Separation Anxiety in Dogs

Common Symptoms of Separation Anxiety continued...

Barking and Howling

A dog who has separation anxiety might bark or howl when left alone or when separated from his guardian. This kind of barking or howling is persistent and doesn’t seem to be triggered by anything except being left alone.

Chewing, Digging and Destruction

Some dogs with separation anxiety chew on objects, door frames or window sills, dig at doors and doorways, or destroy household objects when left alone or separated from their guardians. These behaviors can result in self-injury, such as broken teeth, cut and scraped paws and damaged nails. If a dog’s chewing, digging and destruction are caused by separation anxiety, they don’t usually occur in his guardian’s presence.


A dog with separation anxiety might try to escape from an area where he’s confined when he’s left alone or separated from his guardian. The dog might attempt to dig and chew through doors or windows, which could result in self-injury, such as broken teeth, cut and scraped front paws and damaged nails. If the dog’s escape behavior is caused by separation anxiety, it doesn’t occur when his guardian is present.


Some dogs walk or trot along a specific path in a fixed pattern when left alone or separated from their guardians. Some pacing dogs move around in circular patterns, while others walk back and forth in straight lines. If a dog’s pacing behavior is caused by separation anxiety, it usually doesn’t occur when his guardian is present.


When left alone or separated from their guardians, some dogs defecate and then consume all or some of their excrement. If a dog eats excrement because of separation anxiety, he probably doesn’t perform that behavior in the presence of his guardian.

Why Do Some Dogs Develop Separation Anxiety?

There is no conclusive evidence showing exactly why dogs develop separation anxiety. Because far more dogs who have been adopted from shelters have this behavior problem than those kept by a single family since puppyhood, it is believed that loss of an important person or group of people in a dog’s life can lead to separation anxiety. However, it is uncertain whether these dogs may have originally been relinquished to an animal shelter due to problems caused by separation anxiety. Other less dramatic changes can also trigger the disorder. The following is a list of situations that have been associated with development of separation anxiety.
