I had a gyp do just like you said. I finally got rid of the box. Went out the next day and she had the pups in a dog igloo house so I could not get in to check on them. She had full bags for about a month before she dropped. The problem I had was that I did not know when she got hooked up. She was always busting into my male's kennel. You know how them women are
But I figured she had full bags within a week of getting pregnant so it threw my date off when I expected her to drop. Feel from the sides to see if you can feel some pups. If she is going too long you might want to take her for an ultrasound. Things could have gone bad and your female die. Call your vet and most will do a quick ultrasound without emptying your wallet. Be sure to put her in something just in case she drops on the way.
