How to Help Dogs Get Along Again After a Fight (From a Chicago Dog Trainer)
When your dogs fight, it’s terrifying. There’s the noise, the chaos, the fear that it could happen again. As a certified dog trainer (CPDT-KA) here in Chicago, I’ve helped a lot of families through that moment — the shock, the guilt, the “what now?” feeling.
The truth is, not all fights are the same. Some dogs can learn to live peacefully again. Others may always need management or professional support. The key is understanding what happened, why it happened, and how to move forward safely.
Every Fight Is Different
Dog fights aren’t one-size-fits-all. A brief scuffle between friends over a dropped treat is a very different situation than a full-on attack that causes puncture wounds. Before trying to reintroduce dogs, it’s important to assess the severity and context of the fight.
Ask yourself these important questions:
Were there any injuries?
Did one dog seem intent on doing harm, or was it a quick, loud disagreement?
Was there a clear trigger — food, toys, people, tension building over time?
If there were injuries, sustained fights, or a pattern of tension, it’s time to pause any direct interaction and get professional help before trying again. That’s not failure — that’s being responsible.
What to Do Right After a Fight
First, separate safely. Don’t grab collars. Instead, use gates, doors, or objects to create space. Once everyone is apart, take a breath. Check both dogs for injuries, and check yourself too.
After a fight, dogs’ adrenaline stays high. Give them up to 72 hours to calm down in their separate spaces. Keep routines normal but quiet. No scolding, no dramatic energy — just calm, predictable structure.
Pro Tip: Don’t try to “make them be friends again” too soon. They need emotional distance as much as physical space.
Why Dogs Fight in the First Place
Dogs rarely fight “out of nowhere.” Often, tension builds up over days or weeks — maybe around resources, space, or attention. Pain and medical issues can also play a role.
Common triggers include:
Food or toy guarding
Redirected frustration (like barking at another dog, then turning on a housemate)
Overstimulation during play
Fear or insecurity
Understanding why the fight happened helps you decide whether it’s fixable at home or needs a behavior professional’s eye.
How to Reintroduce Dogs After a Fight (If It’s Safe)
If there were no major injuries and both dogs seem relaxed around the house (in separate spaces), you can start a very gradual reintroduction. Think of it like reintroducing roommates after a big argument — only with teeth involved.
The goal isn’t to make them best friends again overnight. It’s to rebuild trust and predictability so that each dog feels safe in the other’s presence.
1. Start with Distance and Calm
Begin with parallel walks, where each dog has their own handler. Walk in the same general direction but keep enough distance so neither dog reacts or fixates.
If one dog tenses, stares, or refuses to move, you’re too close. Add distance until both dogs can sniff the ground, take treats, or look relaxed.
Don’t rush this! Calm body language (loose tails, soft eyes, relaxed mouths) is what you’re waiting for. After successfully seeing this for a few walks, that’s your green light to keep progressing.
2. Visual Access Without Contact
After several calm parallel walks, you can begin to let the dogs see each other safely through a barrier — like a sturdy baby gate, exercise pen, or crate. The goal here isn’t for them to interact; it’s simply to observe each other calmly from a safe distance.
You can use treats during this step to help each dog form a positive association with seeing the other. When one dog looks at the other and stays relaxed (even for a second) calmly praise and give them a treat. Over time, they’ll start to connect “seeing that other dog” with “good things happen.”
Just make sure to feed the treats well away from the barrier, not directly in front of it. That way, there’s no competition, frustration, or resource guarding. The goal is calm coexistence, not forced friendliness.
Position the dogs so there’s at least a few feet of space between them and the barrier — far enough that neither can reach through or make contact. No nose-to-nose greetings, no sniffing or touching through the gate.
Watch for relaxed signals: soft eyes, loose tails, normal breathing. If either dog stiffens, stares, barks, or lunges, calmly increase distance and give everyone a break. That just tells you they need a little more time before trying again.
Trainer Tip: Keep sessions short and end on a positive note. “Boring” and “calm” are exactly what you’re looking for at this stage.
3. Calm Indoor Coexistence (Together, But Apart)
Once both dogs can look at each other calmly through a barrier, you can move to controlled indoor coexistence — where they share space safely but don’t have direct contact.
Set up a relaxed, neutral environment like your living room, and tether each dog at a safe distance using sturdy leashes clipped to secure points or heavy furniture. You want them to be able to see each other, but not reach one another.
