Separation Anxiety in Dogs Can Present a Disaster

Date Published: 08/11/2003
Date Reviewed/Revised: 07/26/2018

The worst cases of separation anxiety present an unlivable disaster for the pet owner. The animal becomes destructive, soils the house, and vocalizes loudly and unabashedly. Since the behavior occurs almost exclusively when the pet is alone, there is nothing to stop him from creating a spectacular mess and annoying the neighbors every time the owner steps out. In milder cases, the dog may show only panting, over-grooming, or pacing, which is not overtly destructive but clearly represents an unpleasant mental state for the patient. Regardless of how mild or severe the situation is, intervention is warranted for the welfare of both the human and the patient.

  • Often the dog begins the anxiety display when he perceives cues that the owner is about to leave (i.e., the owner puts on cologne for work, gets the car keys, takes a shower, makes coffee etc.).
  • Separation anxiety problems can be precipitated by moving to a new home, loss of another pet in the home, or by prolonged separation from the owner. Prior to these events, the dog may have shown no separation anxiety whatsoever.
  • Pets owned by single owners are 2.5 times as likely to have signs of separation anxiety as are pets living with more than one person. Dogs that are housed with other dogs still develop separation anxiety at the same rate as dogs living as the only pet.
  • Senior pets are predisposed to separation anxiety as they develop cognitive changes associated with aging.

Separation Anxiety Vs. Boredom

It seems intuitively obvious that boredom and anxiety are opposite mental states but when you consider that dogs cannot talk, it becomes easier to see how you might misinterpret a dog's behavior. You may come home to find the front door scratched up beyond recognition or the sofa reduced to a pile of stuffing. Was he reacting to his fear of being alone? Was he bored and looking for fun? Was he frustrated because he did not know when to expect his owner to be home? Some dogs exhibit what has been called barrier frustration, in which they become destructive and attempt escape simply in response to being confined.

Separation anxiety is about two things: Separation and anxiety (or fear). Some clues that the problem is separation anxiety and not something else are:

  • The behavior occurs only when the pet is left alone or anticipates being left alone. (The dog who is destructive for fun may well be destructive when he is not left alone.)
  • The pet is hyperattached to the owner. The hyperattached pet follows the owner from room to room and/or constantly wants to be held. Many people enjoy being loved by a dog to this extent, but it is important to realize when some independence must be learned. Further, some dogs with separation anxiety do not have hyperattachment so lack of this trait does not exclude a diagnosis of separation anxiety.
  • Destruction is oriented against barriers such as doors (especially the door where the owner was last seen by the pet).
  • Vocalization during the episode tends to be high pitched and in repeated yips. (This is a regression to a young puppy's distress call in the time of separation from its mother.)
  • The episode begins in the first 30 minutes from the time the owner leaves.

Not every one of these signs must be fulfilled for the diagnosis of separation anxiety to be made but the point is that an effort should be made to determine if the dog is actually showing separation anxiety or if there is some other motivation at work.


Living with a destructive animal is an on-going nightmare. You never know what disaster will be waiting on the other side of the front door and the simple luxury of finding your things where you left them becomes an impossible dream. It would be wonderful if you could simply give the dog a pill and solve the problem; unfortunately, training is the primary focus of solving separation anxiety and medication is an adjunct. Often the owner needs as much training as the dog.

Step One: Discourage Hyperattachment
Dogs will often solicit attention from their owners. Resist the temptation of petting the dog with separation anxiety when approached for play or contact. Be aloof when greeted upon arriving home. Instead the human should be the initiator of contact with the dog.

Do not allow the dog to settle down in close proximity (within one yard) of where the owner is settling down. Arrange objects on the bed or sofa or on the floor so that the dog must settle at a greater distance. If possible, verbally reward the dog for settling at a distance (though take care as continued attention may be seen by the dog as an invitation to approach which is not what we want.) If the dog normally sleeps on the owner's bed, provide the dog with his own bed. You may need to start with the dog bed at the foot of the human bed before ultimately the dog bed is moved to the floor or even outside the room.

If there are other people in the home besides the primary dog caretaker, try to divide the care giving among the different people so that the dog is not as dependent on one person.

Encourage independent play by using interactive toys that do not require human participation (like a Kong toy containing a food reward).

