The day before yesterday our 8 year old GSD, Keeli, ran off. She was gone for an hour and we think she is in heat. We found her by herself far away from the house. Is there a possibility that she could have gotten pregnant in that time, if so she is in great danger! Because she is old and we don't have the money to take her to the vet. She has had three litters in her life. Please help! I'm so worried! If so, how long is it until signs of pregnancy will show?
