Separation Anxiety in Dogs and Cats: Signs, Causes & What Helps

You close the front door, drive away, and five minutes later your camera shows your dog pacing from window to window.

Or maybe your cat seems perfectly independent—until you start finding urine on the bed after long days away.

Those behaviors can be related to separation.

They can also have completely different causes.

A chewed door, hours of barking, or a litter-box accident tells you what happened. It does not automatically tell you why.

That is why the first step is not training harder.

It is finding out what your pet actually experiences after you leave.

Quick Answer: Separation anxiety is a recognized fear- and anxiety-related disorder in dogs. Cats can also show separation-related behaviors, but feline research suggests those behaviors may reflect several different motivations rather than one uniform syndrome. Video, medical evaluation, careful attention to timing and triggers, and gradual training below the animal's distress threshold are more useful than diagnosing the problem from damage, barking, or accidents alone.

What Is Separation Anxiety in Dogs?

Veterinary behavior literature increasingly uses the term separation distress disorder for fear or anxiety that develops during—or sometimes in anticipation of—the absence of an important person or human company.

Not every affected dog has the same pattern.

Some dogs become distressed when one particular person leaves even if another familiar person remains.

Others are comfortable as long as someone is present but panic when completely alone.

That distinction matters because the trigger and management plan may differ.

What Does Separation Distress Look Like?

Possible signs include:

• Barking, whining, or howling
• Pacing or inability to settle
• Panting or excessive salivation
• Scratching or chewing doors and windows
• Escape attempts
• Urination or defecation indoors
• Refusing food while alone
• Repetitive behavior
• Trembling or hypervigilance
• Distress during departure preparations

Many dogs show obvious changes relatively early in an absence, commonly within the first 15–30 minutes.

Some begin reacting even earlier when the owner puts on work shoes, picks up keys, or approaches the door.

But there is no diagnostic stopwatch.

A dog does not need to bark by minute 10 or destroy something by minute 20 to qualify.

The Best First Step: Record What Happens After You Leave

A pet camera, security camera, or spare phone can give you information that the condition of the house cannot.

Record several ordinary departures and look for:

• When the first signs begin
• Whether your pet eventually settles
• Where they spend their time
• Whether they eat
• Whether they repeatedly check doors or windows
• Whether a sound outside triggers the behavior
• Whether confinement appears to make things worse
• Whether the behavior occurs specifically during absence

The evidence begins after the door closes. Your neighbor may report that your dog “barks whenever you're gone,” but video might show 25 quiet minutes followed by barking when a delivery truck arrives. That points toward a very different problem from immediate separation panic.

Video also becomes useful later because it shows whether training absences are actually staying below your dog's anxiety threshold.

Separation Anxiety, Boredom, or Something Else?

Clue	Separation Distress May Be More Likely	Another Cause May Be More Likely
Timing	Signs begin around departure or relatively soon afterward	Behavior begins later, inconsistently, or after another trigger
Body language	Pacing, panting, salivation, scanning, trembling, inability to settle	Exploratory activity without obvious fear or panic
Destruction	May concentrate around exits, barriers, or escape routes	Items throughout the home are investigated opportunistically
Food	A highly anxious dog may ignore favorite food	A bored dog may readily engage with enrichment and later settle
Relationship to absence	Strongly linked to the person leaving or the dog being alone	Similar behavior also occurs while people are present

Other possibilities include incomplete housetraining, noise sensitivity, barrier frustration, confinement anxiety, scavenging, insufficient activity, pain, cognitive changes, and medical disease.

Our dog and cat body-language guide can help you interpret posture and stress signals without relying on one behavior alone.

Following You Everywhere Does Not Prove Separation Anxiety

A dog following you from room to room can simply be social behavior, learned routine, curiosity, or a history of being rewarded for staying close.

Merck notes that close-attachment behaviors such as following family members around the home do not by themselves identify dogs at greater risk of separation distress.

