Hello I am sorry no one picked up your question. It depends who is online at the time you write in and where you post your question. It looks like this was first posted to pet or dog not dog veterinary.
Your dog is hiding most likely due to pain. This breed is prone to disc problems in the spine and when it hurts they have a tendency to hide so as not to be picked up or touched due to pain. In fact they may snap at anyone that does approach.
If possible check the gum color. If it is white or pale please get your dog to a veterinarian as soon as possible as it is serious.
If the gums are pink you can try putting a baby aspirin in with some moist food and give that to her. Let her have strict rest even if it means she stays under the bed, put some food and water under the bed with her so she does not have to move much to get it.
Give the aspirin every twelve hours for two days and give with food, but if the gums are pale or white do not give any aspirin see your vet immediately.
I am going to direct you to a site on taking the dog's vital signs so you will know if there is an emergency or if you can keep her home and keep an eye on her .
Again I am sorry that no one picked up your question sooner.
