your dog: You love your pets like family, so you'd never want to hurt your dog. It goes without saying that you should never lay a hand on your dog to discipline him, even if you're extremely frustrated. There is a never a reason to hit, shake or intimidate your dog.
Methods such as alpha rolls and physical corrections (via the leash and a choke chain or by smacking the dog on the nose or by shaking their scruffs) were often recommended as a way for humans to establish dominance over their dogs.
If your dog sees you as the alpha, they will permit you to eat first and refrain from snatching or stealing food. This is a sign of respect. In your home, you set your dog's feeding schedule. If your pup sees you as the alpha, he or she will patiently wait for food or subtly ask for table scraps.
Asserting Dominance
By sitting on people, dogs often feel higher and more in control. If you notice your dog barking or growling at other pets while sitting on your lap, it may be a sign that your dog is feeling the need to assert his dominance.
The safest and most effective way to treat an aggression problem is to implement behavior modification under the guidance of a qualified professional. Modifying a dog's behavior involves rewarding her for good behavior—so you'll likely be more successful if your dog enjoys praise, treats and toys.
For dogs exhibiting territorial aggression, you will need to gain enough control to have your dog sit, stay, and when calmed down, take a reward at the front door. Generally, a leash and head collar will give the fastest and most effective control (see Training Products – Head Halter Training).
React promptly
As soon as he does start to display signs of aggression, turn around and pull him away. Walk away from the person or pet until he has fully calmed down. Once he has, you can turn back around and slowly approach again. It may take several attempts before you can get within 10 feet.
This is well-intended but incomplete advice – if you only ignore the behavior, your dog will probably never learn to stop barking, jumping, or pulling. Just ignoring unwanted dog behaviors misses an important piece of teaching your dog what TO do instead. Dogs learn by association.
If you catch your dog or cat engaging in an incorrect behavior, try a loud noise such as clapping your hands or a loud “no”. Remember, reprimands need to occur while the behavior is happening, preferably just as it begins, and never after.
So, Will My Dog Forgive Me For Hitting Him? Dogs are capable of forgiveness, but it may take some time and effort to rebuild trust and repair the relationship. Show your dog love and kindness, and consider seeking the help of a professional trainer or behaviorist if you are struggling with training or behavior issues.
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.
Dogs, like people, respond best to positive reinforcement. Trying to curb your dog's more aggressive behaviors by rewarding only positive behaviors can help train those aggressive instincts away. If he is calm for a while or behaves well during an encounter with guests or other dogs, reward him with a treat.
There are also a couple of smaller things you can do to show your dominance and act like an Alpha. Something as simple as not walking around your dog is enough. If your dog is blocking the hallway, make them get up and move. Simple shuffle your feet or make some noise to let them know you're trying to get through.
Socially dominant individuals commonly display behavioral traits like aggression, physical exclusion, and coercion, and these traits may define socially dominant individuals (5–9).
