3) Keep lights on.
One mistake that owners make is leaving in the morning when it is nice and sunny; they don't turn light on. But, as the day goes by, it can get stormy out and/or an owner may not return home until the sun is setting. When a Pomeranian is home alone and already struggling with the isolation, being in a house that is getting dark only exasperates things. So, leave on a few lights to offer a more comforting environment.
4) Don't keep the house dead silent.
Most Pomeranians with separation anxiety do much better when they have some pleasant background noise. This can be a TV (and if a Pom has this in view, it can be even better since many dogs like to watch the screen) or it can be a radio. Be careful when you choose a channel or station. What may begin with a pleasant show or music can later become tense arguing or loud, obnoxious songs.
5) Do practice runs.
Once you have things set up, do some short practice runs of leaving the house for varying short times. Have each time last anywhere from just one minute to 10 minutes. And continue to do this on a random basis. This way, your Pomeranian will learn that you leaving does not necessarily mean that he will be alone for hours.
