Question

Answer
Hi Kelly.  I'm going to send you the website address to a great "Whelping Calendar" that I use.  Just type in the date that your female mated, at the top, and the program will calculate her estimated due date and will supply you with a detailed listing of what signs to look for, and what to expect over the term of her pregnancy.

The website address is as follows:

Good luck, and please do not hesitate to contact me if you have additional questions.