If your dog is a classic shadow companion but remains relaxed when left alone, see our guide to why dogs follow their owners everywhere before treating closeness itself as a disorder.

Can Cats Have Separation Anxiety?

Cats form meaningful relationships with people and can show behavior associated with social separation.

But the feline evidence base is much smaller than the canine one, and the diagnosis appears less straightforward.

A 2020 survey involved 223 cats. Thirty cats met at least one of the researchers' behavioral criteria for possible separation-related problems.

Reported behaviors included:

• Destructive behavior
• Excessive vocalization
• Urination or defecation outside the litter box
• Reduced activity or apathy
• Aggressive behavior
• Agitation or anxiety

But a 2023 study of 133 cats found that 12 separation-related behaviors did not cluster into one simple syndrome.

Instead, researchers identified four dimensions involving:

• Responses to departure cues
• Protest when the human was inaccessible
• Unusual elimination
• Negative responses following separation

The authors suggested that different motivational states may underlie behaviors that owners interpret as separation problems.

For cats, use the label carefully. “Separation-related behavior” is often more accurate than assuming every cat has the same disorder—or needs the same treatment protocol—as a dog with diagnosed separation anxiety.

Don't Diagnose a Cat From a Litter-Box Accident

Urination outside the litter box has many possible causes.

They include:

• Lower urinary tract disease
• Pain
• Litter-box aversion
• Urine marking
• Conflict with another cat
• Environmental stress
• Mobility problems
• Other medical disease

If house-soiling begins suddenly, medical evaluation and a review of the litter-box environment should come before assuming the cat is angry or anxious because you went to work.

Urinary emergency: If a cat repeatedly strains to urinate and produces little or no urine—especially a male cat—seek urgent veterinary care. That pattern can indicate urethral obstruction and should not be treated as a behavioral separation problem.

How Is Canine Separation Anxiety Treated?

The goal is not simply to stop barking or save the door frame.

The goal is to reduce the fear driving the behavior.

1. Begin Below the Dog's Anxiety Threshold

For moderate or severe separation distress, graduated departure training is a central behavioral approach.

Start with an absence short enough that the dog remains comfortable.

For one dog, that might initially be several minutes.

For another, it may be only a few seconds.

Return before clear distress develops, and increase duration gradually as the dog succeeds.

Don't use “cry it out” for separation panic. Leaving a frightened dog alone until they eventually stop reacting is not graduated desensitization. Repeated full-intensity distress can strengthen fear and may increase the risk of escape-related injury.

2. Use Video to Measure the Threshold

Early signs that a practice absence is becoming too difficult may include:

• Stopping a chew or food toy
• Standing and staring toward the exit
• Repeatedly checking the door
• Pacing
• Panting
• Whining
• Becoming unable to settle

If those changes appear, the next practice absence usually needs to be shorter or easier.

3. Food Toys Help Only When the Dog Can Actually Eat

For mild cases, a high-value food toy may help build a positive association with comfortable alone time.

But severe anxiety often suppresses appetite.

If your dog normally loves a particular food but abandons it immediately after you leave, the lesson is not necessarily “buy a better treat.”

The absence may already be too difficult.

4. Build Comfortable Independence Without Withholding Affection

It can be useful to reinforce relaxed activities that do not require constant physical contact with you.

Examples include resting on a bed, using a food puzzle, chewing an appropriate item, or relaxing behind a gate while you remain nearby.

This is not about making the dog less attached to you.

Affection does not cause separation anxiety.

The goal is simply to add more experiences in which calm independence is safe and rewarding.

5. Meet Normal Behavioral Needs

Appropriate exercise, sniffing, play, training, enrichment, social opportunities, and rest support behavioral health.

They do not cure a fear disorder by themselves.

Trying to exhaust an anxious dog until they are too tired to panic is not separation-anxiety treatment.

What About Keys, Shoes, and Other Departure Cues?

Some dogs react to the routine that predicts departure before the owner actually leaves.