Give each dog something to do — a chew, a stuffed Kong, or a simple scatter of treats on their own mat. This helps them learn that good things happen when the other dog is around and that they can relax without having to engage.
During these sessions:
Keep things low-key. You can watch TV, read, or chat — normal household energy helps them learn that being near each other isn’t a big deal.
Watch for relaxed body language:
Loose postures, slow blinking, sighing, lying down.
Keep these hang sessions short to start and always end before tension builds.
If either dog fixates, stiffens, or starts to vocalize…
Calmly redirect with distance and take a break. Super important: If this happens, no corrections & no scolding. Your pup is just giving information that they’re not ready for that level yet.
Trainer Tip: Think of this as “parallel living.” The dogs aren’t friends yet, they’re simply coexisting peacefully in the same environment. That’s progress.
When they can relax in the same room multiple times in a row, you can slowly decrease distance or remove one tether under supervision. But don’t rush it — calm repetition is what rewires those emotional responses after a fight.
4. Supervised Freedom and Short Sessions
Once both dogs can relax around each other while tethered or separated, you can start testing short periods of freedom with structure and supervision.
Think of this as a practice run for real life, not the finish line.
4a. Start in a calm, neutral area of the home
Remove toys, chews, and food bowls — anything that could spark tension. Make sure both dogs have recently exercised or done something mentally engaging so their energy levels are lower.
Keep leashes attached but loose, so you can calmly guide if needed without adding tension. Have a few treats ready (in separate pockets for each dog) to reward calm choices.
Trainer Tip: Your calm energy matters. Move slowly, speak softly, and treat it like background activity — not a “big moment.”
4b. Watch for Green-Light Behaviors
Before you even try untethering, look for these signals that the dogs are truly ready:
They can both lie down and rest in the same room.
They disengage from each other easily when you move around.
They can take treats, stretch and interact with you without tension.
They recover quickly if startled.
If you see those behaviors consistently, it’s okay to drop one leash — but keep sessions short (5–10 minutes max) and stay in the room.
4c. Supervision Doesn’t Mean Hovering — It Means Observing
Your job isn’t to micromanage every move; it’s to watch body language.
Loose, curved movements → good.
Stiff postures, freezing, or hard staring → too much.
If you notice those warning signs, calmly call the dogs apart and reset the environment.
Redirect tension with simple obedience cues, scatter treats away from one another, or take a short break behind gates.
5. Gradually Reintroduce Real-Life Contexts
After multiple calm sessions, you can begin layering in mild triggers one at a time:
Move between rooms together.
Have family members enter and exit.
Add gentle play under close supervision.
If excitement spikes or tension builds, step back to shorter sessions or return to tethered coexistence for a few days.
Remember: It’s totally normal to move back and forth between stages! Think “progress, not perfection.”
& Always End Every Session on a Win
Finish while both dogs are calm — even if that means just five quiet minutes together. Praise, separate, and let everyone decompress in their own space. Ending on success builds the emotional foundation for next time.
Environmental Management Tips
Even if the dogs seem fine, management is key for long-term peace:
Feed separately to prevent food guarding.
Rotate high-value chews or give them only under supervision.
Give each dog dedicated one-on-one time with you.
Maintain predictable routines so everyone knows what to expect.
Consistency is what helps rebuild confidence. Dogs that feel safe and understood are less likely to resort to fighting again.
When to Call a Professional
If you’re doing all this and still see signs of tension — staring, lip licking, growling, freezing — it’s time to pause and bring in help.
Sometimes dogs need a fresh set of eyes (and a solid safety plan) to move forward and some post-fight situations need hands-on help — especially if there were injuries or repeated conflicts. Certified trainers and behavior consultants can help you assess safety, identify triggers, and guide reintroduction plans.
As a CPDT-KA certified dog trainer based in Chicago, I can help navigate everything from mild tension to true multi-dog aggression. Every case is different, but one thing is consistent: with the right support, things can get better.
A professional can also help you decide when it’s time to prioritize management over reconciliation — and that’s okay, too. Sometimes peace means safe separation and structured routines.
Moving Forward in Harmony
Dog fights can feel devastating, but they don’t have to define your home. With patience, structure, and professional help when needed, many dogs can learn to coexist again.
If you’re in the Chicago area and need help rebuilding trust between dogs, I offer free consultations to talk through your situation and create a plan that fits your dogs and your household.
