Why Do Puppies Hate Crates

Crates can be an essential tool for dog owners, providing a safe and comfortable space for their furry friends. However, many puppies display anxiety or fear when placed in a crate, leading to a negative association with this valuable training aid.

By exploring the underlying factors that contribute to this aversion, we can gain a better understanding of how to effectively introduce and use crates in a way that promotes a positive and stress-free experience for our puppies.

Understanding the Natural Instincts and Behavior of Puppies

Puppies, just like their wild ancestors, have a natural denning instinct. In the wild, dogs would seek out small, enclosed spaces to create their dens, which provided them with a sense of security and protection. This denning instinct is deeply ingrained in their DNA and can significantly influence their perception of crates.

Denning Instinct

The denning instinct is a powerful driving force behind a puppy’s aversion to crates. 

Dogs have an innate need for a safe and secure den-like space where they can retreat, relax, and sleep.In the wild, this den would provide protection from predators and harsh weather conditions. 

When placed in a crate, puppies may initially view it as a confined space that restricts their freedom rather than a safe den-like environment.

Example: Imagine a puppy in the wild. It would seek out a small, hidden space such as a cave or a hollow tree to curl up in. This instinct is still present in domesticated dogs today. When placed in a crate, puppies may perceive it as an unnatural confinement rather than a comfortable den. Their aversion to the crate stems from this perception of restriction.

Pack Mentality

Dogs are pack animals with a strong need for social interaction and companionship. In the wild, dogs would live and hunt together in packs, relying on each other for survival. 

When puppies are separated from their littermates and placed in a crate alone, they may experience fear and anxiety due to the instinctual need to be part of a pack. The sense of isolation can trigger stress and discomfort, further reinforcing their aversion to the crate.

Example: Puppies are accustomed to the constant presence and socialization with their littermates and mother. Being suddenly placed in a crate away from the familiar sounds and smells of their pack can be distressing for them. They may exhibit signs of separation anxiety or distress when left alone in a crate due to the instinctual need for companionship and social connection.

Understanding these natural instincts and behaviors is crucial in addressing crate aversion. By acknowledging the denning instinct and the importance of social interaction, we can implement strategies that make the crate feel like a secure and comforting space for our puppies.

It’s important to note that while these natural instincts play a significant role in crate aversion, they can be mitigated with proper training, positive reinforcement, and gradual exposure to the crate.

By creating positive associations and addressing any underlying fears or anxieties, we can help puppies overcome their aversion and develop a positive relationship with their crates.

Early Experiences and Trauma

The early experiences a puppy has can greatly impact their behavior and attitude towards crates. Negative experiences or traumatic events associated with crates can create long-lasting associations, leading to crate aversion.

Role of Early Experiences

Puppies are highly impressionable during their early developmental stages, which typically occur between 3 and 14 weeks of age. 

Positive experiences during this critical period can shape their behavior and help them form positive associations. Conversely, negative experiences can have long-lasting effects, including fear and aversion towards specific stimuli, such as crates.

Example: If a puppy had a negative experience, such as being left alone for long periods in a crate without proper introduction or positive reinforcement, they may associate the crate with feelings of fear, isolation, or abandonment. This negative experience can create a lasting aversion to crates.

Potential Negative Experiences

There are several situations that can contribute to a negative association with crates. These may include:

  • Being confined in a crate for excessive periods without breaks or social interaction.
  • Feeling trapped or uncomfortable due to an improperly sized crate.
  • Experiencing loud noises or sudden movements while in the crate, causing fear or anxiety.
  • Being forced into a crate without proper introduction or positive reinforcement.

Example: Suppose a puppy was placed in a crate that was too small, causing discomfort and restricted movement. Additionally, if the puppy was not given regular breaks or social interaction while in the crate, they may develop negative feelings towards it. These negative experiences can contribute to crate aversion.

Traumatic Events

Puppies who have experienced traumatic events while in a crate may develop a strong aversion towards it. 

Traumatic events could include accidents, injuries, or intense fear-inducing situations that occurred while confined in a crate. These events can create lasting associations with fear, stress, or anxiety when placed in similar situations.

Example: If a puppy experienced a loud thunderstorm while confined in a crate and felt terrified and unable to escape, they may develop a fear of crates as a result. The traumatic event of the thunderstorm combined with the confinement of the crate can create a strong aversion to crates.

