We found a stranded dog on new years day. She was at the last of heat blessing for a few days still. She is showing signs of pregnancy now. I can't determine a date she could have mated

Well first off, thank you for taking care of this sweet girl. A dogs gestation period is 62-63 days. With her being a larger dog, she likely won't have any issues having puppies. If you feel like she is getting a larger belly, I would have your vet take an x-ray. If they can see the skeletons of the puppies, then this proves that she is at least 45 days along. That will give you approximately 2 week window of when she could have the puppies. Unfortunately, there isn't any good test to tell you the exact day of when they will be born. Most dogs will have their temperature drop below 99 degrees F when they are going to go into labor within 24-48 hours. Unfortunately, this doesn't ALWAYS happen. When she does go into labor just give her some space and don't bother her too much. If you mess with her too much, it can actually slow down labor. I hope this helps !
