By Pat Miller

Have you ever had the misfortune of walking into your house to find overturned furniture, inches-deep claw gouges on door frames, blood-stained tooth marks on window sills, and countless messages on your answering machine from neighbors complaining about your dog barking and howling for hours on end in your absence? If so, you’re probably familiar with the term “separation anxiety” - a mild label for a devastating and destructive behavior.

Thirty years ago the phrase was uncommon in dog training circles. Today it’s a rare dog owner who hasn’t heard of separation anxiety, experienced it with a one of her own dogs, or at least had a friend

A dog with separation anxiety might not be comforted by another dog or person at home. Early on, he may be simply concerned when the human to whom he is most bonded walks out the door; later, he may panic when this happens.

whose canine companion reportedly suffered from this difficult disorder. Separation-related behaviors seem more common these days, and sadly, can also result in human frustration and anger - and sometimes even the euthanasia of an offending dog when a despairing owner reaches her wits’ end.

In her excellent book, Clinical Behavioral Medicine for Small Animals, Dr. Karen Overall defines separation anxiety as, “A condition in which animals exhibit symptoms of anxiety or excessive distress when they are left alone.” The most common signs of the condition include destructive behavior, house soiling, and excessive vocalization. Many dogs with this challenging behavior also refuse to eat or drink when left alone, don’t tolerate crating, pant and salivate excessively when distressed, and go to great lengths to try to escape from confinement, with apparent total disregard for injury to themselves or damage to their surroundings.

It’s natural for young mammals to experience anxiety when separated from their mothers and siblings; it’s an adaptive survival mechanism. A pup who gets separated from his family cries in distress, enabling Mom to easily find him and rescue him. In the wild, even an adult canine who is left alone is more likely to die - either from starvation, since he has no pack to hunt with, or from attack, since he has no pack mates for mutual protection.

Given the importance of a dog’s canine companions, it speaks volumes about the dog’s adaptability as a species that we can condition them to accept being left alone at all! We’re lucky we don’t have far more problems than we do, especially in today’s world, where few households have someone at home regularly during the day to keep the dog company.

There was a time in our society when fewer dogs were left home alone - Mom stayed home while Dad went off to work every day - so dogs had less exposure to the kind of daily isolation that contributes to separation anxiety behavior. Some behavior scientists theorize that experiencing a fear-causing event when a young dog is already mildly stressed about being alone can trigger more intense “home alone” anxiety behaviors.

In today’s world there are a significant number of dogs who are afflicted with some degree of separation distress. Fortunately, many dog owners these days are willing to seek solutions to behavior problems rather than just “getting rid of” the dog. As a result, behavior professionals are likely to see canine clients with separation distress disorders.

Differential diagnoses
Another reason separation anxiety seems more prevalent today than a few decades ago is that it is misdiagnosed with some frequency by laypersons. With an increased awareness of the condition has come an increase in misidentification of behaviors that resemble separation distress behaviors, but really aren’t.

For example, house soiling can be related to anxiety, but there are many other potential causes. These include incomplete housetraining, lack of access to appropriate elimination areas, unreasonable owner expectations (expecting the dog to “hold it” for 10 hours or more), fear, excitement, marking, submissive elimination, or physical incontinence.

Destructive behavior may be a result of separation anxiety, or it could be normal puppy behavior, play, reaction to outside stimuli, and/or an outlet for excess energy. Separation distress could be the cause of excessive barking and howling, or the dog could be stimulated to bark by street sounds (traffic, people talking), trespassers (i.e., a mail carrier, intruder, Girls Scouts selling cookies), social facilitation (other dogs barking), play, aggression, or fear.

It’s critically important that a problem behavior be correctly identified prior to the implementation of a behavior modification program. It does no good to try to modify separation anxiety if that’s not really the problem. (See “Case Study: Misdiagnosis,” on page 22.)

If elimination accidents occur when the owner is home as well as when the dog is left alone, it’s more likely a housetraining problem

Never punish! Rather, consider separation anxiety as a potential cause if your dog damages your home (especially doors or windows) when you’re away.

than a separation issue. Separation-related destruction is usually directed toward escape efforts - chewing or clawing at or through doorframes, windowsills, and walls. If the destruction is more generalized throughout the house, it points toward one or more of the other possible causes, rather than an isolation issue. A strategically located video camera or sound-activated tape recorder can help identify possible outside stimuli, such as visitors to the home or unusual noises, that might trigger what otherwise may appear to be separation-related behaviors.

A continuum
Distress over being left alone is not always a full-blown separation anxiety problem. First, a dog may suffer from a mild distress to a severe anxiety disorder. “Distress” indicates a lower intensity of stress behaviors when the dog is alone, while “anxiety” is an extreme panic attack.

