Sorry Mrs Wilson, but are you really telling us you left a dog in a room alone with an in season bitch. Why on earth would you do that? Did you not know the bitch was in season. Sorry I can't answer your question and I am at a loss to understand what it is you think you doing.

Have re-read your post and it would seem you did it deliberately, if so it is possible that one or the other has been hurt and they are not going to try again. Mating dog is a lot more complicated than shutting 2 dogs together and hoping for the best. You need to do a lot of research into both dogs then you will need to find someone who is used to matting dogs to come and help you, or you are risking damaging the dogs. What day of the season was the bitch on, had you had a premate test
