pacing and panting all night

I have a 11 month old Golden Retriever. She is healty and lovely. She sleeps in our bedroom for about 6 months.Last night in the first time she was pacing and panting all night, restless. She seemed to be afraid something. We took her outside and walked about 10 mins. She was fine. But she continued to be pacing and panting after we took her to the bedroom. Any suggestions? Thanks for your help.

Panting and pacing can be due to pain, or anxiety (such as thunderstorm phobia).  Dog's can hear thunderstorms when we can't hear them due to their superior hearing.  So even if the thunderstorm was not in your neighborhood, she could still hear it.

Other reasons for panting and pacing are back pain, or, pain from impacted anal glands, or, pain from a urinary tract infection, or,  if she is not spayed, it could be frustration from being in heat.  There are an unlimited number of possibilities.  It would be best to take her to the vet to have this problem analysed, if the problem continues.
