strange behavior

Question
hi, i have 18 months old female gs. about a week ago she started to treat her toys as her puppies, she refuses to eat, her breathing is very loud, she doesn't sleep at night.
all she wants to do is just carry her toys into her bed.please, let me know if this behavior is normal.

Answer
I wouldn't call such behavior normal, but it isn't unusual.  It most often happens with intact females as they come into season, or afterwards along with a false pregnancy.  

I don't know there is much to do about it aside from waiting it out.

You might try to distract her with extra attention and play.  A good vigorous walk solves many problems.
