Many dogs will chew on anything that they can reach. This includes table legs, blankets and bedding and food bowls. It is a projection of their anxiety and chewing works (to some degree) as a calming method. The destruction of items is done during a bombardment of overflowing emotions… A dog will be caught in a rush of panic and training as to what or what not to chew is difficult to summon.
Often as the hours tick by, stress will mount and eventually build into a type of panic. A Yorkie may repeatedly jump, spin around and smash into walls or other areas that are being used to confine him.
Excessive drooling -
When a dog works himself up into a frenzy, there may be excessive drooling.
Have urination or bowel movement "accidents"-
Some owners wonder if their dog is purposely 'misbehaving'. However, when a dog becomes extremely upset, the body can "let loose" leading to urination or elimination.
A dog may pace back and forth; some will do this for hours before finally tiring out.
Excessive licking -
This is a nervous behavior and as with chewing, a dog may do this as a self-calming method. This can be very detrimental, as excessive self-licking can lead to hot spots in which hair thins or the skin becomes completely bald. This can lead to secondary infections.
Whether a Yorkie curls in his bed or stands to try and look out of a window, he may consistently whine in a high-pitched vocalization.
This is the term that means "eating feces" and while many things can cause a dog to do this (including lack of proper nutrition- See Feeding), Yorkies that only do this when home alone, may be doing this purely out of nervousness.
When the Owner Returns Home
Since a Yorkshire Terrier with separation anxiety is experiencing such an intense response to being home alone, it is often difficult for the puppy or dog to quickly rebound once an owner is home. When an owner comes home to greet a dog that has been overly anxious, that dog may then:
Have excitement urination -
A dog can become so excited, that he displays excitement urination - This has nothing to do with housebreaking, it is a release of urine that happens when the body "lets go" of its anxiety and fear
Have a rapid release of pent up energy and emotions -
A Yorkshire Terrier may jump all over his owner, circle around him over and over, jump up and more. While it is normal for a dog to be happy that his owner has arrived back home, dogs with separation anxiety will act in a way that shows they are finally free from a prison of perceived emotional torture.
Become clingy, shadowing the owner -
A dog may behave as if he is afraid to leave his owner's side. He may beg for extra attention.
