Never kick at a dog because their common reaction may be to turn and bite your foot. It is understandable that your reaction would be to stop the fight by doing whatever it takes. However, physically intervening in a dog fight puts you at risk for getting bitten.
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.
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.
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.
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.
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.
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, ...
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.
It's normal for puppies and dogs to growl and romp over one another in a mock battle. Most dogs display behaviors that can seem a little aggressive to us, but as long as they are within the boundaries of good fun, it is usually okay (and can help them with socialization skills).
If your pet is breathing heavily, or faster than 40 breaths per minute, or if their gums are pale/blue/purple you should seek emergency veterinary care immediately. If your dog is limping or unable to walk, they need to see an emergency veterinarian. Dogs can be stoic and hide their pain very well.
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.
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.
One of the common ways your dog will try to say sorry is by making “puppy eyes” or tucking its tail between its legs. Avoiding eye contact and lowering their ears are also common ways for dogs to apologize.
This aggression may be excitement-related or related to frustration or fear. Finally, some dogs become frustrated and behave aggressively toward a housemate dog when they cannot access something, such as a person or animal viewed through the window. This is known as redirected aggression.
Dogs are inherently social animals that live well together in groups, but that does not mean that all dogs get along. Most dogs will welcome a new sibling, but it is not always smooth sailing.
Fights can last just a few minutes or several hours. 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.
Since dogs have the ability to sense human emotions, that means they are going to react in a similar emotional way as the energy that is surrounding them. If you are fighting with someone and you are upset, angry, and agitated, your dog will feel similar emotions as well.
Dogs in the same household can become aggressive toward each other for a variety of different reasons. Aggression may be dominance-related, territorial, possessive, or caused by fear/anxiety. Some dogs have “alliance aggression”.
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.
