what is wrong with my girl?

Bailey is a 5yr old Lab X, she is not an active dog, spends most of her time hanging out in her fav spots snoozing. She is vaccinated and wormed regularly, Eats Iams mini chunks free choice, Avrage in wieght, not fixed and never bred. Up untill now she has been healthy but I started noticing she shivers lots at first I thought it was the cold but as it grows warmer I realize somthing is wrong. She shakes all day and it is getting worse no other symptoms exist, I can see no cause for it no changes in diet, excersize or environment. She is eating but not drinking as much, she spends a few days a week home alone for a long period of time, inside. She does not mess on the floor, could this be a problem?
Why is she shaking so bad? please help we don't see the vet for a few days yet!

Are you serious? You are waiting DAYS to see a vet!

GO to the vet ASAP your dog could be experiencing renal failure, neurological damage or other more serious problems.

I can't believe you would wait....wait and your dog could DIE!

What Luba said! VET ASAP!!!!

Get her spayed too - there is no reason on earth for her to be intact, and each heat increases her chances of getting pyometra, an often fatal infection of the uterus that requires emergency surgery.

Other people on this board did not take their gravely ill dogs to the vet, and their dogs died.
