Understanding resource guarding in dogs is important for every dog owner. This behavior, where a dog aggressively protects food, toys, or even people, often stems from instinct and anxiety. It's a natural canine behavior but can escalate into a concerning issue if not managed properly. Recognizing the signs of resource guarding, such as a growl, stiffening posture, or even a bite, is the first step toward addressing it. This article aims to educate you on resource-guarding behavior, offering insights into prevention and management.

What is Resource Guarding in Dogs?

Resource guarding in dogs is a behavior where a dog exhibits signs of possessive aggression over valuable items. This could include food, toys, or even their favorite human.

This instinctual behavior can range from subtle actions, such as stiffening or avoiding interaction, to more overt signs like aggressive postures or vocalizations. The guarding can occur against various perceived threats, including both familiar and unfamiliar people or animals.

Despite domestication, dogs may still display these guarding behaviors, a throwback to their days as scavengers, where guarding food from other members of their group was imperative for survival.

What are the Signs of Resource Guarding in Dogs?

It is important to be able to recognize the signs of resource guarding in dogs as the earlier it is addressed, the better the prognosis.

Key indicators of resource guarding in dogs involve body language and behavioral changes. Signs include:

  • Body Language Changes: Dogs may exhibit a change in body posture when they are guarding. This includes stiffening of the body, a head lowered below the topline, ears flattening, and tail positioning – either down or raised above the topline. Piloerection (raised hair along the back) can also be a sign.
  • Facial Expressions: Look for raised lips, bared teeth, or a hard stare. These expressions indicate a dog's discomfort and readiness to defend its resource.
  • Vocalizations: Growling, barking, and snarling are common vocal signs of resource guarding. These sounds are a clear warning that the dog feels threatened and is prepared to escalate its response if necessary.
  • Guarding Actions: A dog might hover over or physically block access to guarded items.
  • Aggressive Reactions: In more severe cases, the guarding behavior escalates to snapping, lunging, or even biting. This level of aggression typically indicates a high level of distress or fear related to the guarded resource.
  • Eating Habits: A dog might eat more rapidly when guarding food. This behavior stems from an instinctual fear of having the food taken away.

What are the Causes and Triggers of Resource Guarding?

Resource guarding in dogs can be attributed to a variety of factors. Understanding these underlying causes and triggers is important for proper management and prevention:

  • Early Experiences: Puppies competing for resources with littermates or dogs that have faced scarcity or neglect may develop resource-guarding behaviors.
  • Environmental Influences: A dog's living environment, including competition for resources with other pets or negative experiences, can contribute to resource guarding.
  • Learned Behavior: Dogs may learn to guard resources if they find this behavior effectively protects their valued items.
  • Fear or Anxiety: Often a response to perceived threats, anxious or fearful dogs may resort to resource guarding as a safety mechanism.
  • Lack of Confidence: Dogs that lack confidence might feel the need to guard resources more aggressively as a way to assert control over their environment.
  • Absence of Routine and Structure: A lack of consistent routine and structure can lead to feelings of insecurity in dogs, prompting resource-guarding behaviors.
  • Previous Experiences of Being Punished or Challenged: Dogs that have been punished or challenged for guarding behaviors in the past may develop more intense guarding as a defensive reaction.
  • Change in Household Dynamics: The introduction of new pets or family members, or significant changes in household routines, can trigger resource guarding in previously non-guarding dogs.
  • Medical Issues: Underlying health conditions can influence behavior changes, including resource guarding, especially if a dog experiences pain or discomfort.
  • Lack of Training or Socialization: Inadequately trained or socialized dogs may not learn to comfortably share or feel secure with others near their possessions.

How to Manage Resource Guarding in Dogs?

Fortunately, resource guarding can be effectively managed with the right approach and guidance. Here are some tips to help you address and stop this behavior in your dog:

1. Establishing a Safe Feeding Environment

To manage dog food guarding, create a stress-free feeding space. This involves allowing the dog to eat in a separate area without feeling threatened. Post-meal practices such as adding treats can reinforce positive associations with human presence.

