You may see a vaginal discharge with a faint pinkish color, but there should not be any blood. A dog’s pregnancy lasts from 58 to 63 days or more, and during this course, it is normal for them to release vaginal discharge. If it is a pink tint, it is entirely normal, but if it is red, it is a sign that you might be dealing with some pregnancy complication. Call your vet immediately and take your dog for an examination.
