>We left the two out together in the daytime for about a week, but now the problem starts. How do i know when her expected whelping date is? Do I count from the first day they tied or the last day?
I am wondering if your joking? You seem to be embarking on a potentially life threatening experience for your bitch with barely the most basic idea of what is involved.
I take it that both your dogs have been x-rayed Hip scored? Elbow scored, eye tested, DNA tested for prcd-PRA (or come from parents that were DNA cleared). That they are good working dogs, and/or had good results at shows, and are of excellent breed type and temperament.
It's very lucky that you have the ideal mate for your bitch in your own dog, most breeders search high and low for the best mate, often travelling many miles, even abroad.
With thousands of your breed bred each year there is no shortage of this breed and if your dog shave nothing special to offer other than fertility then you would be best to terminate the pregnancy, (by getting the Alizin injection after her season finishes and before she reaches 6 weeks from first mating) especially if the required health tests have not been completed with satisfactory results.
Buyers are becoming wiser and wiser and will take you to court if the pups develop an issue that could have been avoided by health screening.
