Are you experiencing separation anxiety or fear that Foxy will have anxiety? If she is experiencing it, what is she doing? Do you see any patterns? I can probably give more details with the answers to these questions.
In general, reducing separation anxiety requires patience and planning on your part. Start with short trips away from her, such as a 20-minute visit to a neighbor's house. Reward her AS YOU LEAVE. Continue to extend the time away until she realizes that you will return.
DO NOT have a celebration when you come home. Ignore her for a while when you return. After you've settled in, say you've changed clothes after work and gone into the kitchen to make some tea for yourself. THEN pay attention to her. If homecoming is a big party, she will learn to anticipate that.
Instead, make leaving a wonderful event. Maybe she gets treats (a stuffed Kong to keep her busy for a while).
You might also try setting up a GoPro and looking at video of what she is doing when you are away. If she is anxious at the beginning, but later settles, then you know she eventually gets the idea and she will likely improve with time. If she is not anxious at the beginning, but gets more so as the time progresses, it may mean she is bored. Setting up a toy that gives out timed rewards could be helpful. If she is anxious the whole time, this indicates more of a true separation anxiety situation.
Crating an anxious dog (after the dog has learned that crating is a reward, not a punishment), making the crate extra comfy, giving Kongs for long-lasting chewing/play, trying herbals for relaxation, and soft music to help drown out any anxiety-producing sounds (traffic, mail delivery, etc) can be a huge help to resolve separation anxiety.
Once you've tried these things, if they aren't working, keep a detailed journal. Take the journal to your vet to show that the problem is real (not boredom). Have him/her check for any medical reasons for the anxiety, then consider medication.
All The time!
If you can afford it try hiring someone to walk your dog during the day. Chew toys and Kong's are always helpful to reduce anxiety. I have also left music on so the dog doesn't feel alone. cesar millan has some great training videos on how to reduce the anxiety!
