What is separation anxiety in dogs?
Separation anxiety in dogs describes a condition in which a dog exhibits distress and behavior problems when separated from its handler. Separation anxiety typically manifests within minutes of departure of the handler. It is not fully understood why some dogs suffer from separation anxiety and others do not. The diagnosis process often leads to a misdiagnosis as it is difficult to differentiate from other medical and behavioral problems. The behavior may be secondary to an underlying medical condition. With chronic stress, impairments to physiological health can manifest. Increased stress in the dog alters hormone levels, thus decreasing natural immunity to various health problems.
