Resource guarding is a common behavioural concern reported by dog owners and is one of the most misunderstood areas of canine behaviour. Dogs may display behaviours intended to maintain access to something they consider valuable, including food, objects, spaces, people or other resources.

Historically, resource guarding has often been described using terms such as:

• dominance,
• possessiveness,
• jealousy,
• being “bossy”.

However, modern behavioural understanding recognises that resource guarding is not simply about a dog trying to control humans. It is usually related to the dog’s perception that a valuable resource may be lost, threatened or taken away.

Resource guarding is a form of communication.

The dog is communicating:

• “This is important to me.”
• “I am uncomfortable with this interaction.”
• “I want to maintain access to this resource.”

A key principle is:

Resource guarding is not about ownership in the human sense; it is about the dog’s perception of value and security.

Understanding Resources From the Dog’s Perspective

A resource is anything the dog considers valuable.

Resources may include:

• food,
• treats,
• bones,
• toys,
• resting locations,
• beds,
• people,
• other animals,
• spaces.

Humans and dogs may not always agree about what is valuable.

For example:

A person may consider an old sock worthless.

The dog may consider it highly valuable because of:

• scent,
• texture,
• novelty,
• previous reinforcement history.

Understanding the dog’s perspective is essential when assessing guarding behaviour.

Common Signs of Resource Guarding

Resource guarding exists on a spectrum.

Early communication may include:

• moving away with an item,
• turning the body away,
• eating faster,
• freezing,
• stiffening,
• blocking access,
• watching closely.

More obvious signals may include:

• growling,
• snarling,
• snapping,
• lunging,
• biting.

Early signals are valuable communication and should not be ignored.

Resource Guarding Is Communication

A dog displaying resource guarding is communicating information about its emotional state.

The behaviour may indicate:

• uncertainty,
• fear of losing access,
• previous experiences of items being removed,
• high value placed on the resource.

The dog is not necessarily attempting to challenge humans.

For example:

A dog growling when someone approaches its food bowl may not be thinking:

“I want to be dominant.”

The dog may be communicating:

“I am worried this valuable thing will disappear.”

Common Types of Resource Guarding

Food Guarding

Food is one of the most common resources guarded by dogs.

Signs may include:

• eating rapidly,
• hovering over food,
• freezing when approached,
• growling during meals.

Food guarding may develop due to:

• competition during puppyhood,
• previous food insecurity,
• repeated removal of food,
• individual temperament.

Object Guarding

Dogs may guard:

• toys,
• stolen items,
• household objects,
• bones.

The item’s value is determined by the dog, not the human.

Space Guarding

Dogs may guard:

• beds,
• couches,
• crates,
• resting areas.

A dog may communicate discomfort when approached while resting.

This is particularly important because rest-related interactions may occur when the dog is less prepared for engagement.

Human Guarding

Some dogs may appear to guard access to a particular person.

Examples include:

• blocking another person approaching,
• positioning themselves between people,
• becoming tense during interactions.

This behaviour should not automatically be interpreted as loyalty or protection.

It may involve:

• uncertainty,
• social insecurity,
• learned behaviour,
• fear of losing access.

Why Resource Guarding Develops

Resource guarding may develop through multiple pathways.

Genetics

Some dogs may have inherited tendencies related to:

• caution,
• sensitivity,
• persistence,
• resource motivation.

Early Experiences

Experiences during development may influence guarding behaviour.

Examples include:

• competition between littermates,
• inconsistent access to resources,
• stressful environments.

Learning History

Dogs learn from consequences.

For example:

A dog has a toy.

A person repeatedly takes the toy away.

The dog may learn:

“People approaching means I lose valuable things.”

This may increase concern around people approaching resources.

Previous Loss or Deprivation

Dogs with histories of:

• neglect,
• inconsistent care,
• competition,
• limited access to resources,

may develop stronger concerns about maintaining access.

Resource Guarding and Puppies

Puppies naturally explore the world through their mouths.

They may pick up:

• objects,
• food items,
• household items.

Early experiences influence whether puppies learn that humans approaching resources predicts:

• loss,
• safety,
• positive outcomes.

Teaching puppies appropriate exchanges and positive associations can help develop healthy responses.

Why Taking Things Away Can Make Guarding Worse

A common human response to guarding is to remove the item immediately.

However, repeated removal can unintentionally teach the dog:

“Humans approaching means my valuable item disappears.”

This may increase the perceived need to protect resources.

A more effective approach focuses on teaching:

“Humans approaching can predict positive outcomes.”

Avoiding Punishment-Based Responses

Punishment may increase guarding because it can:

• increase fear,
• reduce trust,
• suppress warning signals,
• increase risk.

For example:

A dog growls.

The growl is punished.

The dog learns that growling is unsafe.

However, the emotional concern remains.

Suppressing communication without addressing the cause may create greater safety concerns.

Supporting Dogs With Resource Guarding

Effective support begins with understanding.

Assessment should consider:

• what resource is involved,
• who the dog guards from,
• where the behaviour occurs,
• how intense the behaviour is,
• whether warning signals occur,
• previous history.

Management Strategies

Management reduces opportunities for conflict while support occurs.

Strategies may include:

• preventing access to unsafe items,
• creating predictable routines,
• avoiding unnecessary challenges,
• providing appropriate resources,
• respecting rest areas.

Management is a safety strategy, not a failure.

Teaching Positive Associations

Behaviour support may involve changing the dog’s emotional response to human approach.

The goal is for the dog to learn:

“Humans approaching resources predict good things.”

This requires:

• gradual progression,
• appropriate distance,
• reinforcement,
• respect for the dog’s communication.

Teaching Exchange Behaviours

Teaching dogs to exchange objects voluntarily can improve safety.

A dog learns:

• giving up an item does not mean permanent loss,
• humans provide alternatives,
• cooperation is rewarding.

This approach is based on communication rather than force.

Children and Resource Guarding

Resource guarding requires particular care around children.

Children may unintentionally:

• approach food,
• remove toys,
• disturb resting dogs,
• attempt to hug or handle dogs.

Children should be taught:

• respect dog boundaries,
• leave dogs alone while eating,
• avoid taking items from dogs,
• seek adult assistance.

Supervision is essential.

Veterinary and Health Considerations

Pain can influence tolerance around resources.

A dog experiencing discomfort may become less tolerant of:

• handling,
• movement,
• people approaching while resting.

Sudden guarding behaviour should consider possible health causes.

Key Practice Principle

Resource guarding is a communication behaviour that provides information about what a dog values and what the dog is concerned about losing.

Dogs displaying resource guarding are not automatically dominant, selfish or dangerous.

Effective support involves:

• understanding the underlying emotion,
• respecting communication,
• managing safety,
• teaching alternative responses,
• building trust.

The goal is not to remove the dog’s ability to communicate.

The goal is to help the dog feel secure enough that guarding is no longer necessary.
