breeding and due dates

Question
How many days in a dogs heat can you breed them and from which day do you start counting to determine the due date?
Thank you

Answer
Hi. Most people try on days 11 and 13, or on days 12 and 14 of the heat cycle. You really only need to breed them twice. As long as she's in the right part of her cycle, she should take with just two breedings. You start counting from each day she was bred to figure out a due date. Say she was bred today, that counts as day one. You do this for each breeding. Good luck.
