Researchers have recently determined that separation anxiety is a symptom of various frustrations rather than a diagnosis. The key symptoms of separation anxiety are: destruction of household items, urinating or defecating indoors and excessive barking.
The team of scientists from the University of Lincoln, UK found that there are four main forms of distress when dogs are separated from their owners. These include when the dog wants to get away from something in the house, or they want to get to something outside. It can also be a reaction to external noises or events as well as simple boredom.
A combination of factors such as the dog’s temperament and the type of relationship it has with the owner will determine whether or not a dog will develop separation anxiety.
Sue’s Note: Dog owners often create separation anxiety in dogs by making dramatic arrivals and departures from their home. It helps to prevent this problem by making arrivals and departures as calm and non-specific as possible. If a dog owner notices any of the behaviors listed above, do not wait to engage the help of a certified canine behavior consultant. The longer the behavior is allowed to continue the harder it will be to cure. Cats can also suffer from separation anxiety. To find a qualified behavior consultant go to iaabc.org

Because of the unique combination of issues that contribute or cause separation anxiety, diagnosing the problem is difficult therefore a dog owner should not try to solve the problem themselves or go to a dog trainer since this is not a training issue.
