There's some other things you can do but I don't know how severe her seperation anxiety is. The other suggestions I have are for more severe cases.

Give her some time. I'm sure she'll adjust just fine!!

Oh yeah, another thing is to get her used to a schedule and stick with it. Sometimes people will adopt a dog and then stay home 24/7 for a few days then all of a sudden go back to normal work schedules. I'm not saying you did that though. Just saying its good to start them out with a normal schedule.

Good luck and don't hesitate to ask any questions. Welcome to Pet Talk by the way
