Separation Anxiety in Dogs
Common Symptoms of Separation Anxiety continued...
Escaping
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.
Pacing
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.
Coprophagia
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. However, 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. 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.
Change of Guardian or Family
Being abandoned, surrendered to a shelter or given to a new guardian or family can trigger the development of separation anxiety.
Change in Schedule
An abrupt change in schedule in terms of when or how long a dog is left alone can trigger the development of separation anxiety. For example, if a dog’s guardian works from home and spends all day with his dog but then gets a new job that requires him to leave his dog alone for six or more hours at a time, the dog might develop separation anxiety because of that change.
Change in Residence
Moving to a new residence can trigger the development of separation anxiety.
Change in Household Membership
The sudden absence of a resident family member, either due to death or moving away, can trigger the development of separation anxiety.
