Separation anxiety is often triggered by either a high contrast situation – months of the owner home all day followed by sudden eight-hour absences – or some sort of life change – rehoming, a stay at a boarding kennel, a death of a key family member or major change in routine.
Reduce the contrast between when you’re gone and when you’re home. Refrain from smothering him with affection (see the "mental work" options above to discover other ways of interacting with your dog). Regularly interrupt his shadowing you around the house continuously when you’re home by baby-gating him into another room for short periods. This is like practicing a "semi-absence." Do many, many extremely brief (1 – 30 seconds) absences with no fanfare on departure or arrival. Increase physical exercise and mental stimulation.

Here is first consumer-oriented discussion of the use and application of medication in the management and treatment of behavioral problems in dogs. Dogs experience the whole range of psychological problems that humans do; depression, anxiety, fear, aggression, and grief. The dog-owning public is seeking solutions to doggie problems which may include the application of human medications. A Professor of Behavioral Pharmacology at Tufts University School of Veterinary Medicine, author Dodman's approach includes an in-depth understanding of behavior, making key changes in diet, exercise, environment, and at times, prescribing state-of-the-art medication. Case histories enhance the understanding of Dodman's theories. Fascinating reading!
