Separation anxiety

Dogs who are left alone inside may suffer from separation anxiety. Some may show their fear and resentment by barking. The ideal way to prevent this problem is to train a dog to be left alone. Leave your puppy in a room by itself. Say "quiet" with a very serious attitude, and leave the room. If the puppy barks, return, say "quiet" and leave again. If the puppy is quiet for a brief period, return and praise it. Extend your time away from the puppy and, upon returning, praise it for being quiet.

If your puppy cries non stopping, then leave him alone, and wait until he calms down. After he has been quiet for about 1 minute, come back and give him lots of "good boy"/"Good girl". Your puppy needs to understand that screaming is not the way to call for attention. He/she will get attention independently of his behavior.

Separation anxiety is a common problem for shelter puppies and dogs. A well bred and properly raised puppy should never have this problem.

In serious cases, there are medications that you can give to your dog. Ask your veterinarian.
