Hi Belinda
If your dog was not truly in her heat period i.e. and had been bleeding prior to this event, she would not have been able to get pregnant when this happened. However, the male sounds a determined kind of guy and keeping him away from her when she does come fully into her heat period is going to be a nightmare. You will need to keep them separate and he will make every attempt to get to her if kept in the same space. Can one of them stay away during this time? I hope its not already too late!
