My mother in law and sister in law both have german shepards that live in same house. One female other male, both just over a year but not from same parents. the female went on season and the both dogs were seperated however the male dog managed to unlock the door the female was in and she pushed the door open. The dogs were in the house alone and so we are not sure if she has been caught or not but there was a lot of her hair away from back end. She is still bleeding after three days of this incident but it only looks same as her season and we were hoping someone could advise if this may occur or if we are lucky and she hasnt been caught.
