Hello.My dog is going to be a First Time Mom and should already be towards the End.I just wanted to know when to start counting the days?If its from the first time mating then today isDay60.Last time she mated was Sept12.I know some of the first signs but she hasnt showed any of them.No nesting,no bloddy discharge,she still eats,she's just clingy.Is it possible that she does not want to give birth because our 2nd dog is around?her spinal cord started showing more is it cause of her tummy weight?

The average 63 days of gestation is counted from the day of ovulation which you would probably not know unless a progesterone level was run. Sperm can stay viable in the female reproductive tract for several days so she may have ovulated before or after she was last bred. You should start taking a rectal temperature three times daily to establish a baseline - a decrease of one degree F indicates that labor should start within 24 hours. I would also recommend taking her to your vet as soon as possible for an x-ray to count the puppies. They might be able to determine how far along she is by looking at the puppies’ bones.