Step Two: Relaxation During Separation
It is also important to create a positive environment while you are gone. There are several ways to achieve this.

Provide a special treat (food, toy or both) only available when the pet is left alone. Do not forget to remove the item when you return home.

The Adaptil (dog appeasement pheromone) diffuser is a plug-in scent-releasing device. The material released is a genetically engineered pheromone normally secreted by mother dogs to their puppies as a message telling them to relax and that everything is all right. The pheromone is odorless to humans. A pump spray is also available but the diffuser continuously releases its message to hopefully keep the anxious dog calm. More recently, a pheromone collar has become available so that the dog simply carries the biochemical message around with him.

Leave the TV or radio on. The dog will not be fooled into thinking that someone is home; the point is to recreate a sense of cozy relaxation. Most people at home relax while listening to the radio or watching TV and the dog often sits in the room relaxed, too. The sound of the broadcast becomes a classically conditioned cue to the dog and may be helpful in creating a sense of comfort.

Step Three: Desensitization To Separation
Dogs readily learn the cues that indicate that the owner will be leaving the house soon. It is helpful to uncouple these cues from the actual leaving. At random times, the owner can go through some of the rituals of leaving: put on cologne, shower, wear work clothes, jingle the car keys, even go outside and lock the door - but then come in again. This helps the dog to remain relaxed when he hears or sees these cues at the times when the owner is actually leaving. It is important to repeat these cues so many times daily that they become meaningless to the dog.

Do not punish the dog for behavior demonstrated in fear.

This usually only leads to more fear or more anxiety. Second, unless the animal is actually in the process of performing the behavior you wish to discourage, the dog will not understand what behavior is being punished.


Currently clomipramine and fluoxetine are the only FDA-approved drugs for the treatment of separation anxiety in the dog. The problem with these medications is that, while positive effects can be seen in the first week of use, they require 4-6 weeks to achieve maximum effect. Because of this, they are often combined with a shorter-acting substance such as trazadone or alprazolam to achieve rapid results.

Clomipramine, a tricyclic anti-anxiety drug so named because of its chemical structure, works by increasing levels of serotonin in the brain. Serotonin is a neurotransmitter associated with pleasant, relaxed sensations. When serotonin levels are high, we fall happily and cozily asleep. Serotonin is also involved with the pleasant sensations associated with eating chocolate, sun-bathing, and falling in love.

Clomipramine may be used once or twice a day. Often a lower dose is started, gradually working up to a higher dose. This drug or any other used is meant as a supplement to training and cannot be expected to work without proper behavior management.

Fluoxetine is more commonly known by its human brand name Prozac®. Like clomipramine, it acts by increasing serotonin levels in the brain. It is usually given once or twice daily in combination with behavior management as described above. As with clomipramine, it takes several weeks to expect to see a meaningful change, although some dogs respond more quickly.

Alprazolam And Trazodone
If actual panic is occurring and simply must be stopped, fast-acting medications are in order at least until the more long term solutions come into effect. Diazepam, more commonly known as Valium®, might be useful in such a situation but the problem is that it will not last long enough to cover several hours of owner-pet separation and is somewhat sedating. Alprazolam (Xanax®), a similar drug that lasts longer, may be more appropriate in this situation. Both these drugs are controlled, meaning certain paper work must be filed with the government in order to prescribe them. There may be a limit on the number of tablets that can be obtained depending on local laws.

Trazodone is also an effective short-acting anxiety medication, typically given 1-2 hours before the anticipated event. It can be repeated 8 hours later if necessary.


Recently, assorted supplements have become available to relieve anxiety. These will not be as potent as the medications listed above but may help and may be adequate on the situation. Some products available include:

  • Alpha-Casozepine - a derivative of cow's milk protein that mimics the inhibitory neurotransmitter GABA. The result is similar to a benzodiazepine like alprazolam but without potential sedation as a side effect. This material is available as an oral supplement or impregnated into kibbled diet.

  • L-Theanine - a component of green tea plants which increases serotonin and can act as inhibitory neurotransmitter. This material is available as an oral supplement.

Separation anxiety commonly requires both behavioral modication as well as medications which means the help of a professional trainer is likely to be needed. Your veterinarian may be able to help you select the appropriate additional expert so as to achieve the best resolution.
