Do remember that just because your Pom is always at your side, that this does not mean that you must constantly play or provide interaction.
It is best to teach your dog that there are times when you will be doing tasks (cooking, talking on the phone, reading....anything that you normally do at home) and that they are expected to either stay quietly beside you or play with a toy.
If your Pom is continually jumping up on you or barking to gain your attention, the best course of action is to completely ignore negative behavior and reward desirable behavior.
While you will want your dog to be self confident and able to interact with others in a healthy way, do be happy that your Pom enjoys your company so much. With this said, to have a well-rounded life and to be truly happy, a dog needs to be able to have the right training to be able to engage with other people and other dogs.
