hi,my jack russell bitch has entered her first season .she has been losing blood for four days now.however the postman left our gate open and she escaped.she was only missing for a couple of minutes and was found over at the park by another dog owner.i was wondering if there is any possibility that she may have mated in her abscence or if it is too soon.do not want puppies and was planning her spay after this season so am hoping someone has an idea of the likelihood of pregnancy,thankyou