Keys, shoes, work clothes, bags, or a particular sequence of actions can become learned predictors.

Practicing some cues without leaving may help individual dogs, but current treatment guidance places greater emphasis on the actual separation remaining below threshold.

Do not spend weeks picking up your keys randomly while every real departure still produces panic.

Should You Ignore Your Dog Before Leaving?

No evidence requires becoming emotionally cold before work.

If elaborate goodbyes clearly increase arousal, making departures calmer and more predictable is reasonable.

But you do not need to ignore your dog for a fixed 10, 20, or 30 minutes before leaving or after returning.

A calm goodbye and reunion are appropriate for many dogs.

Should You Crate a Dog With Separation Anxiety?

Only when that individual dog already feels safe and relaxed in the crate.

For some dogs, a crate is a familiar resting place.

For others, separation distress overlaps with confinement anxiety.

A panicking dog may bite bars, damage teeth, injure paws or nails, or force through a door trying to escape.

If video shows that confinement makes distress worse, using a crate simply to protect the house can turn a behavior problem into an injury risk.

For a puppy learning to enjoy a crate before severe separation problems develop, our calm puppy crate-training guide covers that separate skill.

Prevent Repeated Full-Panic Absences When You Can

This is one of the hardest parts of real treatment.

Your dog may currently tolerate only two minutes while your workday requires several hours.

When practical, temporary management can include:

• A trusted family member
• A pet sitter
• A familiar friend or neighbor
• Daycare when the individual dog genuinely enjoys it
• Taking the dog with you when safe and realistic

The purpose is not permanent dependence on a sitter.

It is to reduce repeated episodes of overwhelming fear while training gradually increases comfortable alone time.

Can Medication Help?

Yes.

Medication can be particularly useful when anxiety is intense enough to interfere with learning or when real-life absences cannot always stay within the dog's current training threshold.

Medication is not simply about sedating the dog.

The aim is to reduce pathological anxiety enough that management and behavior modification can work more effectively.

Current FDA-Approved Canine Options in the United States

Veterinary formulations of fluoxetine and clomipramine are FDA-approved for canine separation anxiety as part of a broader behavior-management plan.

There is also a newer situational option.

On May 6, 2026, the U.S. FDA approved Tessie (tasipimidine oral solution) for the treatment of both separation anxiety and noise aversion in dogs.

The FDA describes Tessie as typically being administered about one hour before the dog is expected to be left alone, according to the prescribing veterinarian and product label.

The right medication strategy depends on the individual dog, medical history, other medications, pattern of anxiety, unavoidable absences, and behavior plan.

Do not start, combine, adjust, or stop behavioral medication without veterinary guidance. These medications differ in onset, duration, contraindications, interactions, and monitoring requirements.

Do Calming Supplements, Pheromones, or Music Work?

Supplements, pheromone products, pressure garments, background audio, and other calming tools may help individual animals.

The quality of evidence varies widely between products.

Think of them as possible additions—not replacements for diagnosis, management, and structured behavior modification when an animal is experiencing genuine panic.

Be cautious with anything advertised as a guaranteed separation-anxiety cure.

How Should Separation-Related Behavior in Cats Be Managed?

Because feline research is more limited, begin with three questions:

1. Could a medical problem explain the behavior?
2. Are the cat's environmental and social needs being met?
3. Does the behavior actually track a particular person's absence?

Current feline environmental guidance emphasizes:

• Safe resting and hiding places
• Multiple, separated key resources
• Elevated locations
• Scratching opportunities
• Interactive play and hunting-style activities
• Food puzzles when the cat enjoys them
• Predictable, positive human interaction
• Choice and control over social contact

If video suggests that a cat is specifically distressed by separation from one person, comfortably brief periods of independence may be useful as part of an individualized plan.

But do not copy a canine graduated-departure protocol onto every cat without considering medical health, territory, resource placement, social relationships, and the particular behavior involved.

For broader home setup and environmental needs, see our first-time cat owner guide.