2. Building Confidence and Security

Reinforcing positive behavior and providing a structured routine can significantly reduce resource-guarding tendencies. Training commands like "drop it" or "leave it" are essential in teaching dogs to willingly give up guarded items.

3. Training Against Guarding

Proactive training strategies focus on modifying a dog's response to perceived threats. Gradually introducing scenarios where a dog learns that human intervention means additional rewards, not loss, can help in altering their guarding behavior.

4. Resource Guarding Between Dogs

In multi-dog households, it's important to manage interactions during feeding or playtime to prevent resource guarding between dogs. Strategies include feeding dogs separately and controlling access to high-value toys or treats.

5. Environmental Management

Modify the dog's environment to reduce the opportunities for guarding. This might include removing high-value items when guests are present or when the dog cannot be supervised.

6. Avoid Punishment

Punishing a dog for guarding can exacerbate the problem by increasing their anxiety and fear. Always opt for positive training methods. Use positive reinforcement when at all possible.

How Can You Prevent Resource Guarding in First Place?

Preventing resource guarding in dogs starts early and focuses on fostering positive associations and behaviors around resources. Key to this prevention is ensuring good health and nutrition for puppies, which sets a foundation for well-balanced behavior. It’s important to minimize social competition, especially in multi-dog households, by avoiding or managing group feedings and high-valued resource contexts. This approach helps lessen a dog's fear of losing resources and curbs the development of guarding behaviors.

Inappropriate training techniques and positive punishment should be avoided. Actions like taking away toys, bones, or food, or retrieving items the dog has taken, can inadvertently encourage resource guarding. Instead, engage puppies in positive interactive play, such as tug games, where they are allowed to win and keep the object. This helps build a healthy human-dog dynamic. It’s also beneficial to avoid adding drama when a dog picks up or steals an item and to refrain from punishing them with these items.

Ignoring attention-seeking behaviors can prevent them from being reinforced. Additionally, adding tasty treats to the food bowl while the dog eats, without removing the resource, can result in positive feelings about human presence.

How to Live with a Dog that Resource Guards?

Living with a dog that exhibits resource-guarding behaviors requires patience, understanding, and a consistent approach to management. For dog owners, it's important to recognize and respect the dog's space, especially around their food, toys, or other valued items. This doesn't mean allowing the dog to display aggressive behaviors, but rather understanding their need for security and working to gradually build trust.

In households with multiple dogs, it's essential to monitor interactions closely, particularly around resources like food bowls, toys, and resting places. Ensuring each dog has their own space and resources can help minimize conflict and stress. If one dog shows signs of resource guarding, consider feeding them separately or providing toys only during individual playtime to prevent any potential disputes.

Introducing a new dog or family member to a home with a resource-guarding dog should be done gradually and with careful supervision. Initial interactions should be in neutral environments and without the presence of guarded items. Over time, as the dogs become more comfortable with each other, supervised and controlled access to resources can be attempted, always being mindful of the guarding dog's body language and comfort level.

Training and behavior modification plays an important role in living with a resource-guarding dog. Engaging in regular training sessions, using positive reinforcement, and working on commands that encourage relinquishing resources willingly can significantly improve the situation. In more challenging cases, seeking the help of a professional dog trainer or veterinary behaviorist is advisable. They can offer tailored strategies and support for managing and modifying the guarding behavior.

Above all, dog owners need to remain calm and patient. Punishment or forceful attempts to remove guarded items can worsen the behavior and damage the trust between the dog and its owner. Understanding, empathy, and a consistent, positive approach are key to successfully living with and managing a dog that resource guards.


In conclusion, managing and preventing resource guarding in dogs is an achievable goal. It involves an empathetic understanding of the dog's perspective, proactive training strategies, and above all, patience. The key lies in creating a safe space, minimizing social competition, and consistently reinforcing desired behaviors. Living with a dog that resource guards requires strategic environmental management and can greatly benefit from professional guidance in challenging cases. Never resort to punishment, as it can exacerbate the problem. Instead, foster positive associations, respect the dog's space, and steadily build trust. Ultimately, a compassionate and knowledgeable approach can transform potential conflicts into opportunities for bonding and behavioral growth.
