Hi, I work from home so slightly different, but I know that if she is anywhere near me when I'm working she will want my attention, rather than going to sleep. Molly gets walked by hubby in the morning before he goes to work so I start my work early, then 9:30-1:30 she sleeps in her crate downstairs in the kitchen (usually she whines for a wee around 11ish) rather than being upstairs with me in my office. Then 1:30-3ish she has my undivided attention, before going back in her crate from 3-4, and then I usually give up work after that (I'm doing a PhD).
Is there anywhere you can put her so she can't see/hear you?
