A dog resource guarding against other dogs can escalate quickly if it is ignored or handled the wrong way.
If your puppy or dog freezes, growls, charges, or snaps when another dog comes near food, toys, a bed, or even a specific location in your home, you may be seeing dog-to-dog resource guarding.
This behavior is not uncommon in multi-dog households, especially during adolescence. But it is not something to dismiss as a phase. What looks like a small growl today can become a much bigger problem if anxiety increases and rehearsal continues.
Resource guarding, sometimes called possession aggression, is a dog communicating that something feels valuable and at risk of being lost.
Let’s walk through what resource guarding looks like, why it often appears around adolescence, and what can be done about it.
What Resource Guarding Really Is
There are two forms of resource guarding:
- Guarding against humans
- Guarding against other dogs
In both cases, the dog is communicating something very simple:
“This is valuable to me, and I do not want to lose it.”
When guarding is directed at other dogs, it can be more complex to work through. The presence of another dog adds pressure, speed, and unpredictability to the situation.
The Early Signs Most People Miss
Growling is usually what gets attention.
But resource guarding often begins much more subtly.
Look for:
- A sudden freeze near a resource
- A hard stare while the body remains still
- Tension in posture
- A low growl that escalates
- Charging or body bumping
- Mouthing another dog’s face
When these behaviors are triggered specifically because another dog approaches a particular food item, toy, or location, that is resource guarding.
And it matters.
Why It Often Shows Up Around Six Months
Around five to six months of age, many puppies enter a second fear period.
They may bark at familiar things. They may seem more reactive. Hormones are beginning to shift. Confidence can wobble.
If a puppy is feeling uncertain, it makes sense that they might try to control what feels valuable.
Which is why two priorities become critical:
- Build confidence.
- Prevent rehearsal of guarding behavior.
The Two Worst Responses With Resource Guarding
When resource guarding appears, most people respond in one of two ways.
1. Ignoring It
Hoping the puppy will grow out of it.
Many do not. More often, the behavior escalates.
2. Disciplining It
Correcting or punishing the growl.
Punishing guarding is like pouring gasoline on a fire. If a growl is punished, the warning disappears. The bite may not.
Increased anxiety leads to faster, more intense reactions.
This is not about labeling a puppy as aggressive. It is about recognizing that anxiety and uncertainty are driving the behavior.
What To Do To Handle Resource Guarding
Here is the approach I took when working through this with my own young dog who was resource guarding against another dog in the household. It is the same approach I recommend in multi-dog homes.
1. Change the Environment
Management comes first.
If a puppy guards a bone inside an ex-pen, move the pen against a wall. Cover sides to create a den-like space. Reduce exposure and pressure.
If food on a counter creates tension, manage access.
Management is not giving up. It prevents rehearsal.
2. Start a Journal
Tracking makes patterns visible.
Record:
- Time
- Resource involved
- Which dog was targeted
- What behavior occurred
- What the outcome was
Patterns emerge quickly. Often one dog becomes the primary trigger. Often certain resources are higher risk.
When triggers are clear, they can be managed.
3. Identify and Remove Triggers
If shoes are guarded, put shoes away.
If leashes are guarded, hang them up.
If toys create tension, control access.
The more rehearsal prevented now, the better the future outcome.
4. Supervise and Interrupt Early
Do not wait for escalation.
The freeze is the moment to act.
Have go-to behaviors ready:
- A Hot Zone on a raised dog bed
- A solid recall
- ItsYerChoice for food impulse control
- A retrieve such as “Bring Me”
- A reliable “Out” cue
These behaviors break fixation and give the puppy a safe alternative.
5. Rank Reinforcers Carefully
When guarding is directed at other dogs, using extremely high value food can backfire. It can become something new to guard.
Middle-of-the-road reinforcers often work best in these situations.
6. Counter Condition Under Threshold
Call dogs in calmly. Reinforce everyone. Create neutral, predictable routines around shared space.
Training under threshold can feel boring.
But boring is beautiful when it builds confidence and prevents explosions.
Please Take Aggression Seriously
If you are dealing with escalation, seek help from a Certified Veterinary Behaviorist.
This is not something to experiment with casually. Getting it wrong can have lifelong consequences.
Getting it right can change everything.
It Does Not Have To Be A Lifetime Problem
In my household, multiple Border Collies showed early guarding tendencies.
None grew up to be dangerous adult resource guarders.
Why?
Because the behavior was not ignored.
It was not punished.
It was managed, observed, and reshaped with patience.
Resource guarding in puppies is information. It is not a life sentence.
If You’d Like Some Support
If this feels overwhelming, you are not alone. Resource guarding can feel scary, especially in a multi-dog home. The good news is that with the right foundational skills, things can absolutely improve.
If you would like guidance, you can reach out to the team at:
Use the subject line:

Let them know you’re responding to the resource guarding blog, and they will send you the information you need.
Getting support early can make the process calmer and clearer for both you and your dog. And sometimes just knowing you’re on the right track makes all the difference. 💛
Today I Am Grateful
For the early warning signs our dogs give us.
A growl is communication.
A freeze is communication.
And when we listen instead of react, we have the opportunity to build confidence instead of conflict.
If you are dealing with this, please do not panic. Stay grounded. Stay calm. Get professional help if you need it.
This does not need to become a lifetime problem.
And that is something worth being patient for.
Thank you for this.
I will be taking the above advice and emailing you for additional personal advice.
Thanks again
I have a dog boutique. I cant bring my dog to work as she guards everything in the shop against people and dogs! She’s fine everywhere else, and even right outside the shop door there’s no problem
But inside…..
its such a pity as Id love to bring her to work
Ive tried introducing her to the dogs and people, having them give her postives, treats or words, making her a private space etc but nothing works.
My dog’s resource guarding isn’t food or toys…it’s me and it’s against other dogs and people. How do I get her to understand she doesn’t need to nip at my grandkids when they give me hugs, or bite other dogs when they come up to me for a pet?
Thank you for this!
Very helpful.