Understanding the role of early experiences and trauma in crate aversion is crucial for addressing and overcoming this issue.

By providing positive experiences, gradual introduction, and using appropriate training techniques, we can help puppies overcome negative associations and develop a positive relationship with crates.

Lack of Familiarity and Exposure to Crates

One common reason why puppies develop an aversion to crates is their lack of familiarity and exposure to this particular training tool. 

A crate can be a foreign and unfamiliar environment for a puppy, which can lead to fear, anxiety, and resistance when introduced to one.

Gradual Introduction

Introducing a crate gradually is essential for helping puppies become familiar with it and develop positive associations. Rushing the process or forcing a puppy into a crate can worsen their aversion. Instead, it’s important to take small steps and allow them to acclimate at their own pace.

Example: Start by leaving the crate open and accessible in a safe and comfortable area of the house. Place treats, toys, and bedding inside to make it inviting.

Encourage the puppy to explore the crate voluntarily without any pressure or confinement. Gradually increase the time spent inside the crate while providing positive reinforcement, such as treats and praise.

Positive Exposure

Creating positive associations with the crate is crucial for overcoming aversion. By associating the crate with pleasant experiences, puppies are more likely to view it as a safe and comfortable space rather than a source of fear or confinement.

Example: Make the crate a positive and rewarding place for your puppy. Use treats, toys, or a special blanket that they love and associate them with the crate.

Feed them their meals inside the crate to create positive associations with mealtime. Additionally, consider providing interactive toys or chew treats to keep them occupied and engaged while in the crate.

Counteracting Fear and Anxiety

If a puppy already exhibits fear or anxiety towards a crate due to lack of familiarity, it’s crucial to address these emotions before proceeding with crate training. Trying to force a fearful puppy into a crate can worsen their aversion and lead to even stronger negative associations.

Example: Focus on desensitization exercises to gradually reduce fear and anxiety. Start by feeding the puppy near the crate, gradually moving the food bowl closer over time.

Once they are comfortable eating near the crate, place the food bowl just inside the doorway, and eventually move it further inside. This gradual approach helps the puppy associate positive experiences with being near and inside the crate.

By gradually introducing puppies to crates and creating positive associations, we can help alleviate their aversion.

Size and Comfort of the Crate

The size and comfort of the crate play a significant role in a puppy’s perception and acceptance of it. If the crate is too small or uncomfortable, it can exacerbate their aversion and make crate training more challenging. Ensuring the crate is appropriately sized and comfortable is essential for creating a positive association.

Choosing the Right Size Crate

Selecting the right size crate is crucial to ensure the comfort of your puppy. A crate that is too small will restrict their movement and make them feel cramped, while a crate that is too large may not provide the cozy and secure feeling they instinctively seek.

Example: Measure your puppy’s height from the floor to the top of their shoulders and their length from the tip of their nose to the base of their tail. Add a few inches to both measurements to determine the appropriate crate size.

The crate should be large enough for them to stand, turn around, and lie down comfortably without excess space.

Comfortable Interior

Creating a comfortable interior within the crate can help puppies develop a positive association with it. Providing soft bedding, such as blankets or a cozy dog bed, adds comfort and warmth to the crate. It mimics the feeling of a den and can make the puppy feel more secure and relaxed.

Example: Ensure that the bedding material is suitable for your puppy’s needs. Avoid materials that can be easily chewed or ingested. Opt for washable bedding that is soft and cozy, promoting a comfortable environment.

Proper Ventilation and Temperature

Maintaining proper ventilation and temperature within the crate is essential for the puppy’s comfort. A crate that becomes too hot or lacks sufficient airflow can cause discomfort and increase anxiety levels.

Example: Ensure that the crate is placed in a well-ventilated area of your home, away from direct sunlight or drafts. Monitor the temperature to ensure it remains within a comfortable range for your puppy. Consider using a crate fan or providing appropriate bedding to help regulate temperature.

By selecting an appropriately sized crate, creating a comfortable interior, and maintaining proper ventilation and temperature, we can help alleviate any physical discomfort or aversion related to the crate. This promotes a positive and inviting environment for puppies, making them more receptive to crate training.

Lack of Positive Reinforcement and Training Techniques

The lack of positive reinforcement and improper training techniques can contribute to a puppy’s aversion to crates. It’s important to use effective training methods that focus on positive reinforcement to create a positive association with the crate.

