HAHA It was fairly bad one night. I was trying to sleep and I could hear her snore and she was downstairs and we are upstairs. I couldnt believe it! She doesnt have problems breathing when shes not sleeping so I think shes ok.
Many dogs do snore. Some hardly at all, some more than others. As far as I know, in the absence of any breathing problems or airway obstruction (which would probably show up during the day as well, and with other additional symptoms)- this isn't dangerous. If you are worried, consult the vet who may examine her to see if there is any excess tissue causing slight obstruction in the air passages or throat.
There is another thing to consider though. Is she overweight?
If you think she is, then do something about her weight issue, and she may stop snoring so much.
Oh....and buy some good earplugs in the meantime!
I dont think that you have to worry
