Aggression between dogs in the same household is fairly common. In this post I’ll give you some ideas on what to do if your dogs don’t get along.

Looking at my Instagram feed, you might assume my dogs are best friends and everything in our house is peaceful. That we all get along.

That is not reality.

My dogs are ages 12 years and 2 years. Nearly a generation apart. (June 2018 update: My senior dog Ace has passed away.)

They are on opposite ends of the “spectrum” in so many ways – energy, training, maturity.

My senior dog moves at the pace of a sloth. My adolescent weimaraner … drags me.

Because of their differences, my dogs co-exist, but they rarely do things together. I walk them separately. They don’t play. When I write, they each curl up on a separate dog bed.

So when I see my dogs do something like this, I can’t help but take a picture and post it.

But as anyone with multiple dogs knows, more than likely you’re going to have a few growls, barks and scuffles at some point. Maybe even a few fights.

Dogs are DOGS, and sometimes dogs bark, growl and bite.

So if your dogs don’t always get along, know that this is normal.

Sometimes you might have a more serious issue, and in that case I would recommend working with a trainer.

More often than not, it simply comes down to management and making smart decisions.

I know my dogs will fight over rawhides, Kongs, bully sticks or food, for example. So I don’t give them the opportunity.

They eat in separate areas and they enjoy their “goodies” in separate rooms. That is what works for us.

Here are some common “high valued” resources that could trigger a fight between some dogs:

High-value resources for dogs

  • Bones, Kongs, rawhides, bully sticks
  • Food, food bowls or water bowls
  • Dog beds or kennels/crates
  • Toys
  • Doorways or other thresholds
  • A favorite person (family member, dog walker, relative, etc.)
  • A spot on the couch or a chair
  • Another dog

Signs of tension or guarding to watch for:

  • Stiff, still posture
  • Lowered head
  • Raised hackles
  • Cold, hard stare
  • Flicking the tongue
  • Raised lips, showing teeth
  • Growling

See my post: Signs of stress in dogs

Note that you have to look at these things in context and know your dogs. Raised hackles does not always mean aggression, for example.

What to do if your dogs don’t get along

1. List out exact “triggers” in detail. Keep notes.

Sometimes you might not know exactly why your dogs are fighting. It helps to take detailed notes on each situation.

Where did the fight occur? What time of day? Who was there? What items were present?

Which dog seemed to “start it” and why? How long did it last?

Write down these details so you can look for patterns and better manage your dogs in the future.

2. Management to keep everyone safe.

Management comes down to preventing opportunities for your dogs to fight.

Once you know what causes problems between your dogs, you can generally prevent most issues.

  • If certain items cause issues between your dogs, you’ll know to pick up toys, food bowls, bones, etc.
  • Using a gate or kennels/crates can also go a long way when you need to keep your dogs separated during meals or other “exciting” situations that can trigger fights.
  • If you notice tension, re-direct one or both dogs with an upbeat “look hear!”, whistling or clicking your tongue

In our house, my dogs will fight over me if I’m sitting on the ground. If your dogs do this, don’t sit on the ground petting one dog unless you tell the other dog to “STAY.” Or, use gates or leashes to manage them.

3. Work with a trainer if you need it.

Usually fights between dogs are over in a second and sound a lot worse than they are.

However, if you are concerned for either dog’s safety or your own safety, it is smart to consult with a trainer.

Even if you know a lot about dog behavior, it’s worth it to get a neutral opinion from someone who can observe you and your dogs.

It’s hard to recognize behaviors from our own dogs because we are biased or emotional.

4. Don’t force interactions.

Dogs don’t have to be best friends. They just need to co-exist.

When we got our weimaraner puppy in 2016, I was planning on taking cute photos of the dogs together the day we got our puppy.

Turns out, my senior dog would snarl at our puppy if they were too close so I didn’t get many pictures of them together at all when Remy was little!

This is just one example of how you have to change plans sometimes to accommodate your dogs’ needs.

Don’t force your dogs beyond their limits, and don’t rush. I have a good example below of a mistake I made that caused a fight between my dogs recently.

Unfortunately, dog fights are often the person’s fault. It all goes back to management, prevention and making smart choices.

5. Walk the dogs together if possible.

Most dogs will get along during a walk, and this is a great way to involve your whole family. The dogs are out doing something fun together with no pressure. They are spending time together in a positive, safe way.

My senior dog can be a complete grouch in the house, but when I take my two dogs outside they get along much better.

They like to follow each other around sniffing the same plants and grassy areas together. When we first got our puppy, this was the best way to let my two dogs interact.

What to do if your dogs don't get along

Other tips and factors:

  • Avoid greeting your dogs excitedly, especially in doorways or tight spaces
  • If a fight breaks out, try to startle the dogs with a loud “hey!” or clap your hands. Or you can try throwing water on them.
  • Separate your dogs when they’re home alone
  • Consider spaying/neutering. This won’t solve your problem but it can help along with training.
  • Don’t allow dogs to excitedly greet visitors together. Too much excitement can sometimes trigger a fight.
  • Don’t allow too much excitement running and playing in the yard together
  • Use a muzzle if needed
  • Some dogs just aren’t a good fit and it might be best to re-home one dog.
  • One dog may be grouchy due to pain
  • Stay calm. Sometimes people trigger tension or aggression by adding too much excitement or tension to the situation
  • Make sure each dog gets plenty of exercise and training

Aggression between dogs in the same household – An example

My senior dog Ace raises his lips and shows teeth whenever Remy the weimaraner tries to curl up next to him.

Remy likes to test Ace’s seriousness by tip-toeing closer and giving him a quick lick to the nose.

Sometimes Ace will give in and let Remy in for a cuddle. Usually they have a harmless “argument” where they bark until Remy walks away. It’s just “talk” and they do this every day.

But last week, I was sitting on the floor petting Ace when this happened.

Anyone reading this will see my obvious mistakes.

Normally Ace would growl, Remy would bark and then walk away. But this time I tried to coax Remy closer.

I caused tension by pushing my dogs too far.

For 3 seconds they got into an actual fight biting at each other until one of them bit ME.

I set them up for the fight to begin with and then I put my hands in the mix.

Do NOT put your hands into a dog fight, people. Doh!

Of course, after this “explosion” my dogs forgot about it instantly as dogs tend to do.

They shook themselves off and within the hour they were curled up TOGETHER on the dog bed like nothing happened.

Dogs …

I wanted to share that story because living with multiple dogs takes some work, and it’s never going to be perfect.

My two guys are very easygoing, and I have a lot of experience managing dogs through fostering and pet sitting. But sometimes I still make mistakes.

I hope this post gives you some ideas for handling your own dogs, and if you need some help from a trainer, don’t hesitate to do so.
