Separation anxiety is a genetic issue. This means that owners do not cause it, however, they can bring it out in a dog and intensify it. Research has shown that dogs that are noise shy, such as a fear of thunderstorms tend to also have separation anxiety.
Separation anxiety is a panic attack and is very similar to a panic attack in people. It is not fun to have and if it happens often enough, such as when a dog is left alone frequently, can cause the dog’s quality of life to degrade. Imagine being afraid for eight to ten hours, five or more days a week. It is also important to understand that separation anxiety is very stressful, and a dog’s health is affected the same as a person from constant stress. Therefore, separation anxiety not only destroys a dog’s mental health, but can also harm their long-term physical health as well.

Before you determine that your dog has separation anxiety, you must rule out medical issues that can cause the same symptoms. This will require a thorough examination by your veterinarian. The examination should check for the following:
CBC, Chemical profile, thyroid profile, urinalysis and fecal exam, dental health, GI distress, diabetes, renal failure, colitis, and inflammatory bowel disease.
After you have ruled out any medical reasons for your dog’s behavior you can then examine the behaviors.
Before you label your dog as having separation anxiety, you must determine if your dog is simply behaving as a normal dog. Puppies, chew and destroy things. Is your dog completely housebroken? Is something teasing your dog outside of your home, making him bark? Is your dog marking? Did you change his food or give him a treat that made him unable to wait to eliminate?
A dog can have various levels of separation anxiety. Like any fear or anxiety, it gets worse the longer the dog has it. Older dogs tend not to respond to treatment as well as younger dogs. Therefore, the behavior associated with separation anxiety will not just “go away” or get better with time. It will get worse until it could reach a level were the dog harms himself.
The symptoms are:
Pacing, drooling, vocalization, destructive behavior and inappropriate elimination of urine and feces, usually randomly throughout the house. Often the feces will have mucus in them and do not appear the same as normal stools.
If you determine that your dog does suffer from separation anxiety, it is best to contact a certified canine behavior consultant because the treatment can vary widely and should be tailored to your living arrangements and the dog’s needs. In some cases, medication may be necessary and, in that case, you would need to consult with a veterinarian behaviorist who understands which medications are best and how to administer the medications and how to wean your dog off of them. A non-veterinarian behavior consultant who understands the medications can work with your veterinarian.
The question that I am often asked is how can a person determine if a puppy is prone to separation anxiety. There is no hard and fast rule, but typically if a young puppy cannot be crated, it is often a good indication that the puppy is prone to separation anxiety.
Remember, the sooner you address the problem the better the chance you will be able to get it under control. All behaviors are learned very quickly. An example is a dog who becomes frightened of thunderstorms and as he experiences more storms, he learns that as the barometric pressure changes, a storm is coming and starts to shake before the storm arrives. He will even act as if a storm is coming when the pressure changes and no storm comes.
