Still waiting. A reasonable window for puppy birth

Its Saturday morning, Mar. 12....and Dixie is well.  She is still scratching behind chairs, when we let her out of her pen.  But no signs of serious labor yet.  The rainy weather has prevented us from taking her on walks, but today looks to be dry, so I definitely will be taking her out.  Rest assured, Dixie looks to be having a normal healthy pregnancy.  She looks to be in good spirit, and still enjoys a walk.

So what is the date by which Dixie has to have her litter?  Counting 63 to 70 days after the first mating is considered a reasonable waiting period for dog to have her litter.  Dixie's mating dates were Sept 7, 9,  and 11.  If by Day 70, which is next Friday, March 18, Dixie has not had her litter, then the veterinary needs to get involved.

Dixie is now on her 64th day, but she may not have concieved from her first mating.  It could have been from her second or third mating.  .  So it is really not a concern that we are still waiting for this litter.
