Break the fight up quickly and calmly, redirect the dog's attention, take them for a walk together, and don't worry that it's going to happen again. They may or may not fight again, but if worry over it does not become your obsession, you will not be feeding them negative energy that will lead to another fight.
Forgiveness brings stress relief.
Both tended to spend more time together after the conflict regardless of if they had an existing relationship. While it seems dogs do forgive after a fight, there's still a lot more to learn about reconciliation in dogs. In some multi-dog households, it doesn't always work out.
Can dogs live together after fighting? The answer is, most of the time, YES. There are times when dogs may be like an incompatible couple and need to divorce, but in general, there are things you can do to help combative pups get along.
Some have recommended that the dogs not be anywhere near one another for at least 48 hours following the fight, even if they live in the same household, while others recommend that getting a positive interaction between the two animals as soon as possible is the best course of action -- at the end of the day, however, ...
Grudges with other dogs
To them, that other dog = bad news, even if they don't remember exactly why. Your dog isn't actively “holding a grudge” against that other pooch, but they are responding to the negative association that was formed the first time, and strengthened every time since.
Break the fight up quickly and calmly, redirect the dog's attention, take them for a walk together, and don't worry that it's going to happen again. They may or may not fight again, but if worry over it does not become your obsession, you will not be feeding them negative energy that will lead to another fight.
In a real fight, the dogs will target the stomach, throat, and front legs and the victim of the attack will often retaliate by grabbing a hold of the other dog's neck. If your dog is involved in such a fight and receives severe injuries, take him to the vet immediately.
If fighting is severe, dogs should be completely separated until conditioning and other treatment protocols can be put in place. Re-homing should be considered if the aggression poses a significant safety issue.
Dogs use actions called "play bows" to ask other individuals to play and also while they're playing to punctuate play bouts to admit they're wrong and say something like, “Sorry I bit you so hard—this is still play regardless of what I just did.
Even dogs that live together or are related can and will fight. Unfortunately, some fighting dogs will not stop fighting until an injury occurs that results in one dog backing off. However, some triggers are easily identified and can be avoided.
People and dogs can become injured when there's a fight. Also, a dog will remember that he's been attacked. It may be very difficult–if not impossible–for them to get along afterwards.
Pups play fight constantly, even with an older dog. Unless the older dog is showing it needs a time out let them play. If both dogs are adult no you should not allow them to fight. Reinforce the alpha position of the older dog, feed it first while the other dog watches, put on a leash and hold it off.
Punishment should be avoided. The dog-dog relationship will not be improved if you scold, punish or hold down a dog as punishment; in fact you may make it worse by punishing the dog for signaling and communicating their aggressive intentions.
Both animals may suffer injuries, including puncture wounds, lacerations, blood loss, crushing injuries and broken bones. Although fights are not usually to the death, many dogs succumb to their injuries later.
"Dogs often fight over access to a resource that is perceived to be valuable." Some dogs fight when moving through or contained within a tight space or during rough play. This aggression may be excitement-related or related to frustration or fear.
Dogfighting is where dogs who have been bred, conditioned and trained to fight are placed in a pit to fight each other for spectator entertainment and profit. Fights average one to two hours, ending when one of the dogs cannot continue.
In short, the answer is yes, a dog can be traumatised after a dog attack. Alongside the physical scars of the wounds they have gained, the dog may be emotionally scarred from the traumatic event, and you will need to be on the lookout for behaviour that might indicate your dog has been affected in this way.
Let your dogs sniff each other and greet each other normally. Give them positive reinforcement through calm verbal affirmations. After letting them play for a while, put both dogs in a “sit” or “stay”, then let them interact again. Finally, take them on walks together, allowing them to sniff each other along the way.
If the dogs are not showing any negative behaviors, reward them with treats just for seeing each other. For example, when the dog you're walking looks at the other dog, you can say “Good boy!” in a happy, friendly voice and give him a treat. Repeat often.
When dogs (and other animals) play, they apologize and ask for forgiveness. The importance of context—who's interacting with whom, who else is around, and where something is happening—can't be overstated. Trust and cooperation also are involved in reconciliation.