Significance of Positive Reinforcement

Positive reinforcement is a powerful training technique that involves rewarding desired behaviors with praise, treats, or other rewards. When it comes to crate training, positive reinforcement helps puppies associate the crate with positive experiences and encourages them to willingly enter and stay in the crate.

Example: Whenever your puppy voluntarily enters the crate or exhibits calm behavior inside, reward them with treats, praise, or a special toy. This positive reinforcement reinforces the idea that being in the crate is a positive and rewarding experience.

Improper Training Techniques

Using punishment or forceful methods during crate training can lead to fear, anxiety, and resistance towards the crate. It’s important to avoid techniques that cause distress or discomfort to the puppy, as this can worsen their aversion.

Example: Avoid physically forcing a puppy into the crate or using harsh verbal commands. Instead, focus on positive reinforcement and gradual desensitization techniques. Punitive measures can create negative associations with the crate and hinder the training process.

Effective Positive Reinforcement Methods

Implementing effective positive reinforcement methods can help puppies overcome their aversion to crates and develop a positive association with them. Some techniques include:

  • Using treats or toys to lure the puppy into the crate, rewarding them for entering voluntarily.
  • Gradually increasing the duration of time spent in the crate while providing positive reinforcement for calm behavior.
  • Pairing crate time with enjoyable activities, such as puzzle toys or chew treats.
  • Using verbal cues or commands associated with crate training, such as “crate” or “kennel,” and rewarding the puppy for responding to these cues.

Example: Begin by introducing the puppy to the crate using treats or toys as rewards for entering. Gradually increase the duration of time they spend in the crate while providing positive reinforcement for calm behavior. As they become more comfortable, introduce verbal cues like “crate” and reward them for responding to the command.

By focusing on positive reinforcement techniques, we can create a positive association with crates and make the training experience enjoyable for puppies. This approach encourages cooperation and reduces aversion, leading to successful crate training outcomes.

Separation Anxiety and Fear of Isolation

Separation anxiety and the fear of isolation are common reasons why puppies start whining when they are in the crate at night.

Understanding and addressing these emotions is crucial for successful crate training and helping puppies feel comfortable and secure in their crates.

Separation Anxiety

Separation anxiety is a condition in which puppies experience extreme distress when separated from their owners or the pack. Being confined in a crate can amplify feelings of anxiety and fear, making the crate a trigger for their anxiety rather than a safe space.

Example: A puppy with separation anxiety may exhibit behaviors such as excessive whining, barking, destructive chewing, or attempts to escape the crate. These behaviors stem from their fear and discomfort with being separated from their loved ones.

Fear of Isolation

Dogs are social animals that thrive on companionship and interaction. The fear of isolation can contribute to a puppy’s aversion to crates. They may associate being confined in a crate with being alone and cut off from their pack, triggering feelings of fear and distress.

Example: A puppy with a fear of isolation may show signs of anxiety, restlessness, or attempts to escape when placed in a crate alone. They may vocalize or exhibit behaviors associated with panic, such as excessive panting or pacing.

Addressing Separation Anxiety and Fear

Addressing separation anxiety and fear of isolation is crucial for successful crate training. It’s important to gradually introduce the concept of separation while providing comfort, reassurance, and positive reinforcement.

Example: Start by placing the puppy in the crate for short periods while you remain nearby. Gradually increase the duration of time spent in the crate, always providing positive reinforcement for calm behavior.

Incorporate desensitization techniques by simulating departures and returns without making them too dramatic or stressful. This helps the puppy understand that being in the crate does not always lead to extended periods of isolation.

Additional Strategies

In addition to gradual desensitization, other strategies can help address separation anxiety and fear of isolation:

  • Provide stimulating toys or treats to keep them occupied while in the crate.
  • Utilize calming aids such as pheromone sprays or diffusers.
  • Establish a consistent routine for crate training and daily activities to create a sense of security.
  • Consider professional help from a dog trainer or behaviorist experienced in addressing separation anxiety if the issue persists.

By addressing separation anxiety and fear of isolation through gradual desensitization, positive reinforcement, and additional strategies, we can help puppies develop a positive association with crates and alleviate their aversion.

Crate training can become an effective tool for managing separation anxiety while providing a safe and secure space for puppies.

Gradual Desensitization and Counterconditioning Techniques

Gradual desensitization and counterconditioning are effective techniques for helping puppies overcome their aversion to crates and develop positive associations with them. These techniques involve gradually exposing the puppy to the crate in a controlled and positive manner.