Never Punish Separation-Related Behavior

A dog does not interpret punishment at 6 p.m. as treatment for a door frame chewed hours earlier.

And punishment does not remove the fear that produced the behavior.

The same applies to cats.

Do not punish:

• Urine or feces found after an absence
• Chewed objects
• Scratching
• Vocalization recorded while you were away

Anxiety-related behavior is not revenge or spite.

Focus on identifying what happened and preventing the next overwhelming episode.

Noise Fear Can Masquerade as Separation Anxiety

Some dogs remain comfortable alone until something frightening happens outside.

Thunder, construction, alarms, traffic, deliveries, or other sudden noises can trigger pacing, barking, destruction, or escape attempts.

When you arrive home, the damage may look like separation anxiety.

Video can reveal that the dog actually rested normally until a specific environmental event occurred.

For more on sound-triggered fear, see our guide to noise fear in dogs and cats.

How Long Does Treatment Take?

There is no reliable universal timeline.

Progress depends on:

• How quickly anxiety begins
• How intense the distress becomes
• Whether unavoidable long absences continue
• Whether other fears or anxiety disorders are present
• Medical health
• How consistently training can be implemented
• Whether medication is appropriate

Merck notes that graduated-departure programs can take months for some dogs.

The useful measurement is not whether you have reached week four or week eight.

It is whether your dog can remain comfortable for gradually longer periods without repeatedly being pushed into panic.

When Should You Call Your Veterinarian?

Veterinary evaluation is especially important when:

• The behavior begins suddenly
• An older pet develops new anxiety or confusion
• Appetite or weight changes
• New house-soiling appears
• The animal injures themselves trying to escape
• There is severe salivation, vomiting, panting, or prolonged panic
• Your dog cannot tolerate even extremely brief absences
• Training is not progressing
• You are considering medication

Sudden behavioral changes can reflect pain, sensory decline, neurological disease, urinary or gastrointestinal problems, cognitive changes, and other medical conditions.

When Is a Veterinary Behaviorist Worth It?

Specialized help is particularly useful when distress is severe, escape attempts create an injury risk, multiple fears overlap, the diagnosis remains unclear, medication decisions are complex, or progress has stalled.

A board-certified veterinary behaviorist can assess both medical and behavioral contributors and prescribe medication when appropriate.

The American College of Veterinary Behaviorists directory can help U.S. and Canadian owners search for a specialist.

A Practical Starting Plan

1. Record several ordinary departures.
2. Note exactly when signs begin and what triggers them.
3. Rule out noise, confinement, housetraining, and medical alternatives.
4. For dogs, identify the shortest absence that remains comfortable.
5. Build duration gradually without rehearsing panic.
6. Use food enrichment only when the animal willingly engages with it.
7. Do not punish behavior found after you return.
8. Use temporary company when possible if real-life absences exceed the dog's current tolerance.
9. Discuss medication with your veterinarian when fear is severe or training cannot progress.
10. Use video to measure improvement instead of guessing.

Editorial note: Separation-related behaviors can overlap with medical disease, noise aversion, confinement anxiety, incomplete housetraining, normal exploratory behavior, environmental stress, and other behavioral conditions. Canine treatment should be individualized, and feline separation-related behavior should not automatically be treated as an identical disorder. Prescription medication requires veterinary diagnosis and supervision.

The Bottom Line

A chewed door does not tell you why it was chewed.

A barking complaint does not tell you what happened during the rest of the hour.

And a cat urinating on the bed while you are away does not automatically prove separation anxiety.

Start by watching.

Use a camera. Look at timing. Look at body language. Look for outside triggers. Rule out medical problems.

If your dog is genuinely distressed by separation, do not teach independence by repeatedly leaving long enough for panic to happen.

Build alone time from a level the dog can already handle.

For cats, take separation-related behavior seriously without forcing every case into a canine diagnosis.

The goal isn't to prove that your pet can survive being alone. It's to gradually make being apart feel safe.
