What Is Separation Anxiety in Dogs?

Separation anxiety is a behavioral condition in which a dog experiences intense distress when left alone or separated from their guardian. While many dogs may bark occasionally or seem unhappy when their people leave, dogs with true separation anxiety display more severe and often destructive behaviors that go beyond simple boredom or a need for training.

Common signs of separation anxiety may include:

• Excessive barking or howling shortly after being left alone
• Destructive behavior such as chewing, digging, or scratching—especially around doors and windows
• Urinating or defecating indoors, despite being house trained
• Pacing, drooling, or other physical signs of anxiety
• Attempts to escape, which can result in injury

It’s important to understand that not every dog who shows one or more of these behaviors necessarily has separation anxiety. Many of these signs can also stem from other causes, such as a lack of mental stimulation, poor house manners, or even a change in routine. It's perfectly normal—and emotionally healthy—for a dog to miss their human when they’re gone.

Dogs are social animals, and their bond with their people is often very strong. Also, dogs do not perceive time the same way humans do. So, when dogs act overjoyed to see their guardian after a short absence, it doesn’t necessarily mean they were suffering in distress—it could simply reflect their excitement at the reunion.

Separation anxiety isn’t a sign of disobedience or bad behavior—it’s a true emotional response rooted in fear and attachment. Understanding what is and what isn’t separation anxiety is the first step in helping your dog feel more secure and happy while you're away.

What Causes Separation Anxiety in Dogs?

There’s no single cause of separation anxiety in dogs, and researchers haven’t yet identified exactly why some dogs develop it while others do not. However, patterns have emerged that suggest certain experiences and environmental factors may increase a dog’s risk. One of the strongest indicators is a history of change or loss.

Dogs who have been surrendered to shelters, rehomed, or passed between multiple guardians are significantly more likely to develop separation anxiety than dogs who have remained with one person or family since puppyhood. The loss of a previous caregiver—or even a more subtle change in the household, like a family member moving out—can leave a dog feeling insecure and anxious about being left alone again.

Some life changes that may contribute to separation anxiety include:

• Being surrendered to an animal shelter or rescue
• Changes in the household routine, such as a new work schedule
• Moving to a new home
• Loss of another pet in the household
• Change in the family structure (e.g., divorce, child going to college)

While these events can increase the likelihood of separation anxiety, it’s important to understand that how a dog is raised and supported also plays a role. Good socialization starting early in life—ideally beginning with a responsible breeder or rescue and continuing in the new home—can help prevent fear-based behaviors. Teaching a puppy or newly adopted dog how to feel safe when left alone is a valuable life skill.

Steps to help reduce the likelihood that a dog will develop separation anxiety:

• Crate training

• confidence-building exercises

• gradual desensitization to being alone

• structured routines

These proactive steps can also help dogs with mild anxiety from worsening, especially during life transitions. Ultimately, every dog is an individual. Some may be more genetically predisposed to anxiety, while others may react to environmental stressors more intensely. The good news is that with the right support, most dogs can learn to feel safer and more secure when left alone.

How to Treat and Manage Separation Anxiety in Dogs

Helping a dog with separation anxiety takes time, consistency, and patience. The good news is that most dogs can improve with the right approach. Treatment strategies depend on the severity of the anxiety and the individual dog’s needs. Below are methods for managing and reducing separation anxiety, from mild to more complex cases.

Mild Separation Anxiety signs:

• Pacing
• Whining
• Following their guardian closely before departure

Prevention and confidence-building strategies:

• Desensitize departures: Pick up your keys, put on your shoes, or grab your bag—then don’t leave. Repeat often. This helps your dog stop associating these cues with being left alone.
• Short, low-key departures and returns: Avoid dramatic goodbyes or overly enthusiastic reunions. Keeping comings and goings calm can reduce emotional spikes.
• Offer enrichment during alone time: Use puzzle toys, KONGs stuffed with high-value treats, or slow feeders to keep your dog busy and help them associate alone time with good things.
• Exercise first: A tired dog is less likely to become anxious. A walk or play session before you leave can set the stage for rest.

Moderate Separation Anxiety signs:

• Barking
• Destructive chewing near exit points
• House soiling shortly after their guardian leaves

Prevention and confidence-building strategies:

• Gradual desensitization to alone time: Start by leaving your dog alone for just a few minutes and gradually increase the duration. This requires many short, successful sessions over time.
• Create a “safe zone”: Some dogs do best with a designated calm area—like a crate (if properly crate-trained), a playpen, or a quiet room with familiar items.
• Counter-conditioning: Help your dog form new emotional associations to being alone. For example, always give a special high-reward treat or chew only when you leave—and take it away once you return.
• Consistency in routine: Dogs thrive on predictability. A structured daily routine can help lower overall stress and reduce anxiety around departures.

Severe Separation Anxiety signs:

• Panic as soon as they realize their guardian is leaving
• Destructive behavior such as destroying doors or windows
• trying to escape,
• nonstop barking and/or excessive drooling

Prevention and confidence-building strategies:

• Work with a professional: A certified dog trainer or veterinary behaviorist can tailor a desensitization program specific to your dog’s needs. Severe cases require slow, methodical progress with expert guidance.
• Avoid long absences when your puppy/dog is first introduced into your home
• Arrange for pet sitters, doggy daycare, or a trusted friend or family member to help care for your dog while you work on treatment.
• Consider medication: For some dogs, short- or long-term anxiety medications (prescribed by a vet)
