Have him move out of your way a few times a day. If he is lying down in a hallway, walk through him by gently shuffling your feet until he gets up and moves. The alpha never walks around his littermates. Don't let your dog treat you like a sibling, be the parent.
It's useful to desensitize both dogs to a muzzle over the period you're desensitizing them to each other (in separate sessions), so the first time you're ready for them to actually interact together you can muzzle them and be confident they can't hurt each other.
Give them affection and attention on your terms – Call them to you when you have the time and desire to interact with them. Teaching your dog that you 'own your space' is essential to training your dog to respect you. Give them as much love and affection as you like, just on your terms, not theirs.
Lastly, never punish your dog for aggression. Dogs don't understand punishment and thus are more likely to act out or act more aggressive when punishment is used. Instead, the best way to train away aggressive behavior is to reward good behavior.
You have to stay as calm as you possibly can. Don't: Panic or yell. Panic will do to a fight what gasoline does to fire - intensify it quickly. The slower you move the more clearly you will think and the easier you will “see” the fight and make good decisions.
Therefore, when there is fighting between dogs in a home, it is more likely to be caused by conflict over resources, fear, pain and irritability, redirected aggression, or sociopathic tendencies (in which one or more of the dogs have underdeveloped or insufficient social communication skills).
Eye contact is a show of strength among all creatures. If your dog breaks eye contact, this is a telltale sign of submission. In the wild, alphas put betas and omegas in their place with a decisive stare. If your dog breaks eye contact with you first, this is a dramatic sign of them viewing you as the alpha.
Stress signs to look for include whale eye (when dogs reveal the whites of their eyes), tucked ears, tucked tail, raised hackles, lip-licking, yawning, and panting. Your dog might also avoid eye contact or look away.
Physical punishment should never be a course of action following a puppy or dog bite. Tapping or popping them on the nose can be misunderstood and seen as being playful. This could also encourage more unwanted biting behavior. Hitting a dog, or being too rough with a dog, frequently encourages more biting as well.
2) If the dogs have begun fighting, grab the aggressor by his tail and pull up and backwards. When grabbed by their tail, most dogs will also release a bite grip. Continue moving backwards, pulling the dog by its tail so that he cannot turn around and bite you.
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.
Stay calm, and back away slowly. Instead of screaming, or yelling at the dog, speak to him in a soothing tone as you slowly back away. Don't make direct eye contact. Staring in the eyes of an aggressive dog may prompt him to attack.
Punishment should not be used to correct undesirable behavior. Some pets may see it as a form of reinforcement, while others will become increasingly more fearful or aggressive. Punishment focuses on stopping the undesirable but does not teach what is desirable.
Instead of your dog doing his own thing, he will be watching you and focused on you and what you want him to do. With The Dog Calming Code in place and a solid relationship set up, you'll find your dog is LISTENING to you, wanting to FOLLOW your lead and TAKE DIRECTION.
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.
Your dog will know when you are mad.
Dogs hate to disappoint and can sense the emotions and body language that comes with an upset "parent". When you are upset with your dog and he gives you those "sweet puppy dog eyes" he knows that you are upset and is hoping to change things.