The distinction between “isolation” and “separation” is equally important. Isolation distress means the dog doesn’t want to be left alone - any ol’ human will do for company, and sometimes even another dog will fill the bill. True separation distress or anxiety means the dog is hyper-bonded to one specific person, and continues to show stress behaviors if that person is absent, even if other humans or dogs are present.

Our Cardigan Corgi, Lucy, suffers from moderate isolation distress - she doesn’t like to be left alone outdoors. Before we realized the significance of her behavior, she managed to injure herself badly, falling off a stone wall onto cement steps eight feet below in her persistent attempts to reach us through a window. Indoors, her isolation distress is milder. She may bark briefly if we leave her alone downstairs, but quickly calms and settles.

Missy, on the other hand, demonstrates true separation distress. The eight-year-old Australian Shepherd had been in at least four different homes prior to joining our family last fall. As is sometimes the case with dogs who have been rehomed numerous times, she attached herself to one of her new humans (me) completely and almost instantly.

If our whole family is in the barn, and I go back to the house for some reason, Missy could care less that my husband is still with her in the barn; she becomes hyper-vigilant, watching anxiously for me to return, ignoring Paul’s attempts to reassure her or engage in other activities. Fortunately for us, her stress level is mild; other than some scratches inflicted to our kitchen door on the second day of her arrival to our home, she’s done nothing destructive; her level of stress over my absence is low, and tolerable, and consists primarily of pacing, whining, and barking. But it may explain why we’re at least her fifth (and final!) home.

Behavior modification
There are a number of steps you can take to resolve your dog’s isolation- or separation-anxiety behavior. The program spelled out in the accompanying sidebar, “Preventing Separation Anxiety” (see page 23) can also be used to modify an existing isolation/separation condition. However, you will progress much more slowly through the steps of the program with a dog who suffers from separation-related behaviors; your dog’s strong emotional response to being left alone will make this a much more challenging proposition.

Here are some other avenues to explore, to complement your modification work:

• Exercise your dog well before you leave. A tired dog has less energy with which to be anxious and destructive. End exercise sessions 20 to 30 minutes before you go, so he has time to settle down.

• Five minutes before you leave, give him a well-stuffed Kong to take his mind off your imminent departure (See “King Kongs,” Whole Dog Journal October 2000).
• Make your departures and returns completely calm and emotionless. No huggy/kissy “Mummy loves you” scenes. If he gets excited and jumps all over you when you return, ignore him. Turn your back and walk away. When he finally settles down, say hello and greet him very calmly.
• Defuse the pieces of your departure routine by also doing them when you are not leaving. Pick up your car keys and sit down on the sofa to watch TV. Dress in your business suit and then cook dinner. Set your alarm for 5 a.m. on a Saturday, then roll over and go back to sleep.
• Mix up the pieces of your departure routine when you are leaving, so his anxiety doesn’t build to a fever pitch as he recognizes your departure cues. We are creatures of habit too, so this is hard to do, but can pay off in big dividends. Eat breakfast before you shower instead of after. Pick up your keys and put them in your pocket before you take your dog out for his final potty break. Put your briefcase in the car while you’re still in pajamas. Make the morning as unpredictable as possible.
• Use a “safe” cue such as “I’ll be back,” only when you know you’ll return within the time period your dog can tolerate. As suggested in Patricia McConnell’s wonderful booklet on separation anxiety titled “I’ll Be Home Soon,” this helps your dog relax, knowing he can trust you to return.
• Explore alternative dog-keeping situations to minimize the occasions when you do have to leave him alone - doggie daycare may be suitable for some dogs, but not for others. You may be able to find a neighbor or relative who is house-bound and might appreciate some canine companionship.
• If you are considering adoption of a second dog, try borrowing a calm, stable, compatible dog from a friend, to see if that helps to relieve your dog’s distress.
• Try using Comfort Zone (DAP) plug-ins and sprays in his environment to help ease his anxiety. (See Whole Dog Journal January 2004, “Please Appease Me”).
• Remove as many other stressors from your dog’s world as possible to help him maintain his equilibrium in your absence. No choke chains, shock collars, physical or harsh verbal punishment (especially in connection to his anxiety behaviors).
• Consider working with a behavior professional to be sure you’re on the right path - and to help you explore the possibilities of using anti-anxiety medications to maximize the effectiveness of your modification efforts.

Fixing separation anxiety is hard work. It’s all too easy to get frustrated with your dog’s destructive behavior. Remember that he’s not choosing to do it out of spite or malice - he is panicked about his own survival without you, his pack, there to protect him. It’s not fun for him, either; he lives in the moment, and the moments that you are gone are long and terrifying. If you make the commitment to modify his behavior and succeed in helping him be brave about being alone, you’ll not only save your home from destruction, you will enhance the quality of your dog’s life immensely - as well as your own - and perhaps save him from destruction, too.