Gradual Desensitization

Gradual desensitization involves slowly exposing the puppy to the crate, starting with minimal stress or discomfort, and gradually increasing the intensity of the exposure over time. This technique helps the puppy become accustomed to the crate without triggering fear or anxiety.

Example: Begin by leaving the crate open and accessible in a familiar room. Encourage the puppy to approach and explore the crate at their own pace without any pressure.

As they become more comfortable, gradually increase their exposure by placing treats or toys near the crate, then inside the doorway, and eventually further inside. Progress at a pace that allows the puppy to remain relaxed and confident.


Counterconditioning involves changing the puppy’s emotional response to the crate from negative or fearful to positive and relaxed. This technique pairs the presence of the crate with enjoyable experiences or rewards, creating positive associations.

Example: Whenever the puppy willingly enters or stays in the crate, provide treats, praise, or a special toy as a reward. Associate positive experiences such as mealtime or playtime with being in the crate.

Over time, the puppy will start to associate the crate with positive things and develop a more favorable attitude towards it.

Step-by-Step Guidance

Implementing gradual desensitization and counterconditioning techniques requires a structured approach. Breaking down the process into manageable steps helps ensure success and prevents overwhelming the puppy.


  1. Start by introducing the crate in a non-threatening manner, such as leaving it open with enticing treats inside.
  2. Gradually encourage the puppy to approach and explore the crate voluntarily.
  3. Once comfortable entering the crate, begin closing the door for short durations while providing rewards.
  4. Increase the duration of time spent in the crate gradually, always rewarding calm behavior.
  5. Practice leaving and returning to the room while gradually increasing the duration of absences.
  6. Continue reinforcing positive associations with the crate through treats, toys, and praise.

By following a step-by-step guidance plan, owners can ensure a systematic and positive approach to crate training. This helps puppies gradually overcome their aversion and develop a positive relationship with their crates.

It’s important to note that each puppy is unique, and progress may vary. Patience, consistency, and adapting to the puppy’s needs are key in successfully implementing gradual desensitization and counterconditioning techniques.

Benefits of Crate Training for Puppies

Crate training offers numerous benefits for puppies beyond just providing a safe and secure space. Understanding these benefits can help dog owners appreciate the value of crate training and motivate them to overcome their puppy’s aversion.


Crate training is an effective tool for housebreaking puppies. Dogs naturally avoid soiling their sleeping area, making the crate an excellent aid in teaching them bladder and bowel control.

Example: When used properly, a crate can help establish a routine for bathroom breaks and reinforce the concept of pottying outside. By confining the puppy in the crate when they cannot be supervised, owners can prevent accidents and encourage them to hold their bladder or bowel movements until they are taken outside.

Safety and Security

A properly sized and comfortable crate provides a safe and secure space for puppies. It serves as their den-like habitat, offering a retreat where they can feel protected and at ease.

Example: A crate can keep puppies out of harm’s way by preventing them from accessing hazardous objects or areas when unsupervised. It also provides a secure space during times when external stimuli may cause anxiety, such as during thunderstorms or fireworks.


Crate training makes traveling with puppies much safer and more convenient. Whether it’s a short car ride or a longer journey, crates provide a familiar and secure space for puppies to travel in.

Example: Using a crate in the car prevents puppies from wandering around or becoming a distraction to the driver. It also reduces the risk of injury in case of sudden stops or accidents. Additionally, when staying in hotels or visiting friends and family, having a crate-trained puppy ensures they have a comfortable and familiar space to relax in.

Management of Destructive Behavior

Puppies can be prone to destructive behavior, especially when left unattended. Crate training helps manage and prevent destructive behaviors by confining puppies to a safe area.

Example: When puppies are left alone, their natural curiosity can lead them to chew on furniture, shoes, or other household items. By using a crate during these times, owners can prevent destructive behavior and protect their belongings while providing the puppy with an appropriate space to relax and settle down.

Facilitating Training and Boundaries

Crate training aids in establishing boundaries and facilitating other forms of training. It teaches puppies impulse control and helps them understand acceptable behavior within the home.

Example: Using the crate as part of a structured training routine helps puppies learn to wait patiently, settle down, and follow commands. It also helps establish a sense of routine and discipline, which can be beneficial in various areas of training, such as basic obedience and manners.
