Hi there! Congratulations to Leila! You are correct as it is close to the end. The gestation period for a dog is about 63 days - give or take. It seems like you are watching out for the correct signs, like nesting behavior. I doubt the other dog is preventing her from giving birth, but it wouldn't be a bad idea to separate them during this time, so she can get comfortable and have access to her own private area. You can also start checking her rectal temperature routinely, a couple of times a day, so you will know for sure when it drops, indicating labor will start soon after. Another good idea (if you haven't already of course) is to take her to her veterinarian for an Xray. The veterinarian can estimate the number of puppies she will be having. This way, if you expect at least 10, and she only births 9, you know there is an issue. Her backbone, like you said, is most likely more visible because her body condition is changing. The puppies grow a lot from 40 days until the end, and they are using her energy to do so. She may be losing body condition (even if her weight is staying the same) because she isn't getting enough nutrition. I included a link below about how to feed a pregnant dog. I also will include one about birthing puppies that is great! It has a lot of good information so you know what else to expect aside from your current knowledge. I hope you find this answer helpful!

    The average 63 days of gestation is counted from the day of ovulation which you would probably not know unless a progesterone level was run. Sperm can stay viable in the female reproductive tract for several days so she may have ovulated before or after she was last bred. You should start taking a rectal temperature three times daily to establish a baseline - a decrease of one degree F indicates that labor should start within 24 hours. I would also recommend taking her to your vet as soon as possible for an x-ray to count the puppies. They might be able to determine how far along she is by looking at the puppies’ bones.
